Product details
Overview
HS3MH from Taiwan Semiconductor is a 1000V, 3A surface-mount high-efficiency rectifier diode in DO-214AB (SMC) package, featuring 1.7V forward voltage at 3A, 75ns reverse recovery time, and AEC-Q101 qualification for automotive use in freewheeling and snubber circuits.
For engineers reviewing the HS3MH datasheet, HS3MH pinout, HS3MH application, or HS3MH equivalent, key selection criteria include peak reverse voltage rating (1000V), thermal resistance (60°C/W), junction capacitance (50pF), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
The HS3MH is a single-die, glass-passivated silicon rectifier optimized for high-voltage switching applications. Its 1000V VRRM, 150A IFSM, and 75ns trr support fast transient handling in DC-DC converters and automotive power stages.
Thermal performance is defined by RθJA = 60°C/W and TJ(max) = 150°C, with cathode-band polarity marking and matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - maximum repetitive reverse voltage; defines safe blocking capability in high-voltage DC bus or snubber networks |
| IF | 3 A - continuous forward current rating; supports steady-state conduction in 12–48V automotive power rails |
| trr | 75 ns - reverse recovery time at IF=0.5A/IR=1.0A; enables efficient operation in 100kHz+ switching topologies |
| VF | 1.7 V @ 3A, 25°C - forward voltage drop; determines conduction loss and thermal load under full rated current |
| CJ | 50 pF @ 1MHz, 4V - junction capacitance; impacts high-frequency switching noise and EMI in flyback/snubber circuits |
| RθJA | 60 °C/W - junction-to-ambient thermal resistance; defines required PCB copper area and airflow for thermal management |
| IFSM | 150 A - non-repetitive surge current (8.3ms half-sine); withstands inrush and fault currents in automotive lighting and motor drives |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EWH10 | Same DO-214AB package, 1000V VRRM, but 1.35V VF @ 3A and 50ns trr; not AEC-Q101 qualified | Better efficiency in high-frequency SMPS; unsuitable for automotive qualification-critical designs | Select when lower conduction loss and faster recovery outweigh automotive compliance requirements |
| ON Semiconductor MUR3100CT | TO-220AC package, dual common-cathode configuration, 1000V, 3A per die; 1.75V VF, 75ns trr; AEC-Q101 qualified | Requires through-hole mounting and larger board area; suited for higher thermal mass or dual-output systems | Select when board-level thermal design permits TO-220 and dual-diode functionality is needed |
Compared with VS-3EWH10 and MUR3100CT, the HS3MH uniquely combines AEC-Q101 qualification, DO-214AB SMT compatibility, and 1000V/3A rating in a single-die, halogen-free construction-making it optimal for space- and compliance-constrained automotive surface-mount power stages.

FAQ
What is the maximum junction temperature rating for HS3MH?
The HS3MH has a maximum junction temperature (TJ(max)) of +150°C, validated per AEC-Q101 stress testing. This rating allows continuous operation in under-hood automotive environments when mounted on adequate copper area and within its 60°C/W thermal resistance limit. Derating curves in the HS3MH datasheet confirm usable current capacity down to 0A at 150°C ambient with zero airflow.
Is HS3MH compatible with lead-free reflow soldering processes?
Yes, the HS3MH uses matte tin-plated leads compliant with J-STD-002 solderability standards and is rated for lead-free reflow profiles up to 260°C peak temperature. Its J-STD-020 moisture sensitivity level is Level 1, meaning no pre-bake is required prior to assembly-reducing process complexity and eliminating popcorning risk during reflow.
Does HS3MH have automotive qualification?
Yes, the HS3MH is AEC-Q101 qualified, having passed all required stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress test (uHAST). This qualification confirms suitability for automotive power electronics such as lighting drivers, body control modules, and DC-DC converters where reliability over 15 years is mandated.
What is the reverse leakage current specification for HS3MH at elevated temperature?
At TJ = 125°C and rated VR, the HS3MH exhibits a maximum reverse leakage current (IR) of 250 µA, measured under 30ms pulse conditions. This value is critical for snubber and hold-up capacitor discharge paths where low standby loss is required across wide temperature ranges in automotive applications.
How does the junction capacitance of HS3MH affect high-frequency circuit performance?
The HS3MH has a typical junction capacitance (CJ) of 50 pF at 1 MHz and 4.0 V reverse bias. This low capacitance minimizes displacement current and EMI generation during fast voltage transitions-especially important in 100–500 kHz DC-DC converters and IGBT snubbers where parasitic ringing must be suppressed without adding external damping components.
