Product details
Overview
HS3BBH from Taiwan Semiconductor is a 3A, 100V AEC-Q101-qualified surface-mount Schottky rectifier in DO-214AA (SMB) package, featuring 1.0V max forward voltage at 3A, 50ns reverse recovery time, and 80pF junction capacitance - deployed in automotive DC-DC converters and car lighting freewheeling circuits.
For engineers reviewing the HS3BBH datasheet, HS3BBH pinout, HS3BBH application, or HS3BBH equivalent, key selection criteria include repetitive peak reverse voltage (100V), surge current rating (100A), thermal resistance (60°C/W), junction temperature range (–55°C to +150°C), and RoHS/halogen-free compliance for automotive-grade reliability.
Technical Context
This device is a single-die, glass-passivated silicon planar junction rectifier optimized for fast switching and low conduction loss. Its 100V VRRM, 3A average forward current, and 100A non-repetitive surge capability support high-efficiency power conversion in constrained layouts.
The DO-214AA (SMB) package enables automated placement with matte tin-plated leads compliant to J-STD-002, while moisture sensitivity level 1 (per J-STD-020) ensures robust reflow compatibility without dry-pack requirements.
Key Specifications

| IF | 3 A - continuous forward current handling for mid-power DC-DC stages |
| IFSM | 100 A - withstands 8.3ms half-sine surge transients common in automotive load dumps |
| VF @ 3A, 25°C | ≤1.0 V - minimizes conduction loss and self-heating in high-duty-cycle operation |
| trr | ≤50 ns - enables high-frequency switching (>100 kHz) with low switching loss |
| RθJA | 60 °C/W - limits junction temperature rise under 3A load on standard 1-in² copper pad |
| Junction temp | –55°C to +150°C - supports under-hood automotive environments and industrial ambient extremes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EWH01-M3/5AT | Same DO-214AA package, 100V VRRM, but 1.1V VF @ 3A and 75ns trr | Slightly higher conduction loss and slower recovery limit use in >200kHz designs | Acceptable where thermal budget allows +0.1V VF penalty and lower switching frequency is used |
| ON Semiconductor MUR310HE3/45 | Higher 1000V VRRM, 50ns trr, but 1.3V VF @ 3A and TO-220AC package | Larger footprint and higher VF reduce efficiency in space-constrained automotive modules | Only suitable when higher voltage margin is required and board area permits through-hole mounting |
Compared with VS-3EWH01-M3/5AT and MUR310HE3/45, HS3BBH delivers the lowest forward voltage (≤1.0V) in its voltage class within the compact DO-214AA package, making it optimal for thermally dense automotive DC-DC and LED driver designs requiring both efficiency and AEC-Q101 compliance.

FAQ
What is the maximum repetitive peak reverse voltage rating for HS3BBH?
The HS3BBH has a maximum repetitive peak reverse voltage (VRRM) of 100 V, verified per the manufacturer's A2102 datasheet revision. This rating defines the highest reverse voltage the device can block continuously without avalanche breakdown. Engineers must ensure system-level transient voltages remain below this value, including safety margins for ringing and overshoot in automotive applications.
Is HS3BBH qualified for automotive use?
Yes, HS3BBH is AEC-Q101 qualified, meaning it has passed standardized stress tests for temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. This qualification confirms suitability for automotive power electronics such as body control modules and lighting drivers where reliability under thermal and vibration stress is critical.
What is the forward voltage drop of HS3BBH at 3A and 25°C?
The HS3BBH exhibits a maximum forward voltage drop (VF) of 1.0 V at 3 A and junction temperature of 25°C, as specified in the electrical characteristics table. This low VF directly reduces conduction losses and improves overall efficiency in high-current DC-DC and LED driver applications.
Does HS3BBH have a defined reverse recovery time?
Yes, HS3BBH has a maximum reverse recovery time (trr) of 50 ns under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery supports high-frequency switching topologies and minimizes switching losses and EMI generation in automotive power supplies.
What package type does HS3BBH use, and is it compatible with standard SMT processes?
HS3BBH uses the DO-214AA (SMB) surface-mount package with matte tin-plated leads compliant to J-STD-002. Its moisture sensitivity level is 1 (per J-STD-020), eliminating pre-bake requirements. The package is fully compatible with standard reflow profiles and automated pick-and-place equipment used in automotive electronics manufacturing.
