Product details
Overview
SE10PGHM3/85A from Vishay General Semiconductor is an AEC-Q101-qualified surface-mount ESD-capable rectifier in SMP (DO-220AA) package, rated for 400 V repetitive peak reverse voltage (VRRM), 1.0 A average forward current (IF(AV)), and 25 A non-repetitive surge current (IFSM). It delivers low forward voltage drop (0.86 V at 1.0 A, 125 °C) and ultra-low leakage (<5 μA at rated VR), enabling robust rail-to-rail protection in automotive power line circuits.
For engineers reviewing the SE10PGHM3/85A datasheet, SE10PGHM3/85A pinout, SE10PGHM3/85A application, or SE10PGHM3/85A equivalent, key selection factors include its MSL Level 1 rating, JESD201 Class 2 whisker resistance, 175 °C max junction temperature, and verified ESD immunity per AEC-Q101-001 (>8 kV HBM), IEC 61000-4-2 (>15 kV air discharge), and JESD22-A114.
Technical Context
This device is a single silicon planar junction diode optimized for high-reliability polarity and transient protection in constrained PCB layouts. Its oxide planar chip construction ensures stable reverse leakage (<5 μA at 25 °C) and fast recovery (trr = 780 ns), while the SMP package enables automated placement with 1.0 mm typical height and UL 94 V-0 molding compound.
The HM3 suffix confirms automotive-grade qualification: halogen-free, RoHS-compliant, and tested to JESD201 Class 2 for tin whisker resistance. Thermal performance is characterized by RθJA = 105 °C/W and RθJL = 25 °C/W when mounted on 5.0 mm × 5.0 mm copper pads - critical for thermal management in engine control units and ADAS power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SE10PG-M3/85A | Commercial grade (M3), JESD201 Class 1A whisker test, no AEC-Q101 certification | Limited to non-automotive industrial or consumer applications requiring same electrical specs but lower reliability validation | Select when cost sensitivity outweighs automotive qualification requirements and thermal cycling exposure is moderate |
| SB140-E3/52T | DO-214AA package, 40 V VRRM, higher VF (0.95 V), no AEC-Q101 or ESD immunity data published | Suitable only for low-voltage (<24 V) general-purpose rectification where ESD robustness is not required | Choose only for legacy designs where DO-214AA footprint is fixed and 400 V rating is unnecessary |
Compared with SE10PGHM3/85A, the SE10PG-M3/85A offers identical electrical performance but lacks automotive qualification and whisker-class assurance, while SB140-E3/52T trades voltage rating, ESD capability, and thermal robustness for legacy package compatibility and lower unit cost in non-critical applications.

FAQ
What is the maximum junction temperature rating for SE10PGHM3/85A?
The SE10PGHM3/85A has a maximum junction temperature (TJ) of 175 °C, validated per AEC-Q101 stress testing. This allows uninterrupted operation in under-hood environments such as engine control units and electric power steering modules where ambient temperatures exceed 125 °C. The device maintains specified electrical parameters up to this limit when thermal design adheres to RθJA = 105 °C/W on standard PCB layouts.
Does SE10PGHM3/85A meet AEC-Q101 requirements for automotive applications?
Yes, SE10PGHM3/85A is fully AEC-Q101 qualified, with documented test results for human body model (>8 kV), machine model (>400 V), and IEC 61000-4-2 air discharge (>15 kV). The HM3 suffix explicitly denotes automotive-grade qualification, including JESD201 Class 2 whisker resistance and MSL Level 1 moisture sensitivity - all confirmed in Vishay document 89024, revision 16-Jun-2023.
What is the reverse recovery time (trr) of SE10PGHM3/85A and how does it affect circuit performance?
The SE10PGHM3/85A has a typical reverse recovery time (trr) of 780 ns under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value minimizes switching-induced voltage spikes and electromagnetic interference in fast-switching power rails, making it suitable for protection in DC/DC converter inputs and motor driver feedback paths where rapid polarity reversal may occur.
Can SE10PGHM3/85A replace SE10PG-M3/85A in an existing automotive design?
Yes, SE10PGHM3/85A is a direct drop-in replacement for SE10PG-M3/85A in terms of footprint, electrical specifications, and thermal characteristics. The HM3 variant adds AEC-Q101 qualification and JESD201 Class 2 whisker resistance - enhancements that improve long-term reliability in automotive applications without requiring layout or schematic changes. No requalification is needed beyond confirming system-level ESD performance.
What is the junction capacitance (CJ) of SE10PGHM3/85A and why does it matter in protection circuits?
The SE10PGHM3/85A exhibits a typical junction capacitance (CJ) of 7.0 pF at 4.0 V and 1 MHz. This low value prevents signal degradation in high-speed interfaces (e.g., I²C, LIN, or sensor analog outputs) located near protected power rails. In rail-to-rail ESD protection topologies, low CJ ensures minimal loading and preserves bandwidth without compromising clamping effectiveness.
