Detailed Description

JANTX2N6438 is a MIL‑PRF‑19500 JANTX screened silicon PNP power bipolar junction transistor in a single‑device configuration. Voltage class 120 V and current class 25 A. Designed for high‑reliability power switching and linear service in aerospace, defense, and other mission‑critical systems. RoHS non‑compliant due to hermetic and leaded construction. Main category Discrete Semiconductor. Small classification Transistors – Bipolar BJT – Single. Base product number 2N6438. Packaged and shipped in bulk. In stock quantity reference 2644 units available, subject to prior sale.

Key Features

PNP polarity, single transistor

High current capability 25 A class for robust power stages

High voltage capability 120 V class for wide operating margin

JANTX screening per MIL‑PRF‑19500 for high reliability

Hermetic construction for moisture and contamination resistance

Wide safe operating area with proper heatsinking

Low thermal resistance case for efficient heat removal

Excellent mechanical ruggedness for shock and vibration environments

Lot traceability and consistent screening flow

RoHS non‑compliant, tin‑lead finishes for legacy and hi‑rel builds

Key Advantages

Reliability and consistency from JANTX military‑level screening

Thermal headroom with metal can package that bonds to a heatsink

Easy second sourcing within the same 2N6438 family and screening levels

Predictable performance in both linear and switching roles

Long field life and stable parameters over temperature

Suitable for negative high‑side and pass‑element topologies thanks to PNP polarity

Packaging

Shipping type Bulk

Case style Hermetic metal power can commonly aligned with TO‑204AA also known as TO‑3 or equivalent per datasheet

Materials Metal cap and base with tin‑lead plated terminals typical of JAN devices

Pin configuration Standard TO‑3 convention pin 1 Base, pin 2 Emitter, case Collector verify with the datasheet for your lot

Mounting Through‑hole chassis or heatsink mount using two mounting holes with insulating hardware as required

Thermal characteristics Very low junction‑to‑case thermal resistance when properly mounted, enabling high power dissipation. Use thermal grease and mica or silicone pads as needed. Observe derating curves in the datasheet

Electrical properties at a glance PNP type, VCEO 120 V class, continuous collector current 25 A class, designed for high surge capability and moderate gain. Exact hFE, VCEsat, and SOA must be taken from the datasheet for your screening lot

RoHS status RoHS non‑compliant, intended for hi‑rel and legacy tin‑lead processes

Lifecycle

Status Mature, supported for high‑reliability and defense programs. Not an end‑of‑life announcement product to our knowledge, but availability is build schedule dependent

Equivalent and alternative models within the same family

- JAN2N6438 JAN level screening

- JANTXV2N6438 tighter screening level than JANTX

- JANS2N6438 highest screening level for space and the most stringent flows

- 2N6438 commercial or industrial grade for non‑mil applications

Second source options Multiple hi‑rel manufacturers produce the 2N6438 family to MIL‑PRF‑19500. Pin‑for‑pin alternates with matching screening levels are available. Because SOA, die technology, and test flows can differ between vendors, Y‑IC recommends a cross review before substitution
