Product details

Overview

SE20PAJHM3/I from Vishay General Semiconductor is an AEC-Q101-qualified surface-mount ESD-capable rectifier in SMP (DO-220AA) package, configured as a single silicon junction diode with 600 V maximum repetitive peak reverse voltage (V_RRM), 2.0 A average forward current (I_F(AV)), and 0.85 V forward voltage at 2.0 A and 125 °C - used for rail-to-rail and power line polarity protection in automotive ECUs.

For engineers reviewing the SE20PAJHM3/I datasheet, SE20PAJHM3/I pinout, SE20PAJHM3/I application, or SE20PAJHM3/I equivalent, key selection criteria include its MSL Level 1 rating, 175 °C max junction temperature, 1.2 μs typical reverse recovery time, 13 pF junction capacitance at 4.0 V, and automotive-grade HM3 suffix compliance with JESD 201 Class 2 whisker testing.

Technical Context

This device implements an oxide planar chip junction structure optimized for low forward voltage drop and fast switching, with ESD immunity exceeding 8 kV per AEC-Q101-001 Human Body Model (contact mode). Its thermal design supports junction-to-mount resistance of 20 °C/W when mounted on 5.0 mm × 5.0 mm, 2 oz. FR4 PCB.

The SE20PAJHM3/I operates across -55 °C to +175 °C junction temperature range and delivers stable reverse leakage ≤100 μA at 125 °C under rated V_R, enabling reliable performance in under-hood automotive environments where thermal cycling and electrical transients are common.

FAQ

What is the maximum junction temperature rating for SE20PAJHM3/I?

The SE20PAJHM3/I has a maximum junction temperature (T_J) of +175 °C, validated per AEC-Q101 stress testing. This rating allows sustained operation in under-hood automotive locations and high-power industrial enclosures where ambient temperatures exceed 125 °C. The SE20PAJHM3/I maintains specified electrical parameters up to this limit when thermal design adheres to R_θJM = 20 °C/W mounting conditions.

Does SE20PAJHM3/I meet automotive qualification standards?

Yes, SE20PAJHM3/I is fully AEC-Q101 qualified, including human body model ESD testing (>8 kV contact mode), temperature cycling, and high-temperature operating life. Its HM3 suffix confirms compliance with JESD 201 Class 2 whisker resistance and automotive-grade material specifications. The SE20PAJHM3/I is intended for use in automotive power management, body electronics, and ADAS subsystems.

What does the "/I" suffix indicate in SE20PAJHM3/I?

The "/I" suffix in SE20PAJHM3/I denotes a specific tape-and-reel packaging variant defined by Vishay for internal order fulfillment and logistics tracking. It corresponds electrically and mechanically to SE20PJHM3/84A but uses an alternate reel identification code. The SE20PAJHM3/I shares identical die, SMP (DO-220AA) package dimensions, marking, and all electrical characteristics with other HM3-suffix variants.

What is the typical reverse recovery time of SE20PAJHM3/I?

The SE20PAJHM3/I has a typical reverse recovery time (t_rr) of 1.2 μs, measured at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value supports efficient operation in moderate-frequency rectification circuits up to ~100 kHz, making the SE20PAJHM3/I suitable for DC-DC input stages and power rail clamping where fast turn-off reduces switching losses and ringing.

Is SE20PAJHM3/I compatible with lead-free reflow processes?

Yes, SE20PAJHM3/I meets MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C, fully compatible with standard lead-free soldering profiles. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability requirements, and the molding compound satisfies UL 94 V-0 flammability rating - ensuring robust manufacturability in high-volume SMT lines.
