Product details
Overview
SE20PDHM3/85A from Vishay General Semiconductor is an AEC-Q101-qualified surface-mount ultra-low-profile ESD-capable rectifier in SMP (DO-220AA) package, rated for 200 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 - used for rail-to-rail and polarity protection in automotive power rails.
For engineers reviewing the SE20PDHM3/85A datasheet, SE20PDHM3/85A pinout, SE20PDHM3/85A application, or SE20PDHM3/85A equivalent, key selection criteria include its 175 °C max junction temperature, 1.2 μs typical reverse recovery time, 13 pF junction capacitance, MSL Level 1 rating, and automotive-grade HM3 suffix with JESD 201 Class 2 whisker resistance.
Technical Context
This device is a single silicon planar junction rectifier optimized for high-reliability automotive applications. It features oxide planar chip construction, low forward voltage drop, and integrated ESD immunity per AEC-Q101-001 Human Body Model (HBM) Class H3B (>8 kV contact discharge).
Thermally, it delivers RθJM = 20 °C/W (junction-to-mount) on 5.0 mm × 5.0 mm 2 oz. FR4 PCB, enabling robust thermal management in space-constrained modules. Its 1.0 mm typical height and DO-220AA footprint support automated placement in high-volume automotive electronics assembly.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SE20PD-M3/85A | Commercial-grade M3 suffix; JESD 201 Class 1A whisker test; same electrical specs and package | Lacks AEC-Q101 qualification and automotive traceability; not approved for under-hood use | Select when cost-sensitive industrial or consumer designs do not require automotive qualification |
| ON Semiconductor NRVB20200CTT4G | TO-220AC package; dual common-cathode configuration; 200 V VRRM, 10 A total IF(AV); higher VF (0.95 V @ 10 A) | Requires larger board area and heat sinking; suited for higher-current, non-automotive power supplies | Choose only if higher current capacity and through-hole mounting are required; not drop-in compatible |
Compared with SE20PDHM3/85A, the SE20PD-M3/85A offers identical performance in non-automotive settings but lacks AEC-Q101 validation, while the NRVB20200CTT4G provides higher current capability in a physically incompatible TO-220 package - making SE20PDHM3/85A the sole fit for space-constrained, thermally aggressive automotive rectification where qualification and profile height are decisive.

FAQ
What is the maximum junction temperature rating for SE20PDHM3/85A?
The SE20PDHM3/85A has a maximum junction temperature (TJ) of 175 °C, verified per AEC-Q101 stress testing. This rating allows uninterrupted operation in under-hood automotive environments and high-ambient industrial enclosures without thermal derating up to that limit. The device's RθJM of 20 °C/W further supports sustained performance when mounted on adequate copper area.
Does SE20PDHM3/85A meet AEC-Q101 requirements?
Yes, SE20PDHM3/85A is fully AEC-Q101 qualified, as confirmed in Vishay document 87905 (Revision: 16-Jun-2023). Qualification covers temperature cycling, high-temperature operating life, humidity bias, and ESD (HBM Class H3B >8 kV), making it suitable for automotive powertrain, body control, and ADAS modules.
What does the 'HM3' suffix indicate in SE20PDHM3/85A?
The 'HM3' suffix denotes automotive-grade construction: halogen-free, RoHS-compliant materials plus JESD 201 Class 2 whisker resistance on matte tin terminations. It distinguishes SE20PDHM3/85A from commercial 'M3' variants and confirms compliance with automotive reliability and material standards beyond basic electrical specs.
Is SE20PDHM3/85A compatible with lead-free reflow processes?
Yes, SE20PDHM3/85A is rated for lead-free reflow with a maximum peak temperature of 260 °C per J-STD-020 MSL Level 1. Its molding compound meets UL 94 V-0, and terminals are solderable per J-STD-002 and JESD 22-B102 - supporting standard Pb-free SAC305 profiles without preconditioning.
What is the reverse recovery time (trr) of SE20PDHM3/85A and how is it measured?
The SE20PDHM3/85A has a typical reverse recovery time (trr) of 1.2 μs, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery supports efficient operation in moderate-frequency protection circuits and helps suppress voltage spikes during commutation in power rail conditioning networks.
