Product details
Overview
SE20PBHM3/85A from Vishay General Semiconductor is an AEC-Q101-qualified surface-mount ESD-capable rectifier in SMP (DO-220AA) package, rated for 100 V repetitive peak reverse voltage (VRRM), 2.0 A average forward current (IF(AV)), and 32 A non-repetitive surge current (IFSM). It delivers low forward voltage drop (0.85 V at 2.0 A, TA = 125 °C) and 5 μA max reverse leakage at rated voltage, supporting rail-to-rail protection in automotive power rails.
For engineers reviewing the SE20PBHM3/85A datasheet, SE20PBHM3/85A pinout, SE20PBHM3/85A application, or SE20PBHM3/85A equivalent, key selection criteria include its automotive-grade MSL Level 1 qualification, 175 °C maximum junction temperature, SMP package compatibility with automated placement, and verified ESD immunity per AEC-Q101-001 (H3B class, >8 kV HBM).
Technical Context
This device is a single silicon planar junction rectifier optimized for high-reliability DC line protection. Its oxide planar chip structure enables low VF, fast recovery (trr = 1.2 μs typical), and stable performance across -55 °C to +175 °C operating range.
The SMP (DO-220AA) package features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, with JESD 201 Class 2 whisker resistance and UL 94 V-0 molding compound - meeting automotive PCB assembly and long-term reliability requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SE20PB-M3/85A | Commercial-grade (M3) version; same electrical specs but JESD 201 Class 1A whisker test and no AEC-Q101 qualification | Approved for industrial/consumer use only; not validated for automotive temperature cycling or humidity testing | Select when cost-sensitive non-automotive designs require identical VRRM, IF(AV), and package |
| SB2100-E3/52T | Higher VRRM (100 V), same IF(AV) (2.0 A), but slower trr (3.5 μs) and no AEC-Q101 or ESD certification | Lacks automotive qualification and ESD immunity data; higher VF (0.95 V typ. @ 2 A) | Consider only for legacy industrial designs where ESD robustness and fast recovery are not required |
Compared with SE20PBHM3/85A, the SE20PB-M3/85A offers identical electrical performance at lower cost but omits automotive qualification and enhanced whisker resistance, while SB2100-E3/52T trades ESD immunity and speed for broader distributor availability - making SE20PBHM3/85A the sole choice for new AEC-Q101-compliant designs requiring integrated ESD hardening.

FAQ
What is the maximum junction temperature rating for SE20PBHM3/85A?
The SE20PBHM3/85A has a maximum junction temperature (TJ) of +175 °C, validated per AEC-Q101 stress testing. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial enclosures without forced cooling. The device's RθJM of 20 °C/W further supports thermal management via direct PCB mounting. Always verify actual board-level temperatures using thermal simulation or measurement with SE20PBHM3/85A in final layout.
Does SE20PBHM3/85A support lead-free reflow soldering?
Yes, SE20PBHM3/85A meets MSL Level 1 per J-STD-020 and is qualified for peak reflow temperatures up to 260 °C, fully compatible with standard lead-free soldering processes. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102, and the HM3 suffix confirms JESD 201 Class 2 whisker resistance - critical for long-term solder joint integrity in automotive applications.
How does the ESD capability of SE20PBHM3/85A compare to standard rectifiers?
SE20PBHM3/85A is specifically characterized for ESD immunity per AEC-Q101-001 Human Body Model (contact mode), achieving Class H3B (>8 kV). Standard rectifiers like SE20PB-M3/85A lack this validation. This makes SE20PBHM3/85A suitable for direct placement at connectors or exposed lines where ESD events occur, eliminating need for external TVS devices in many designs.
What is the forward voltage drop of SE20PBHM3/85A at full rated current and elevated temperature?
At 2.0 A forward current and 125 °C ambient temperature, the SE20PBHM3/85A exhibits a typical forward voltage drop of 0.85 V, with a maximum of 0.95 V per datasheet specifications. This low VF reduces power loss and self-heating in continuous-duty applications such as always-on automotive modules, directly contributing to improved system efficiency and thermal margin.
Is SE20PBHM3/85A pin-compatible with other devices in the SE20P family?
Yes, all SE20P-series rectifiers - including SE20PBHM3/85A, SE20PDHM3/85A, SE20PGHM3/85A, and SE20PJHM3/85A - share identical SMP (DO-220AA) package dimensions, pinout, and thermal pad layout. Only the VRRM rating differs (100 V, 200 V, 400 V, 600 V respectively), allowing drop-in replacement during design iteration or voltage-scaling upgrades without PCB changes.
