Detailed Description

High-efficiency Schottky rectifier diode, 3 A class, 40 V reverse voltage rating (typical for 1N5822 family), axial through-hole Case B (DO-201AD). Very low forward voltage drop and minimal reverse recovery charge for cooler operation and higher power conversion efficiency. Suitable for low-voltage, high-current rectification in power supplies and DC-DC converters. G suffix indicates RoHS-compliant, lead-free “Green” version. Supplied in bulk.

Key Features

Schottky barrier technology for fast, efficient rectification

Low forward voltage drop (typically ~0.5–0.7 V at a few amps)

High average rectified current capability around 3 A (family standard)

High surge current capability (short-duration peaks, typical family spec ~80–100 A)

Very low reverse recovery (majority-carrier device) for high-frequency use

Through-hole axial package for rugged mounting and good heat dissipation via leads

Wide operating junction temperature range (typically up to 150°C)

RoHS and lead-free “G” code variant

Key Advantages

Higher efficiency than standard silicon rectifiers, reducing heat and losses

Stable performance at high ripple currents and switching frequencies

Simple two-lead axial format for easy retrofit and field repair

Strong surge handling helps survive inrush and fault conditions

Lower EMI due to negligible reverse recovery compared to PN diodes

Packaging

Type: Through-hole axial diode, Case B (industry-standard DO-201AD form factor)

Material: Molded epoxy body; tin-plated copper leads for good solderability

Size (typical DO-201AD): Body diameter about 5–6 mm; body length about 9–10 mm; lead diameter about 1.2–1.3 mm; ample lead length for bending and anchoring

Pin configuration: Two axial leads; banded end is cathode, unbanded end is anode

Thermal characteristics: Axial body aids heat spreading through leads and PCB copper; supports operation to high junction temperatures (family typical up to 150°C); use adequate airflow and copper area for lower thermal resistance

Electrical properties (family-typical for 1N5822): VRRM ~40 V, IF(AV) ~3 A, VF ~0.5–0.7 V at rated current, IR ~1 mA at VR and 25°C (rises with temperature), IFSM ~80–100 A (8.3 ms half-sine). Always confirm exact values in the Micrel/Microchip datasheet provided on our site.

Supplier device package: B

Mounting: Through hole

Shipment: Bulk

Lifecycle

Status: Active, widely used and supported. Not nearing discontinuation based on current market presence of the 1N5822 family.

Equivalent or alternative models (verify ratings and package specifics before substitution):

- Micrel/Microchip: 1N5822G (this listing), MBR340 family variants (similar 3 A, 40 V class; check datasheet)

- onsemi: 1N5822 (DO-201AD), MBRS340 series (SMD)

- Vishay: 1N5822 (DO-201AD), SS34 (SMA, 3 A, 40 V)
