Product details
Overview
RS3DH from Taiwan Semiconductor is a 200 V, 3 A fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 150 ns reverse recovery time, 100 A peak surge current, and AEC-Q101 qualification for automotive-grade reliability-used in DC-DC converters and snubber circuits.
For engineers reviewing the RS3DH datasheet, RS3DH pinout, RS3DH application, or RS3DH equivalent, key selection criteria include repetitive peak reverse voltage (200 V), forward voltage at 3 A (≤1.3 V), junction temperature range (–55°C to +175°C), thermal resistance (RθJL = 15°C/W), and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
The RS3DH employs a glass-passivated single-die silicon junction optimized for fast switching and high-efficiency power conversion. Its 150 ns trr and low VF support high-frequency operation in flyback and boost topologies while maintaining robust surge handling (IFSM = 100 A).
Designed for automotive and industrial environments, it meets AEC-Q101 stress testing requirements and features 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 | 200 V - Maximum non-repetitive reverse blocking voltage; defines safe operating limit in high-voltage DC-DC stages |
| IF | 3 A - Continuous average forward current at TL = 75°C; determines steady-state power handling capability |
| trr | 150 ns - Measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables >1 MHz switching in snubbers and SMPS |
| VF @ 3 A | ≤1.3 V - Forward voltage drop at rated current and 25°C; directly impacts conduction loss and thermal design |
| RθJL | 15 °C/W - Junction-to-lead thermal resistance; supports direct heatsinking via PCB copper pour or metal-core board |
| TJ max | +175 °C - Maximum junction temperature; allows operation in under-hood automotive environments without derating |
| MSL | Level 1 - No floor life limitation before reflow; eliminates bake requirements for SMT assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EWH02-M3/45 | 200 V VRRM, 3 A IF, 120 ns trr, DO-214AB, but not AEC-Q101 qualified | Suitable for commercial/industrial DC-DC; lacks automotive stress validation | Select when AEC-Q101 is not required and faster recovery is prioritized |
| ON Semiconductor MUR320G | 200 V VRRM, 3 A IF, 75 ns trr, TO-220AC package (through-hole), AEC-Q101 qualified | Requires through-hole assembly; superior speed but larger footprint and no SMT compatibility | Select when ultra-low trr is critical and board space/layout flexibility permits TO-220 mounting |
Compared with VS-3EWH02-M3/45 and MUR320G, the RS3DH uniquely balances AEC-Q101 compliance, SMT-ready DO-214AB packaging, and 150 ns recovery-making it optimal for automotive SMT power stages where qualification, size, and speed must coexist.

FAQ
What is the maximum junction temperature rating for RS3DH?
The RS3DH has a maximum junction temperature (TJ) of +175°C, verified per AEC-Q101 stress testing. This rating allows reliable operation in under-hood automotive environments and high-ambient industrial settings without additional derating beyond the published forward current derating curve. The RS3DH maintains electrical performance stability up to this limit when thermal design adheres to RθJL = 15°C/W specifications.
Is RS3DH pin-compatible with other devices in the RS3xH series?
Yes, all RS3xH devices-including RS3AH, RS3BH, RS3DH, RS3GH, RS3JH, RS3KH, and RS3MH-share identical DO-214AB (SMC) package dimensions, pinout, and thermal pad layout. The only functional difference is VRRM, ranging from 50 V to 1000 V; thus, RS3DH can be substituted within the same footprint when 200 V blocking is required.
Does RS3DH require special handling during PCB assembly?
No-RS3DH is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and does not require dry pack or baking prior to reflow. Its matte tin-plated leads comply with J-STD-002 for solderability, and the DO-214AB package supports standard lead-free reflow profiles. The RS3DH is fully compatible with automated SMT lines used for automotive-grade production.
What is the reverse recovery time (trr) specification for RS3DH, and how is it measured?
The RS3DH has a reverse recovery time (trr) of 150 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A at TJ = 25°C. This value is confirmed in the official Taiwan Semiconductor datasheet Version B2304 and reflects actual switching behavior in high-frequency snubber and converter applications. The RS3DH's trr is consistent across its operating temperature range.
Can RS3DH replace older rectifiers like 1N5408 in existing designs?
RS3DH can replace 1N5408 in SMT-based upgrades where DO-214AB footprint is adopted, but not as a direct drop-in for through-hole 1N5408 (DO-201AD). While both are 3 A rectifiers, RS3DH offers superior speed (150 ns vs. ~2000 ns), higher VRRM tolerance (200 V vs. 1000 V), and AEC-Q101 qualification. For legacy through-hole boards, consider TO-220 alternatives like MUR320G instead of RS3DH.
