Product details
Overview
S10KCH from Taiwan Semiconductor is a surface-mount silicon rectifier diode with 800 V repetitive peak reverse voltage (VRRM), 10 A average forward current (IF), and 250 A non-repetitive surge capability (IFSM). It features glass passivated junction, AEC-Q101 qualification, and DO-214AB (SMC) package-designed for automotive DC-DC converters and snubber circuits requiring high reliability under thermal stress.
For engineers reviewing the S10KCH datasheet, S10KCH pinout, S10KCH application, or S10KCH equivalent, key selection factors include its 800 V VRRM, 1.1 V max forward voltage at 10 A, 10 °C/W junction-to-lead thermal resistance, AEC-Q101 qualification, and DO-214AB mechanical compatibility in high-surge automotive power stages.
Technical Context
The S10KCH is a single-die, standard recovery rectifier optimized for medium-voltage, medium-current switching applications. Its glass-passivated junction ensures stable reverse leakage (<1 µA at 25°C, <250 µA at 125°C) and robust surge tolerance up to 250 A (8.3 ms half-sine).
Thermally, it delivers RθJL = 10 °C/W and RθJA = 47 °C/W in DO-214AB (SMC) package, enabling operation up to +150 °C junction temperature. Polarity is marked by cathode band; terminals are matte tin-plated per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Maximum reverse blocking voltage before breakdown; defines use in 800 V-class DC bus or snubber networks |
| IF | 10 A - Continuous average forward current at TA = 75°C; supports sustained conduction in automotive power supplies |
| IFSM | 250 A - Peak non-repetitive surge current (8.3 ms); withstands inrush and fault transients without failure |
| VF (max) | 1.1 V @ 10 A, 25°C - Low conduction loss improves efficiency in high-current rectification stages |
| RθJL | 10 °C/W - Enables direct thermal coupling to PCB copper; critical for thermal management in compact layouts |
| Junction Temp | –55°C to +150°C - Wide operating range supports under-hood automotive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-10EWH08-M3 | Same DO-214AB package, 800 V VRRM, but 1.25 V VF (max) and no AEC-Q101 certification | Not qualified for automotive under-hood use; suitable for industrial/commercial only | Select when AEC-Q101 is not required and higher VF is acceptable |
| ON Semiconductor MUR1080CT | TO-220AC package, dual common-cathode die, 800 V, 10 A per leg-but not surface-mount and lacks AEC-Q101 | Requires through-hole assembly and larger board area; unsuitable for automated SMT lines | Choose only if through-hole mounting and dual-diode topology are mandatory |
Compared with VS-10EWH08-M3 and MUR1080CT, the S10KCH uniquely combines AEC-Q101 qualification, DO-214AB SMT compatibility, and 1.1 V VF max-making it the only option for space-constrained, thermally demanding, automotive-qualified rectification where both reliability and efficiency are critical.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for the S10KCH?
The S10KCH has a VRRM rating of 800 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2102). This value is specific to the S10KCH variant and distinguishes it from S10GCH (400 V), S10JCH (600 V), and S10MCH (1000 V). The 800 V rating enables use in 48 V automotive systems with sufficient safety margin against voltage transients.
Is the S10KCH qualified for automotive applications?
Yes, the S10KCH is explicitly AEC-Q101 qualified per the manufacturer's documentation. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress test (UHAST), confirming suitability for under-hood automotive environments. The S10KCH datasheet states AEC-Q101 compliance as a core feature-not just the family-and applies directly to this exact part number.
What package type does the S10KCH use, and is it compatible with automated assembly?
The S10KCH uses the DO-214AB (SMC) surface-mount package, with matte tin-plated leads compliant with J-STD-002 solderability requirements. Its standardized footprint and MSL Level 1 rating make it fully compatible with high-speed pick-and-place equipment and reflow soldering processes-ideal for automotive module manufacturing where process consistency is critical.
What is the forward voltage (VF) specification for the S10KCH at rated current?
The S10KCH has a maximum forward voltage of 1.1 V at IF = 10 A and TJ = 25°C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss. At elevated junction temperatures, VF decreases slightly, supporting stable performance in thermally demanding applications like automotive DC-DC converters.
Does the S10KCH have any environmental compliance certifications?
Yes, the S10KCH is RoHS compliant and halogen-free per IEC 61249-2-21. These declarations are stated in the Features section of the official datasheet and verified through material declarations provided by Taiwan Semiconductor. The molding compound also meets UL 94V-0 flammability rating, supporting safety-critical automotive and industrial deployments.
