Product details
Overview
HS3BH from Taiwan Semiconductor is a 3A, 100V AEC-Q101-qualified surface-mount rectifier in DO-214AB (SMC) package, featuring 1.0V forward voltage at 3A/25°C, 150A peak surge current, and 50ns reverse recovery time - deployed in automotive DC-DC converters and freewheeling circuits.
For engineers reviewing the HS3BH datasheet, HS3BH pinout, HS3BH application, or HS3BH equivalent, key selection criteria include its 100V repetitive peak reverse voltage, low-profile SMC package compatibility with automated placement, moisture sensitivity level 1 rating, and junction temperature range of –55°C to +150°C.
Technical Context
The HS3BH is a single-die, glass-passivated silicon rectifier optimized for high-efficiency switching applications. Its 50ns reverse recovery time and 1.0V forward voltage at rated current support reduced switching losses in high-frequency DC-DC topologies.
Designed for automotive-grade reliability, it meets AEC-Q101 stress testing requirements and features matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance - critical for under-hood and lighting control modules.
Key Specifications

| IF | 3 A continuous - average forward current rating at TA = 75°C; supports compact thermal design in space-constrained automotive PCBs |
| IFSM | 150 A - non-repetitive surge capability for inrush and fault transient handling without device failure |
| VF @ 3A, 25°C | 1.0 V - low conduction loss enabling >92% efficiency in 12V–48V DC-DC stages |
| trr | 50 ns - fast recovery minimizes reverse recovery charge (Qrr), reducing EMI and diode switching losses |
| TJ max | +150 °C - extended junction temperature enables operation near power semiconductors in engine control units |
| RθJA | 60 °C/W - thermal resistance value used to calculate heatsink-free operation up to ~1.8W dissipation at 75°C ambient |
Pinout & Package

Applications
| Automotive DC-DC Converter | LED Headlamp Freewheeling |
|---|---|
Use Scenario: Step-down conversion from 12V battery to 5V/3.3V for microcontrollers and sensors in body control modules. IC Role / Device Role / Timing Role: Output rectifier in synchronous or quasi-resonant buck topology; handles continuous 3A load with minimal conduction loss. Use Value: 1.0V VF reduces power loss by ≥0.3W vs. legacy 1.3V diodes, lowering thermal stress on adjacent gate drivers. | Use Scenario: Freewheeling path for high-side LED driver ICs powering adaptive front-lighting systems. IC Role / Device Role / Timing Role: Provides low-loss current recirculation during PWM off-time; fast 50ns trr prevents LED current droop and flicker. Use Value: 50ns recovery ensures clean current commutation at 2kHz–10kHz PWM frequencies, preserving beam pattern stability. |
| Snubber Network in Ignition Coil Driver | Reverse Polarity Protection in Rear Camera Module |
Use Scenario: RC snubber across MOSFET drain-source in 48V starter-generator control circuits. IC Role / Device Role / Timing Role: Clamps voltage spikes during turn-off; absorbs energy from leakage inductance with minimal delay. Use Value: 100V VRRM withstands transient spikes up to 120V; 50ns trr ensures snubber activation within <100ns of MOSFET turn-off. | Use Scenario: Input protection for 5V camera power rail exposed to reverse battery connection during service. IC Role / Device Role / Timing Role: Series-blocking rectifier placed before LDO regulator; conducts only during correct polarity. Use Value: 3A IF rating supports full camera module startup surge; 150A IFSM survives accidental 12V reverse connection with fuse coordination. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EWH10-M3/45 | Same DO-214AB package, 3A/100V, VF = 1.05V @ 3A, trr = 50ns, AEC-Q101 qualified | Identical automotive use cases; slightly higher VF increases conduction loss by ~0.015W | Preferred where Vishay supply chain alignment is required; identical thermal and layout footprint |
| ON Semiconductor MUR310S | DO-214AB, 3A/100V, VF = 0.95V @ 3A, trr = 75ns, no AEC-Q101 certification | Acceptable for industrial DC-DC but not automotive qualified systems; slower recovery increases EMI risk above 500kHz | Select only for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with VS-3EWH10-M3/45 and MUR310S, the HS3BH delivers identical surge robustness and thermal performance while maintaining AEC-Q101 compliance - making it the preferred choice for automotive-grade designs requiring zero qualification overhead and proven field reliability.

FAQ
What is the maximum junction temperature rating for HS3BH?
The HS3BH has a maximum junction temperature (TJ max) of +150°C, verified per AEC-Q101 thermal cycling and high-temperature operating life tests. This allows reliable operation adjacent to power MOSFETs in engine control units. The HS3BH must be derated linearly above 75°C ambient per the forward current derating curve in the official TSC datasheet revision A2102.
Is HS3BH pin-compatible with other devices in the HS3xH series?
Yes - all HS3xH devices including HS3BH share identical DO-214AB (SMC) package dimensions, anode/cathode terminal layout, and polarity marking. Mechanical and soldering compatibility is guaranteed across the series; only VRRM, VF, and trr differ between variants. The HS3BH maintains full board-level interchangeability with HS3AH, HS3DH, and others when voltage and recovery requirements align.
Does HS3BH require baking before reflow soldering?
No - the HS3BH is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH without baking. This eliminates pre-reflow bake steps in SMT lines, reducing process time and avoiding potential lead oxidation. The HS3BH's matte tin plating also ensures solderability per J-STD-002 without flux enhancement.
What is the reverse recovery time (trr) specification for HS3BH?
The HS3BH has a maximum reverse recovery time (trr) of 50 ns, measured at IF = 0.5A, IR = 1.0A, and Irr = 0.25A per JEDEC test conditions. This fast recovery enables efficient operation in 200–1000 kHz switching converters. The HS3BH's trr remains stable across –40°C to +125°C junction temperature, supporting consistent timing in automotive ambient ranges.
Can HS3BH be used in reverse polarity protection circuits?
Yes - the HS3BH is routinely deployed as a series input rectifier for reverse polarity protection in automotive camera and infotainment modules. With 3A continuous rating and 150A IFSM, it safely blocks reverse battery connections while passing full load current forward. Its 100V VRRM provides margin against load dump transients, and the HS3BH's low VF minimizes voltage drop in the protected rail.
