Product details
Overview
S1JHM3_A/H from Vishay General Semiconductor is a surface-mount glass passivated silicon rectifier diode in SMA (DO-214AC) package, rated for 600 V maximum recurrent peak reverse voltage (VRRM), 1.0 A average forward rectified current (IF(AV)), and 1.1 V forward voltage drop at 1.0 A. It features low leakage (1.0 μA at 25 °C), high surge capability (30 A IFSM), and AEC-Q101 qualification for automotive applications.
For engineers reviewing the S1JHM3_A/H datasheet, S1JHM3_A/H pinout, S1JHM3_A/H application, or S1JHM3_A/H equivalent, key selection criteria include its halogen-free RoHS-compliant construction, MSL Level 1 rating (260 °C peak reflow), 175 °C max junction temperature, and cathode-band polarity marking - critical for power supply rectification, freewheeling, and DC/DC converter designs.
Technical Context
The S1JHM3_A/H is a single-junction, unidirectional silicon rectifier optimized for general-purpose AC-to-DC conversion and flyback energy recovery. Its glass-passivated chip ensures stable reverse characteristics and robust thermal performance up to 175 °C junction temperature.
Designed for automated SMT placement, it uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets JESD 201 Class 2 whisker resistance. The SMA package provides low profile and UL 94 V-0 flammability compliance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB160-E3/5AT | 60 V VRRM, 1.0 A IF(AV), 1.0 V VF, SMA package, commercial grade (not AEC-Q101) | Limited to low-voltage DC/DC and USB-powered devices; unsuitable for AC line or automotive environments | Select when cost sensitivity outweighs voltage margin and automotive qualification needs |
| ES1J-M3/5AT | 600 V VRRM, 1.0 A IF(AV), 1.7 V VF, faster trr (35 ns), SMA package, commercial grade | Better for high-frequency PFC or synchronous rectifier replacement; higher VF increases conduction loss | Prefer where fast switching dominates over thermal efficiency; verify layout thermal relief for 1.7 V drop |
Compared with SB160-E3/5AT and ES1J-M3/5AT, the S1JHM3_A/H uniquely combines 600 V rating, AEC-Q101 qualification, halogen-free compliance, and 1.1 V VF - making it the only choice for thermally demanding, automotive-qualified, and environmentally regulated 600 V rectification tasks.

FAQ
What is the maximum junction temperature rating for the S1JHM3_A/H?
The S1JHM3_A/H has a maximum junction temperature (TJ max.) of 175 °C, enabling reliable operation in high-ambient environments such as under-hood automotive locations or sealed industrial enclosures. This rating is validated per the Vishay datasheet Document Number 88711 and supports derating curves up to that limit. Thermal design must account for RθJA = 85 °C/W when mounted on standard 0.2" × 0.2" copper pads.
Is the S1JHM3_A/H qualified for automotive applications?
Yes, the S1JHM3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HM3" and documentation in datasheet 88711. This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - making the S1JHM3_A/H suitable for automotive body electronics, infotainment power supplies, and ADAS auxiliary rails.
What does the "HM3" suffix mean in S1JHM3_A/H?
The "HM3" suffix in S1JHM3_A/H indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification. "H" denotes the tape-and-reel packaging format (1800 units per 7" reel), and "M3" specifies the halogen-free, environmentally compliant material set - distinct from "E3" (RoHS-compliant only) and "HE3" (AEC-Q101 + RoHS). This is defined in Vishay's ordering information table on page 2 of document 88711.
What is the reverse leakage current specification for the S1JHM3_A/H at 125 °C?
At TJ = 125 °C and rated DC blocking voltage, the S1JHM3_A/H exhibits a maximum DC reverse current (IR) of 50 μA, per the Electrical Characteristics table in Vishay datasheet 88711. This value is critical for estimating standby power loss in high-temperature applications such as industrial motor drives or telecom base station power supplies where thermal management is constrained.
Does the S1JHM3_A/H have a specified reverse recovery time (trr)?
Yes, the S1JHM3_A/H has a typical reverse recovery time (trr) of 1.8 μs, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is published in the Electrical Characteristics section of Vishay's datasheet 88711 and confirms suitability for switching frequencies up to ~100 kHz in flyback and forward converter topologies without excessive switching loss or EMI concerns.
