Product details
Overview
S1PGHM3/84A from Vishay General Semiconductor is an automotive-grade, glass passivated surface-mount silicon rectifier diode in the eSMP® SMP (DO-220AA) package, rated for 400 V repetitive peak reverse voltage (VRRM), 1.0 A average forward current (IF(AV)), and 0.95 V forward voltage at 1.0 A and 125 °C - used for polarity and rail-to-rail protection in automotive power rails.
For engineers reviewing the S1PGHM3/84A datasheet, S1PGHM3/84A pinout, S1PGHM3/84A application, or S1PGHM3/84A equivalent, key selection criteria include its AEC-Q101 qualification, MSL level 1 rating, 1.0 mm profile, 150 °C max junction temperature, and automotive-grade whisker test compliance (JESD 201 Class 2).
Technical Context
This device is a single, unidirectional, standard recovery rectifier with glass-passivated junction construction, optimized for low thermal resistance (RθJL = 15 °C/W) and high current density in space-constrained PCB layouts. Its 1.8 µs typical reverse recovery time (trr) and 6.0 pF junction capacitance support moderate-speed switching in DC power conditioning circuits.
The S1PGHM3/84A operates across –55 °C to +150 °C and maintains ≤1 µA reverse leakage at 25 °C and ≤100 µA at 125 °C under rated VR, enabling reliable operation in under-hood automotive environments where thermal stability and leakage control are critical.
Key Specifications

FAQ
What is the maximum junction temperature rating for the S1PGHM3/84A?
The S1PGHM3/84A has a maximum junction temperature (TJ) of +150 °C, verified per AEC-Q101 stress testing. This rating enables reliable operation in under-hood automotive environments where ambient temperatures exceed 105 °C. The device's thermal resistance (RθJL = 15 °C/W) ensures that at 1.0 A IF(AV), junction temperature rise remains within specification when mounted on a 5.0 mm × 5.0 mm copper pad.
Is the S1PGHM3/84A suitable for lead-free reflow soldering?
Yes, the S1PGHM3/84A is rated MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C, making it fully compatible with standard lead-free soldering processes. Its matte tin-plated terminals meet J-STD-002 and JESD 22-B102 solderability requirements, and the molding compound complies with UL 94 V-0 flammability standards.
How does the S1PGHM3/84A differ from the commercial-grade S1PG-M3/84A?
The S1PGHM3/84A is the automotive-grade variant: it carries the "HM3" suffix indicating halogen-free, RoHS-compliant construction with JESD 201 Class 2 whisker resistance and full AEC-Q101 qualification. In contrast, the S1PG-M3/84A ("M3") is commercial grade, meeting only JESD 201 Class 1A and lacking automotive stress validation - both share identical electrical specs and SMP package dimensions.
What is the reverse leakage current of the S1PGHM3/84A at elevated temperature?
At 125 °C and rated VR (400 V), the S1PGHM3/84A exhibits a maximum reverse leakage current (IR) of 100 µA, per datasheet specifications. At 25 °C and 400 V, leakage is ≤1.0 µA. This low, well-characterized leakage supports stable biasing in precision analog front-ends and prevents excessive standby power loss in always-on automotive subsystems.
Does the S1PGHM3/84A have a defined pinout orientation for automated placement?
Yes - the S1PGHM3/84A uses the SMP (DO-220AA) package with a visible cathode band marking one end. During automated placement, the band aligns with the cathode pad on the PCB footprint. The anode is the opposite terminal. The device is symmetric in width but asymmetric in marking, ensuring unambiguous orientation in pick-and-place programs and optical recognition systems.
