Product details
Overview
SE40PBHM3/87A from Vishay General Semiconductor is a surface-mount, AEC-Q101-qualified ESD-capable rectifier in SMPC (TO-277A) package, rated for 100 V repetitive peak reverse voltage, 4.0 A average forward current, and 60 A non-repetitive surge current. It features low forward voltage drop (0.91 V at 4.0 A, 125 °C), 2.2 μs typical reverse recovery time, and operates up to 175 °C junction temperature - used for polarity protection in automotive power lines.
For engineers reviewing the SE40PBHM3/87A datasheet, SE40PBHM3/87A pinout, SE40PBHM3/87A application, or SE40PBHM3/87A equivalent, key selection criteria include its MSL Level 1 rating, JESD 201 Class 2 whisker resistance, halogen-free RoHS-compliant construction, and validated ESD immunity per AEC-Q101-001 H3B (>8 kV HBM).
Technical Context
This device is a single-diode, planar-junction silicon rectifier optimized for high-reliability automotive and industrial DC power line protection. Its oxide-passivated junction delivers stable leakage performance (≤10 μA at rated VR, 25 °C) and robust thermal behavior with RθJM = 6.6 °C/W on 2 oz. FR4 PCB.
The SMPC package enables automated placement with 1.1 mm typical height and meets UL 94 V-0 flammability. The HM3 suffix confirms AEC-Q101 qualification, JESD 201 Class 2 whisker testing, and compliance with automotive-grade material requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SE40PB-M3/87A | Commercial-grade variant (non-AEC-Q101); same VRRM, IF(AV), package, and pinout | Lacks automotive qualification, whisker testing, and extended temperature validation | Select when cost-sensitive industrial or consumer use cases do not require AEC-Q101 compliance |
| ON Semiconductor MUR420G | Higher VRRM (200 V), slower trr (50 ns), TO-220AC package, no AEC-Q101 or ESD rating | Requires through-hole mounting and lacks automotive qualification or ESD hardening | Choose only if higher voltage margin is needed and surface-mount constraints are relaxed |
Compared with SE40PBHM3/87A, the SE40PB-M3/87A offers identical electrical specs but omits automotive qualification and whisker resistance, while MUR420G trades packaging, speed, and qualification for higher voltage - making SE40PBHM3/87A the sole choice for AEC-Q101-compliant, low-profile, ESD-hardened 100 V rectification.

FAQ
What is the maximum junction temperature rating for SE40PBHM3/87A?
The SE40PBHM3/87A has a maximum junction temperature of +175 °C, verified per AEC-Q101 stress testing. This allows uninterrupted operation in under-hood automotive environments and high-ambient industrial settings without thermal shutdown or parameter drift - a key advantage over standard commercial rectifiers rated only to 150 °C.
Does SE40PBHM3/87A meet automotive qualification standards?
Yes, SE40PBHM3/87A is fully AEC-Q101 qualified, including human-body-model ESD testing (Class H3B, >8 kV), JESD 201 Class 2 whisker resistance, and MSL Level 1 reflow compatibility. These qualifications are explicitly confirmed in Vishay document 87954 and apply specifically to the HM3 suffix variant - not to base-M3 versions.
What does the "HM3" suffix indicate in SE40PBHM3/87A?
The "HM3" suffix in SE40PBHM3/87A denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this automotive-grade version from the commercial "M3" variant (e.g., SE40PB-M3/87A), which shares the same electrical specs but lacks automotive validation and enhanced reliability testing.
What is the thermal resistance from junction to mount (RθJM) for SE40PBHM3/87A?
The SE40PBHM3/87A has a typical junction-to-mount thermal resistance of 6.6 °C/W when mounted on a 14 mm × 14 mm, 2 oz. FR4 PCB. This value is measured per JEDEC standards and enables accurate thermal modeling for automotive modules where direct thermal coupling to the PCB is the primary heat dissipation path.
Is SE40PBHM3/87A compatible with lead-free reflow soldering processes?
Yes, SE40PBHM3/87A is rated MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102, ensuring reliable wetting and intermetallic formation in standard lead-free SAC305 profiles without preconditioning or dry-pack requirements.
