Product details
Overview
S1DLSH from Taiwan Semiconductor is a 200V, 1.2A standard surface-mount silicon rectifier diode in SOD-123HE package, featuring 50A peak surge current capability, 1.3V max forward voltage at 1.2A, and AEC-Q101 qualification for automotive-grade reliability-used in DC-DC converter output rectification.
For engineers reviewing the S1DLSH datasheet, S1DLSH pinout, S1DLSH application, or S1DLSH equivalent, key selection criteria include repetitive peak reverse voltage (200V), thermal resistance (RθJA = 86°C/W), junction temperature range (–55°C to +175°C), and moisture sensitivity level (MSL 1).
Technical Context
The S1DLSH is a single-die, planar passivated silicon PN junction rectifier optimized for high-efficiency, low-loss operation in compact power conversion stages. Its SOD-123HE package enables automated placement and supports high-density PCB layouts while maintaining robust thermal performance on 5mm × 5mm copper pads.
Designed for unidirectional conduction, it delivers stable reverse blocking up to 200V with ≤5µA leakage at 25°C and ≤150µA at 125°C, and sustains 50A non-repetitive surge current per JESD22-A112 (8.3ms half-sine). Polarity is marked by a cathode band.
Key Specifications

| VF @ IF=1.2A | ≤1.3 V - forward voltage drop determining conduction loss in power stage |
| RθJA | 86 °C/W - junction-to-ambient thermal resistance on standard 5mm × 5mm Cu pad |
| TJ Range | –55°C to +175°C - operational junction temperature window enabling under-hood automotive use |
| MSL | Level 1 - no floor life limitation; safe for reflow without dry-pack requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 600V VRRM, 1A IF, TO-277 package, higher VF (1.7V typ) | Higher voltage rating but lower current and larger footprint | Select when >200V blocking is required and space allows TO-277 mounting |
| ON Semi MUR120 | 200V VRRM, 1A IF, DO-41 through-hole, faster recovery (~75ns) | Through-hole assembly only; not suitable for automated SMT lines | Choose only for legacy through-hole designs where rework or manual assembly is acceptable |

FAQ
What is the maximum junction temperature rating for the S1DLSH?
The S1DLSH has a maximum junction temperature (TJMAX) of +175°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version A2103). This rating enables reliable operation in under-hood automotive environments and high-temperature industrial enclosures. Derating curves in the datasheet define allowable current versus case temperature, and the S1DLSH must be mounted on a 5mm × 5mm copper pad to achieve its specified RθJA = 86°C/W.
Is the S1DLSH pin-compatible with other S1xLSH series variants like S1GLSH or S1JLSH?
No-the S1DLSH shares the same SOD-123HE package and two-terminal configuration with other S1xLSH variants, but voltage ratings differ (S1DLSH = 200V, S1GLSH = 400V, etc.), and marking codes vary (1DLS vs. 1GLS). While mechanical footprint is identical, electrical substitution requires verification of VRRM, IF, and thermal design margins. The S1DLSH itself is not a drop-in replacement for higher-voltage variants without circuit review.
Does the S1DLSH meet automotive qualification standards?
Yes-the S1DLSH is explicitly AEC-Q101 qualified per the Taiwan Semiconductor datasheet (Version A2103), covering stress tests for temperature cycling, humidity, mechanical shock, and high-temperature operating life. This certification confirms suitability for automotive powertrain, chassis, and body electronics applications, provided board-level thermal and layout design complies with datasheet recommendations.
What is the forward voltage specification for the S1DLSH at rated current?
The S1DLSH has a maximum forward voltage (VF) of 1.3 V at IF = 1.2 A and TJ = 25°C, measured under pulse conditions (PW = 0.3 ms). This value defines conduction loss in power stages; actual VF decreases slightly at lower currents and increases with junction temperature. The typical VF is not specified-only the maximum limit is guaranteed per datasheet Table "ELECTRICAL SPECIFICATIONS".
What packaging and reel quantity is offered for the S1DLSH?
The S1DLSH is supplied in tape-and-reel packaging with 10,000 units per reel, compatible with standard SMT pick-and-place equipment. The SOD-123HE package uses matte tin-plated leads solderable per J-STD-002, and the device carries a cathode band for polarity identification. No alternate packaging (e.g., bulk or ammo pack) is specified in the official ordering information for S1DLSH.
