Product details
Overview
S1DH from Taiwan Semiconductor is a 1A, 200V surface-mount silicon rectifier diode in DO-214AC (SMA) package, featuring glass-passivated junction, AEC-Q101 qualification, 1.1V max forward voltage at 1A/25°C, and 1500ns reverse recovery time. It serves as a primary AC/DC rectification device in automotive lighting and DC-DC converters.
For engineers reviewing the S1DH datasheet, S1DH pinout, S1DH application, or S1DH equivalent, key selection criteria include repetitive peak reverse voltage (200V), surge current rating (30A), thermal resistance (27°C/W junction-to-lead), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The S1DH operates as a single-die standard recovery rectifier with unidirectional conduction. Its 200V VRRM, 30A IFSM (8.3ms half-sine), and 1500ns trr define its suitability for medium-voltage, moderate-speed switching in non-resonant power stages.
Thermal performance is characterized by RθJL = 27°C/W and RθJA = 75°C/W, enabling 1A continuous operation up to 125°C ambient when mounted on minimum recommended copper area. Junction temperature range spans −55°C to +175°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR120 | 200V VRRM, 50ns trr, 1.3V VF max - faster but higher conduction loss | Better for high-frequency SMPS (>100kHz); less suitable for snubber use due to low trr-induced ringing | Select when switching speed dominates efficiency trade-off; verify layout EMI mitigation |
| Vishay VS-1EH02-M3 | 200V VRRM, 1000ns trr, 1.05V VF max - lower VF, slightly faster than S1DH | Optimized for 50–60Hz line-frequency rectification with tighter VF tolerance | Prefer for linear power supplies or low-ripple DC bus where conduction loss is critical |
Compared with MUR120 and VS-1EH02-M3, the S1DH offers balanced recovery speed and conduction loss with AEC-Q101 validation-making it uniquely suited for automotive lighting and industrial DC-DC where reliability, thermal robustness, and transient tolerance outweigh ultra-fast switching needs.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the S1DH?
The S1DH has a maximum repetitive peak reverse voltage (VRRM) of 200 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2102). This rating defines the highest reverse voltage the S1DH can block repeatedly without breakdown under normal operating conditions and is critical for selecting appropriate derating margins in 12V or 24V automotive systems.
Is the S1DH suitable for automotive applications?
Yes, the S1DH is AEC-Q101 qualified per the manufacturer's documentation, confirming its suitability for automotive applications including LED headlamps and body control modules. The S1DH undergoes rigorous stress testing-including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing-to ensure reliability in under-hood environments where junction temperatures may reach 175°C.
What is the forward voltage drop (VF) of the S1DH at rated current?
The S1DH exhibits a maximum forward voltage drop (VF) of 1.1 V at 1 A forward current and 25°C junction temperature, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents the worst-case conduction loss used for thermal design-actual VF decreases at lower currents and increases with rising temperature.
What package type does the S1DH use, and what are its mounting characteristics?
The S1DH uses the DO-214AC (SMA) surface-mount package, with matte tin-plated leads compliant with J-STD-002 solderability requirements. Its polarity is marked by a cathode band, and it carries MSL Level 1 moisture sensitivity-enabling direct placement without pre-baking. The package weighs approximately 0.060 g and meets UL 94V-0 flammability standards.
How does the S1DH compare to the S1AH and S1JH in terms of voltage rating and thermal resistance?
The S1DH has a 200 V VRRM, positioned between the 50 V S1AH and 600 V S1JH. Its junction-to-lead thermal resistance (RθJL) is 27 °C/W-identical to S1AH, S1BH, S1GH, and S1JH-but differs from the 30 °C/W of S1KH and S1MH. This uniformity within the mid-voltage group simplifies thermal design across multiple variants of the S1xH family, including the S1DH.
