Product details

Overview

S15JC from Taiwan Semiconductor is a 15A, 600V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, low forward voltage drop (≤1.1 V at 15 A), and high surge capability (350 A, 8.3 ms). It serves as a freewheeling or output rectifier in switching-mode power supplies for telecom and computing systems.

For engineers reviewing the S15JC datasheet, S15JC pinout, S15JC application, or S15JC equivalent, key selection criteria include its 600 V repetitive peak reverse voltage, 15 A average forward current rating, thermal resistance (R_θJL = 8 °C/W), and RoHS/halogen-free compliance for industrial-grade power conversion designs.

Technical Context

The S15JC is a single-die, standard recovery silicon rectifier optimized for high-current DC output stages and inductive energy recirculation. Its glass-passivated junction ensures stable reverse leakage (<1 µA at 25°C, <250 µA at 125°C) and robust surge tolerance under repetitive switching stress.

Thermally, it leverages the DO-214AB (SMC) package's low junction-to-lead resistance (8 °C/W) to sustain 15 A continuous conduction at up to 150°C junction temperature, with derating beginning above 75°C ambient per published curves.

Equivalent & Alternatives

The following parts are listed as comparable options for similar rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1506D (STMicroelectronics)	Same 600 V V_RRM, 15 A I_F, but faster recovery (t_rr = 65 ns vs. S15JC's standard recovery); higher V_F (1.25 V)	Better suited for high-frequency PFC stages; less optimal for low-loss DC output where V_F dominates	Select STTH1506D only if fast recovery is required and V_F penalty is acceptable
VS-15EWH06FN-M3 (Vishay)	Identical DO-214AB package, same 600 V/15 A ratings, but enhanced moisture resistance (MSL level 1 confirmed), slightly higher R_θJA (48 °C/W)	Preferred for humid-environment deployments (e.g., outdoor telecom cabinets); identical layout compatibility	Choose VS-15EWH06FN-M3 when extended MSL reliability or Vishay supply chain alignment is prioritized

Compared with STTH1506D and VS-15EWH06FN-M3, the S15JC offers the lowest forward voltage in its class-critical for thermally constrained 15 A rectification-while maintaining full DO-214AB mechanical compatibility and J-STD-020 Level 1 moisture robustness without requiring layout changes.

FAQ

What is the maximum junction temperature rating for the S15JC?

The S15JC has a maximum junction temperature (T_J) rating of +150°C, with a storage temperature range of −55°C to +150°C. This allows sustained operation in high-ambient environments such as enclosed telecom power modules, provided thermal design maintains junction temperature within limit using the specified R_θJL = 8 °C/W path. Derating curves in the S15JC datasheet define safe current limits above 75°C ambient.

Does the S15JC have a defined cathode marking, and how is polarity identified?

Yes, the S15JC uses a visible cathode band on the DO-214AB (SMC) package body to indicate polarity. The banded end corresponds to the cathode terminal (Lead 2), while the unmarked end is the anode (Lead 1). This marking complies with industry-standard orientation for surface-mount rectifiers and is verified in TSC's marking diagram for the S15JC.

What is the reverse leakage current specification for the S15JC at elevated temperature?

The S15JC specifies reverse leakage current (I_R) ≤1 µA at 25°C and ≤250 µA at 125°C, measured at rated V_RRM. These values are confirmed under pulse test conditions (PW = 30 ms) and reflect stable glass-passivated junction behavior across its operational temperature range, supporting reliable blocking in high-temperature power conversion stages.

Is the S15JC suitable for use in RoHS-compliant and halogen-free assemblies?

Yes, the S15JC is fully RoHS compliant and halogen-free per IEC 61249-2-21. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its molding compound carries UL 94V-0 flammability rating-making it qualified for environmentally regulated industrial and computing end equipment without process or compliance requalification.

What is the surge current rating of the S15JC, and under what waveform is it specified?

The S15JC is rated for a peak forward surge current (I_FSM) of 350 A, specified for a single 8.3 ms half-sine wave superimposed on rated DC load. This rating is validated per JEDEC standards and enables robust handling of inrush currents and fault transients in switching power supplies without requiring external fusing or derating in typical 50/60 Hz line-frequency or 100–500 kHz SMPS applications.
