Product details

Overview

S15JCHR7G from Taiwan Semiconductor is a 15A, 600V surface-mount glass-passivated silicon rectifier diode in DO-214AB (SMC) package, featuring low forward voltage drop (≤1.1 V at 15 A), high surge current capability (350 A), and junction temperature rating up to +150°C - used as freewheeling diode in switching-mode power supplies for telecom and computing infrastructure.

For engineers reviewing the S15JCHR7G datasheet, S15JCHR7G pinout, S15JCHR7G application, or S15JCHR7G equivalent, key selection criteria include repetitive peak reverse voltage (600 V), forward current rating (15 A), thermal resistance (R_θJL = 8 °C/W), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance per IEC 61249-2-21.

Technical Context

This single-die standard recovery rectifier operates with a maximum junction temperature of +150°C and supports continuous forward current of 15 A at case temperature ≤75°C. Its 600 V V_RRM rating and 350 A I_FSM (8.3 ms half-sine) enable robust operation in high-frequency DC-DC converters and offline SMPS.

Thermal performance is defined by R_θJL = 8 °C/W and R_θJA = 44 °C/W, with cathode polarity indicated by a band on the DO-214AB molded body. The device uses matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Maximum repetitive reverse voltage before breakdown; defines safe operating range in bridge or freewheeling configurations
I_F	15 A - Continuous average forward current at T_C = 75°C; determines heatsink sizing and conduction loss budget
I_FSM	350 A - Non-repetitive surge current (8.3 ms); enables survival during startup inrush or output short-circuit events
V_F	≤1.1 V @ 15 A, 25°C - Forward voltage drop directly impacts conduction loss and thermal design in high-current paths
R_θJL	8 °C/W - Junction-to-lead thermal resistance; critical for estimating die temperature rise under PCB copper pad cooling
C_J	93 pF @ 1 MHz, 4 V - Junction capacitance affects high-frequency switching noise and snubber design in fast-switching topologies

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1506D	600 V V_RRM, 15 A I_F, but faster recovery (t_rr ≈ 65 ns vs. standard recovery >1 µs); higher V_F (1.25 V)	Better suited for high-frequency PFC stages; less optimal for low-loss freewheeling where recovery loss is secondary to conduction loss	Select S15JCHR7G when conduction efficiency and thermal margin dominate; STTH1506D when EMI or switching frequency exceeds 100 kHz
ON Semi MUR1560	600 V V_RRM, 15 A I_F, ultrafast recovery (t_rr ≈ 50 ns), V_F = 1.2 V, R_θJA = 50 °C/W (higher than S15JCHR7G's 44 °C/W)	Preferred in resonant LLC or active clamp flyback where reverse recovery must be minimized	Choose S15JCHR7G for cost-sensitive, thermally constrained freewheeling; MUR1560 only if t_rr-driven losses exceed conduction losses in final layout

Compared with STTH1506D and MUR1560, the S15JCHR7G prioritizes low forward voltage and superior thermal resistance over speed - making it optimal for high-current, moderate-frequency freewheeling where conduction loss dominates total dissipation and board space limits heatsinking.

FAQ

What is the maximum junction temperature rating for the S15JCHR7G?

The S15JCHR7G has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet. This allows operation in high-ambient environments such as enclosed telecom power modules or industrial drive cabinets. Derating curves confirm usable current capacity down to 0 A at 150°C case temperature. Thermal design must respect R_θJL = 8 °C/W to avoid exceeding this limit under full-load conditions.

Is the S15JCHR7G RoHS and halogen-free compliant?

Yes, the S15JCHR7G is fully RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the "Features" section of the Taiwan Semiconductor datasheet. The device uses lead-free matte tin plating and halogen-free molding compound, meeting both EU RoHS Directive 2011/65/EU and China RoHS II requirements. No exemptions apply, and compliance is verified through material declarations and third-party testing.

What does the 'J' in S15JCHR7G indicate?

The 'J' in S15JCHR7G denotes the 600 V repetitive peak reverse voltage (V_RRM) rating within the S15x family - per Taiwan Semiconductor's ordering code convention where G=400V, J=600V, K=800V, and M=1000V. The 'HR7G' suffix indicates tape-and-reel packaging (7-inch reel, 3,000 pcs), green compound, and standard reliability grade. This coding is consistent across all S15GC–S15MC datasheet pages.

Can the S15JCHR7G be used as a direct replacement for S15JC?

Yes, the S15JCHR7G is functionally identical to S15JC - both specify 600 V V_RRM, 15 A I_F, DO-214AB package, and identical electrical/thermal parameters. The 'HR7G' suffix reflects packaging (tape-and-reel, 3k/reel) and environmental compliance (green/halogen-free), not functional change. No PCB or schematic modifications are required when substituting S15JCHR7G for S15JC in existing designs.

What is the reverse leakage current specification for the S15JCHR7G at elevated temperature?

The S15JCHR7G exhibits ≤250 µA reverse leakage current (I_R) at rated V_R and junction temperature of +125°C, per the Electrical Specifications table. At +25°C, I_R is ≤1 µA. This low leakage supports stable operation in high-temperature battery backup circuits and offline PSUs where standby power loss must remain minimal. Measured under 30 ms pulse conditions per datasheet note 2.
