Key Advantages

Simple to drive with standard bipolar base control

Robust package for high thermal performance on PCB copper planes

Flexible use across many power and signal applications

Well‑supported by Toshiba documentation and reference designs

Easy replacement in existing DPAK footprints

Backed by Y-IC distribution and service

Packaging

Type: SOT-252 (also known as DPAK), surface‑mount

Material: Molded epoxy plastic body with copper leadframe and plated leads; exposed metal tab for heat dissipation

Size: DPAK standard outline (low profile, compact footprint). Refer to datasheet mechanical drawing for exact dimensions

Pin configuration: 3 leads plus exposed tab. Typical PNP BJT mapping is Pin 1 Base, Pin 2 Collector, Pin 3 Emitter, Tab Collector (confirm exact pinout in the datasheet)

Thermal characteristics: Large tab to PCB copper for low thermal resistance; performance depends on copper area and vias. Use wide copper pours and thermal vias under the tab for best cooling

Electrical properties: PNP transistor behavior (collector‑emitter voltage, collector current, hFE gain, saturation voltage, power dissipation are defined in the datasheet). Y gain rank indicates a specific DC gain range selected by Toshiba

Lifecycle

Status: Lifecycle can vary by geography and date code. Not flagged as EOL on our platform at this time

Alternatives and equivalents: Selection depends on key parameters (Vce rating, Ic, Pd, hFE range, package pinout). Because exact matches require detailed specs, please contact our sales team for a precise cross‑reference. We can propose Toshiba or cross‑brand PNP DPAK options after reviewing your requirements
