Product details
Overview
SE20PGHM3/85A from Vishay General Semiconductor is an automotive-grade surface-mount Schottky rectifier in the eSMP® SMP (DO-220AA) package, rated for 400 V repetitive peak reverse voltage (VRRM), 2.0 A average forward current (IF(AV)), and 0.85 V forward voltage at 2.0 A and 125 °C. It delivers low-loss power line polarity protection in automotive infotainment power rails.
For engineers reviewing the SE20PGHM3/85A datasheet, SE20PGHM3/85A pinout, SE20PGHM3/85A application, or SE20PGHM3/85A equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C maximum junction temperature, 1.2 μs typical reverse recovery time, ESD immunity >8 kV HBM (Class H3B), and halogen-free RoHS-compliant construction with JESD 201 Class 2 whisker resistance.
Technical Context
This device is a single-die, oxide planar Schottky rectifier optimized for high-efficiency DC power conditioning in space-constrained automotive modules. Its 1.0 mm profile enables placement on dense PCBs, while the matte tin-plated leads ensure solderability per J-STD-002 and JESD 22-B102.
The SE20PGHM3/85A operates across -55 °C to +175 °C junction temperature range and exhibits 13 pF junction capacitance at 4.0 V / 1 MHz - critical for minimizing switching noise in 12 V/24 V rail-to-rail protection circuits. Thermal resistance is 20 °C/W junction-to-mount (RθJM) when mounted on 5.0 mm × 5.0 mm, 2 oz. FR4 pads.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SE20PGHM3/84A | Same electrical specs and AEC-Q101 qualification; differs only in tape-and-reel packaging (3,000 pcs vs. 10,000 pcs) | Identical use in automotive modules; suited for lower-volume prototyping or pilot builds | Select when smaller reel quantity aligns with production batch size or inventory turnover targets |
| ON Semiconductor SB240HE3_A/H | 400 V VRRM, 2.0 A IF(AV), but 1.1 V VF @ 2 A (25 °C); not AEC-Q101 qualified; TO-277A package | Limited to commercial/industrial use; larger footprint (4.5 mm × 3.5 mm) and higher thermal resistance | Consider only for non-automotive cost-sensitive designs where AEC-Q101 and 1.0 mm height are not required |
Compared with SE20PGHM3/85A, the /84A variant offers identical performance in a smaller reel for flexibility, while SB240HE3_A/H trades automotive qualification and low-profile packaging for lower unit cost in non-automotive applications - making SE20PGHM3/85A the sole choice for volume AEC-Q101-compliant deployments.

FAQ
What is the maximum junction temperature rating for SE20PGHM3/85A?
The SE20PGHM3/85A has a maximum junction temperature (TJ(max)) of +175 °C, validated per AEC-Q101 stress testing. This allows uninterrupted operation in under-hood automotive environments and high-ambient industrial enclosures. The device maintains specified VF and IR performance up to this limit, with thermal design relying on RθJM = 20 °C/W when mounted on recommended 5.0 mm × 5.0 mm copper pads. SE20PGHM3/85A's 175 °C rating exceeds standard commercial diodes by 50 °C.
Is SE20PGHM3/85A pin-compatible with other parts in the SE20P family?
Yes - all SE20P-series devices, including SE20PGHM3/85A, share identical SMP (DO-220AA) package dimensions, pad layout, and 2-terminal anode/cathode configuration. Mechanical compatibility is confirmed by Vishay's standardized mounting pad drawing and 100 % mechanical interchangeability across SE20PB/SE20PD/SE20PG/SE20PJ variants. SE20PGHM3/85A requires no PCB redesign when substituting within the same voltage grade group.
Does SE20PGHM3/85A meet automotive ESD requirements?
Yes - SE20PGHM3/85A is tested and certified to AEC-Q101-001 Human Body Model (HBM) with >8 kV discharge capability (Class H3B). This exceeds the minimum 2 kV requirement for automotive electronics and aligns with ISO 10605 system-level ESD test levels. The device's oxide planar junction and robust metallization ensure repeatable ESD survivability without parameter shift. SE20PGHM3/85A is routinely deployed as first-line ESD suppression in camera and radar module power inputs.
What does the "HM3" suffix indicate in SE20PGHM3/85A?
The "HM3" suffix in SE20PGHM3/85A denotes automotive-grade qualification: halogen-free, RoHS-compliant construction with JESD 201 Class 2 whisker resistance and AEC-Q101 certification. It distinguishes the part from commercial "M3" variants (e.g., SE20PGM3/85A), which lack automotive qualification and Class 2 whisker testing. SE20PGHM3/85A is intended for use in safety-critical and high-reliability automotive subsystems where long-term interconnect integrity is mandatory.
What is the thermal resistance from junction to mount (RθJM) for SE20PGHM3/85A?
SE20PGHM3/85A has a typical junction-to-mount thermal resistance (RθJM) of 20 °C/W when soldered to a 5.0 mm × 5.0 mm, 2 oz. FR4 copper pad. This value is measured per JEDEC standards and enables accurate thermal modeling for automotive ECU power stages. Unlike RθJA (105 °C/W), RθJM reflects direct conduction to the PCB ground plane - making it the relevant metric for thermal design in thermally anchored layouts. SE20PGHM3/85A's low RθJM supports high-power density without external heatsinking.
