Product details
Overview
SE20PJHM3/85A from Vishay General Semiconductor is an AEC-Q101-qualified surface-mount ultra-low-profile ESD-capable rectifier diode in SMP (DO-220AA) package, rated for 600 V repetitive peak reverse voltage, 2.0 A average forward current, 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 infotainment and body control modules.
For engineers reviewing the SE20PJHM3/85A datasheet, SE20PJHM3/85A pinout, SE20PJHM3/85A application, or SE20PJHM3/85A equivalent, key selection criteria include its 600 V VRRM, 175 °C maximum junction temperature, 1.2 μs typical reverse recovery time, SMP package compatibility with automated placement, and automotive-grade HM3 suffix qualification per JESD 201 Class 2 whisker test.
Technical Context
This device is a single silicon planar junction rectifier optimized for high-reliability automotive applications. It features oxide planar chip construction, meets MSL Level 1 per J-STD-020, and delivers low thermal resistance (RθJM = 20 °C/W) when mounted on 5.0 mm × 5.0 mm, 2 oz. FR4 PCB pads.
Its ESD immunity exceeds 8 kV per AEC-Q101-001 Human Body Model (contact mode), and it maintains stable leakage (< 100 μA at 125 °C) and fast switching (trr = 1.2 μs) under transient conditions - enabling robust rail protection in 12 V and 24 V vehicle subsystems.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SE20PJ-M3/85A | Commercial-grade M3 suffix; JESD 201 Class 1A whisker test; no AEC-Q101 qualification | Suitable for non-automotive industrial or consumer applications where automotive reliability is not mandated | Select when cost sensitivity outweighs automotive qualification requirements and operating temperature remains ≤ 125 °C |
| VS-SE20PJHM3/85A | Vishay's alternate ordering prefix; identical electrical specs, package, and qualification - differs only in part numbering convention | No functional or application difference; used interchangeably in design documentation and procurement | Choose based on internal BOM standardization; both share same datasheet (87905) and manufacturing lot traceability |
Compared with SE20PJHM3/85A, the SE20PJ-M3/85A lacks AEC-Q101 validation and whisker testing for harsh environments, while VS-SE20PJHM3/85A offers identical performance but may affect ERP/MRP system mapping - making SE20PJHM3/85A the optimal choice for new automotive designs requiring full compliance traceability.

FAQ
What is the maximum junction temperature rating for SE20PJHM3/85A?
The SE20PJHM3/85A has a maximum junction temperature (TJ) of 175 °C, validated per AEC-Q101 stress testing. This allows sustained operation in under-hood automotive environments where ambient temperatures exceed 125 °C, provided thermal design meets RθJM = 20 °C/W with proper PCB copper area. The SE20PJHM3/85A maintains specified leakage and forward voltage performance up to this limit.
Does SE20PJHM3/85A require baking before reflow soldering?
No - the SE20PJHM3/85A is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and does not require moisture-sensitive device baking prior to reflow. Its molding compound and lead finish are qualified for peak reflow temperatures up to 260 °C, supporting standard lead-free assembly processes without preconditioning. This applies specifically to the SE20PJHM3/85A and all HM3-suffix variants.
How does the HM3 suffix differ from M3 in SE20PJHM3/85A?
The HM3 suffix denotes automotive-grade qualification: SE20PJHM3/85A is AEC-Q101 qualified and meets JESD 201 Class 2 for tin whisker resistance, whereas M3-suffix parts like SE20PJ-M3/85A are commercial grade with Class 1A whisker testing and no AEC-Q101 validation. Both share identical electrical specs and SMP package, but only SE20PJHM3/85A is approved for automotive production use.
What is the reverse recovery time of SE20PJHM3/85A and why does it matter?
The SE20PJHM3/85A has a typical reverse recovery time (trr) of 1.2 μs, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery minimizes switching losses and voltage overshoot in clamp and flyback protection circuits - critical when protecting sensitive 3.3 V or 5 V logic rails from 12 V/24 V transients. The SE20PJHM3/85A's trr enables clean turn-off without inducing EMI in adjacent signal traces.
Can SE20PJHM3/85A replace a standard 1N4007 in automotive designs?
No - while both are rectifiers, the SE20PJHM3/85A is a surface-mount, AEC-Q101-qualified, 600 V/2.0 A ultra-low-profile device in SMP package, whereas the 1N4007 is through-hole, non-automotive, and rated only for 1.0 A average current. The SE20PJHM3/85A offers superior thermal performance (RθJM = 20 °C/W), faster recovery (1.2 μs vs. ~30 μs), and ESD immunity - making it unsuitable as a drop-in replacement but ideal for modern automotive PCBs where space, reliability, and performance are prioritized over legacy through-hole compatibility.
