Product details
Overview
S15JCH from Taiwan Semiconductor is a surface-mount silicon rectifier diode rated for 15 A average forward current and 600 V repetitive peak reverse voltage, featuring glass passivated junction, low forward voltage drop (≤1.1 V at 15 A), and AEC-Q101 qualification for automotive use in DC-DC converters and car lighting systems.
For engineers reviewing the S15JCH datasheet, S15JCH pinout, S15JCH application, or S15JCH equivalent, key selection criteria include its DO-214AB (SMC) package, 350 A non-repetitive surge capability, 8 °C/W junction-to-lead thermal resistance, and moisture sensitivity level 1 compliance - all critical for high-reliability automotive power rectification.
Technical Context
The S15JCH is a single-die, unidirectional silicon rectifier optimized for high-current, medium-voltage AC/DC and DC/DC conversion. Its glass-passivated junction ensures stable reverse leakage (<1 µA at 25°C, <250 µA at 125°C) and robust surge tolerance under 8.3 ms half-sine transients.
Thermally, it delivers 8 °C/W junction-to-lead resistance and 44 °C/W junction-to-ambient resistance in the DO-214AB (SMC) package, enabling efficient heat transfer to PCB copper when mounted with recommended pad layout. Polarity is marked by a cathode band on the molded case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage the device blocks reliably in circuit |
| IF(AV) | 15 A - continuous average forward current rating at TC = 75°C per JEDEC standards |
| IFSM | 350 A - peak non-repetitive surge current handling for 8.3 ms half-sine, critical for inrush protection |
| VF | ≤1.1 V @ 15 A, 25°C - low conduction loss enabling higher efficiency in high-current rectification stages |
| IR | ≤1 µA @ 600 V, 25°C - minimal reverse leakage preserves system standby power and snubber integrity |
| RθJL | 8 °C/W - enables direct thermal coupling to PCB copper for effective junction temperature control |
| TJ max | +150°C - supports operation in under-hood automotive environments without derating penalties |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1506D (STMicroelectronics) | 600 V VRRM, 15 A IF, TO-220AC package, VF = 1.15 V @ 15 A, RθJA = 30 °C/W | Through-hole mounting; higher thermal resistance requires heatsink even at 10 A | Prefer for prototyping or low-volume through-hole designs where board space permits heatsinking |
| VS-15EWH06FN-M3 (Vishay) | 600 V VRRM, 15 A IF, DO-214AB package, VF = 1.05 V @ 15 A, RθJL = 7.5 °C/W, AEC-Q101 qualified | Near-identical footprint and qualification; slightly lower VF and better thermal resistance | Drop-in alternative if tighter VF budget or margin-critical thermal design is required |
Compared with STTH1506D, the S15JCH offers surface-mount compatibility and superior thermal performance in constrained spaces; versus VS-15EWH06FN-M3, it trades marginal VF reduction for broader supply chain availability and identical qualification status - both alternatives require validation of marking and solder profile compatibility.

FAQ
What is the maximum junction temperature rating for the S15JCH?
The S15JCH has a maximum junction temperature (TJ max) of +150°C, verified per JEDEC JESD22-A108 and supported by its 8 °C/W junction-to-lead thermal resistance. This rating allows uninterrupted operation in under-hood automotive environments when mounted on ≥1 sq.in. of 2 oz. copper with thermal vias. The S15JCH must not exceed this limit during steady-state or transient conditions to maintain reliability and AEC-Q101 compliance.
Is the S15JCH pin-compatible with other devices in the S15xCH series?
Yes, all S15xCH variants - including S15GCH, S15JCH, S15KCH, and S15MCH - share identical DO-214AB (SMC) package dimensions, pinout, and thermal pad layout. The only difference is VRRM rating (400 V to 1000 V), so S15JCH can be substituted within the same footprint when 600 V blocking is sufficient. The S15JCH marking code "S15JC" is laser-etched on the cathode-banded side.
Does the S15JCH require special handling during reflow soldering?
No - the S15JCH is rated moisture sensitivity level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and placed directly into standard lead-free reflow profiles (peak 260°C) without baking. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the UL 94V-0 epoxy withstands thermal cycling without delamination. No special handling is needed beyond standard SMT practices for the S15JCH.
What is the reverse leakage current specification for the S15JCH at elevated temperature?
At TJ = 125°C and VR = 600 V, the S15JCH exhibits a maximum reverse leakage current (IR) of 250 µA, measured using a 30 ms pulse per datasheet Note 2. This value is critical for snubber and standby-loss-sensitive applications. At 25°C, IR is ≤1 µA - confirming stable junction integrity. These values are guaranteed across production lots and validated during AEC-Q101 stress testing for the S15JCH.
Can the S15JCH be used in place of a Schottky diode in high-frequency applications?
No - the S15JCH is a standard PN-junction silicon rectifier with typical reverse recovery time (trr) not specified in the datasheet, indicating it is not optimized for high-frequency switching (>100 kHz). Its 93 pF junction capacitance and lack of fast-recovery characterization make it unsuitable as a Schottky replacement in synchronous rectifiers or resonant converters. Use only in line-frequency or low-kHz applications such as AC-DC front ends or snubbers where the S15JCH's surge and thermal advantages outweigh speed limitations.
