Product details
Overview
S3DH from Taiwan Semiconductor is a 3A, 200V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring low forward voltage drop (max 1.15 V at 3 A), high surge current capability (100 A @ 8.3 ms), and AEC-Q101 qualification for automotive use.
For engineers reviewing the S3DH datasheet, S3DH pinout, S3DH application, or S3DH equivalent, key selection criteria include repetitive peak reverse voltage (200 V), junction-to-lead thermal resistance (13 °C/W), reverse recovery time (1500 ns), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
The S3DH is a single-die, glass-passivated standard recovery rectifier optimized for DC-DC conversion and snubber circuits where moderate switching speed and high surge robustness are prioritized over ultrafast recovery. Its 1500 ns reverse recovery time and 60 pF junction capacitance reflect trade-offs favoring ruggedness over high-frequency operation.
Designed for surface-mount automated placement, it supports reflow soldering per J-STD-002 with matte tin-plated leads, operates across –55°C to +150°C junction temperature range, and meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum non-repetitive reverse blocking voltage; defines safe operating limit in DC-DC flyback or snubber clamp circuits |
| IF | 3 A continuous - Rated average forward current at case temperature ≤ 75°C; determines heatsinking needs in power supply designs |
| IFSM (8.3 ms) | 100 A - Peak non-repetitive surge current handling; critical for inrush and transient protection in automotive lighting |
| VF (3 A, 25°C) | ≤1.15 V - Forward voltage drop directly impacts conduction loss and thermal rise in high-current rectification paths |
| trr | 1500 ns - Reverse recovery time affects switching losses and EMI in medium-frequency (<100 kHz) converters |
| RθJL | 13 °C/W - Junction-to-lead thermal resistance enables direct PCB copper pour thermal management without dedicated heatsink |
| Junction temp. range | –55°C to +150°C - Enables deployment in under-hood automotive environments and industrial power supplies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L02S (STMicroelectronics) | Same 3 A / 200 V rating; faster trr (75 ns); higher VF (1.3 V typ) | Better suited for higher-frequency SMPS (>100 kHz); less ideal for high-surge automotive lighting | Select when switching frequency >50 kHz dominates design priority over surge margin |
| VS-3EYH02-M3 (Vishay) | Same DO-214AB package; 200 V VRRM; lower IFSM (75 A); halogen-free but not AEC-Q101 qualified | Acceptable for industrial/commercial DC-DC; not certified for automotive production | Choose for cost-sensitive non-automotive applications where AEC-Q101 is not mandated |
Compared with STTH3L02S and VS-3EYH02-M3, the S3DH delivers superior surge robustness (100 A vs. 75–80 A) and automotive qualification at the expense of slower recovery-making it optimal for ruggedized 20–50 kHz power stages where reliability outweighs speed.

FAQ
What is the maximum junction temperature rating for the S3DH?
The S3DH has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet Version B2301. This allows the S3DH to operate reliably in under-hood automotive environments and high-ambient industrial settings. Derating curves confirm usable current capacity down to ambient temperatures up to 125°C when properly mounted on adequate copper area. The S3DH must not exceed this limit during steady-state or transient conditions.
Is the S3DH pin-compatible with other devices in the S3xH series?
Yes-the S3DH shares identical DO-214AB (SMC) package dimensions, pinout, and thermal pad layout with all members of the S3xH family (S3AH through S3MH). The only differences are VRRM ratings (50 V to 1000 V) and corresponding marking codes (S3D for S3DH). This uniformity allows board-level voltage scalability without layout changes. The S3DH itself uses the "S3D" marking code on its cathode band.
Does the S3DH meet automotive qualification standards?
Yes-the S3DH is explicitly AEC-Q101 qualified per the Taiwan Semiconductor datasheet Version B2301. This includes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD). Its glass-passivated junction, moisture sensitivity level 1, and halogen-free construction further support automotive production use. The S3DH is approved for automotive lighting, body control modules, and DC-DC converters where AEC-Q101 compliance is mandatory.
What is the reverse recovery time (trr) specification for the S3DH?
The S3DH has a typical reverse recovery time (trr) of 1500 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the electrical specifications table. This value reflects its standard recovery rectifier architecture-optimized for robustness rather than ultrafast switching. Designers should account for this trr when calculating switching losses and snubber sizing in topologies operating below 100 kHz. The S3DH datasheet confirms no faster variants exist within the same package.
Can the S3DH be used in a surface-mount reflow process without baking?
Yes-the S3DH has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH and subjected to standard Pb-free reflow profiles (e.g., JEDEC J-STD-020) without prior baking. Its matte tin-plated leads comply with J-STD-002 for solderability, and the DO-214AB package is rated for peak reflow temperatures up to 260°C. No floor life restrictions apply, simplifying SMT line logistics for the S3DH.
