Product details
Overview
HS3DH from Taiwan Semiconductor is a 3A, 200V repetitive peak reverse voltage (VRRM) surface-mount high-efficiency rectifier in DO-214AB (SMC) package, featuring 1.0 V max forward voltage at 3 A and 50 ns reverse recovery time - deployed in automotive lighting and DC-DC converter freewheeling paths.
For engineers reviewing the HS3DH datasheet, HS3DH pinout, HS3DH application, or HS3DH equivalent, key selection criteria include its AEC-Q101 qualification, glass-passivated junction, moisture sensitivity level 1 rating, 150 A IFSM surge capability, and DO-214AB thermal resistance of 60 °C/W.
Technical Context
This device is a single-die, standard recovery silicon rectifier optimized for high-current switching applications where low VF and fast trr reduce conduction and switching losses. Its junction-to-ambient thermal resistance (60 °C/W) and 150 °C maximum junction temperature support sustained operation under automotive ambient conditions.
The HS3DH operates with a rated IF of 3 A DC, withstands 200 V repetitive reverse voltage, and exhibits 10 µA max reverse leakage at 25 °C - enabling reliable blocking in snubber and flyback clamp circuits without thermal runaway risk.
Key Specifications

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 | Same DO-214AB package, 200 V VRRM, but 1.15 V VF (max @ 3 A) and 75 ns trr | Higher conduction loss and slower recovery limit use in >200 kHz designs | Acceptable where thermal margin exists and switching frequency <150 kHz |
| ON Semiconductor MUR320G | TO-220AC package, 200 V VRRM, 1.25 V VF, 75 ns trr, no AEC-Q101 qualification | Requires through-hole mounting and lacks automotive qualification | Suitable for industrial non-automotive use with higher thermal mass requirements |
Compared with VS-3EWH02-M3/45 and MUR320G, the HS3DH delivers lower forward drop and faster recovery in an AEC-Q101-qualified SMT package - making it preferred for space-constrained, high-frequency automotive power stages requiring zero rework risk.

FAQ
What is the maximum junction temperature rating for HS3DH?
The HS3DH has a maximum junction temperature (TJ) of +150 °C, validated per AEC-Q101 stress testing. This rating allows continuous operation in under-hood automotive environments when mounted on a PCB with ≥1 in² copper area. Derating begins above 25 °C ambient, and the device must not exceed 150 °C junction temperature under worst-case power dissipation - a condition verified using its 60 °C/W RθJA and measured VF/IF characteristics. HS3DH thermal performance is documented in TSC Version A2102 datasheet Section 2.
Is HS3DH pin-compatible with other parts in the HS3xH series?
Yes, all HS3xH devices - including HS3AH, HS3BH, HS3DH, and up to HS3MH - share identical DO-214AB (SMC) package dimensions, lead pitch, and pinout (anode/cathode orientation). The only differences are VRRM rating and associated electrical parameters like VF and trr. Therefore, HS3DH can be substituted within the same footprint for designs requiring 200 V blocking, provided layout thermal design and surge margins remain appropriate. HS3DH marking code is "HS3D".
Does HS3DH meet automotive reliability standards?
Yes, HS3DH is explicitly qualified to AEC-Q101 Rev D for discrete semiconductors, covering stress tests including HTGB, HTRB, uHAST, temperature cycling, and mechanical shock. It also complies with JESD201 Class 2 whisker testing and carries moisture sensitivity level 1 per J-STD-020 - eliminating bake requirements prior to reflow. These qualifications are confirmed in the official Taiwan Semiconductor HS3xH datasheet Version A2102, page 1.
What is the reverse recovery time (trr) specification for HS3DH?
The HS3DH has a maximum reverse recovery time (trr) of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC test conditions. This value is confirmed in the Electrical Specifications table of the HS3xH datasheet (Version A2102, page 2). The 50 ns trr enables efficient operation in switching power supplies operating up to 500 kHz while minimizing switching loss and voltage overshoot.
Can HS3DH be used in surface-mount reflow processes without special handling?
Yes, HS3DH is rated moisture sensitivity level 1 (MSL-1) per J-STD-020, meaning it may be stored indefinitely at ≤30 °C/60% RH and subjected to standard Pb-free reflow profiles (e.g., IPC/JEDEC J-STD-020D peak 260 °C) without baking. Its matte tin-plated leads ensure solderability per J-STD-002, and the DO-214AB body meets UL 94V-0 flammability. No preconditioning or dry-pack handling is required for HS3DH - simplifying SMT line integration.
