Product details
Overview
HS3DBH from Taiwan Semiconductor is a 200 V, 3 A surface-mount high-efficiency fast recovery rectifier in DO-214AA (SMB) package, featuring 50 ns reverse recovery time, 1.0 V forward voltage at 3 A, and AEC-Q101 qualification for automotive use in DC-DC converters and freewheeling circuits.
For engineers reviewing the HS3DBH datasheet, HS3DBH pinout, HS3DBH application, or HS3DBH equivalent, key selection criteria include repetitive peak reverse voltage (200 V), surge current capability (100 A), junction-to-ambient thermal resistance (60 °C/W), low-profile SMB packaging, and automotive-grade reliability per AEC-Q101.
Technical Context
The HS3DBH is a single-die, glass-passivated silicon rectifier optimized for high-frequency switching applications. Its 50 ns trr and 1.0 V VF at 3 A enable reduced conduction and switching losses in compact power supplies.
Designed for automated SMT assembly, it meets J-STD-002 solderability, JESD 201 Class 2 whisker resistance, and moisture sensitivity level 1. Polarity is marked by cathode band on the DO-214AA case.
Key Specifications

| VF @ 3 A | 1.0 V - Forward voltage drop defining conduction loss and thermal dissipation in continuous operation |
| RθJA | 60 °C/W - Junction-to-ambient thermal resistance with standard JEDEC 2s2p pad layout; determines heatsinking requirements |
| TJ max | +150 °C - Maximum allowable junction temperature; sets upper limit for ambient + power loss derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EWH02-M3/45 | 200 V VRRM, 3 A IF, 55 ns trr, same DO-214AA package, but not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial/commercial power only | Select when AEC-Q101 is not required and Vishay supply chain preference applies |
| ON Semiconductor MUR320G | 200 V VRRM, 3 A IF, 75 ns trr, TO-220AC package (through-hole), AEC-Q101 qualified | Through-hole mounting; higher thermal mass but incompatible with SMT-only lines | Select when legacy through-hole assembly or higher surge margin (125 A IFSM) is prioritized over board space |
Compared with VS-3EWH02-M3/45 and MUR320G, the HS3DBH uniquely combines AEC-Q101 qualification, DO-214AA SMT compatibility, and 50 ns trr-making it optimal for space-constrained, high-frequency automotive power stages where both reliability and switching efficiency are critical.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HS3DBH?
The HS3DBH has a VRRM rating of 200 V, meaning it can reliably block up to 200 V of reverse voltage in repetitive operation without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official TSC datasheet (Version A2102) and defines the upper limit for safe reverse-bias operation in applications like snubbers and output rectification.
Is HS3DBH qualified for automotive applications?
Yes, HS3DBH is explicitly AEC-Q101 qualified per the manufacturer's documentation. It undergoes stress testing for temperature cycling, humidity, mechanical shock, and other automotive environmental conditions, making it suitable for under-hood and cabin applications including DC-DC converters and LED drivers in passenger vehicles and commercial fleets.
What is the forward voltage drop (VF) of HS3DBH at rated current?
The HS3DBH exhibits a typical forward voltage drop of 1.0 V at 3 A and 25°C junction temperature, as specified in the Electrical Specifications table. This low VF directly reduces conduction losses and improves thermal efficiency in high-current rectification paths, especially in compact automotive power modules.
What package type does HS3DBH use, and is it RoHS compliant?
HS3DBH uses the DO-214AA (SMB) surface-mount package with matte tin-plated leads and is fully RoHS compliant and halogen-free per IEC 61249-2-21. The package features a low profile (2.6 mm height), UL 94V-0 molding compound, and meets J-STD-002 solderability and JESD 201 Class 2 whisker resistance standards.
What is the reverse recovery time (trr) of HS3DBH, and why does it matter?
The HS3DBH has a reverse recovery time of 50 ns under standard test conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A). This fast trr minimizes switching losses and voltage overshoot during turn-off, enabling efficient operation in high-frequency DC-DC converters (up to ~500 kHz) and reducing EMI generation in sensitive automotive systems.
