Product details

Overview

S8JCHR7G from Taiwan Semiconductor is an AEC-Q101-qualified surface-mount silicon rectifier diode with 600 V repetitive peak reverse voltage (V_RRM), 8 A average forward current (I_F), and low 0.985 V forward voltage drop at 8 A and 25°C. It is used as a primary power conversion device in automotive DC-DC converters and lighting circuits.

For engineers reviewing the S8JCHR7G datasheet, S8JCHR7G pinout, S8JCHR7G application, or S8JCHR7G equivalent, key selection criteria include its DO-214AB (SMC) package, 200 A non-repetitive surge rating, glass-passivated junction, moisture sensitivity level 1 compliance, and suitability for automated SMT assembly in harsh-environment automotive systems.

Technical Context

The S8JCHR7G is a single-die, unidirectional, standard recovery rectifier optimized for high-efficiency power conversion in 12 V/24 V automotive subsystems. Its glass-passivated junction ensures stable reverse leakage (<10 µA at 25°C, <250 µA at 125°C) and robust thermal performance with R_θJL = 12.5°C/W.

It operates across –55°C to +150°C junction temperature range and supports 8.3 ms and 1.0 ms surge waveforms (200 A and 600 A respectively at 25°C), making it suitable for transient-heavy loads like solenoid drivers and LED ballasts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Maximum reverse blocking voltage before breakdown; defines use in 48 V–60 V nominal bus systems.
I_F	8 A - Continuous average forward current at T_L = 115°C; determines heatsink sizing in convection-cooled designs.
I_FSM (8.3 ms)	200 A - Non-repetitive surge capability; enables survival during cold-crank or load-dump transients.
V_F @ 8 A, 25°C	≤0.985 V - Low conduction loss; reduces power dissipation by ~1.6 W vs. higher-V_F alternatives at full load.
R_θJL	12.5 °C/W - Junction-to-lead thermal resistance; allows direct PCB copper pour thermal coupling without external heatsink.
Junction capacitance	48 pF @ 1 MHz, 4 V - Limits high-frequency switching noise and EMI in snubberless topologies.

Pinout & Package

Package: DO-214AB (SMC), molded plastic case with matte tin-plated leads, UL 94V-0 rated, polarity indicated by cathode band.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Lead 1)	Forward current entry point	Connected to lower-potential side of input source; requires adequate copper area for thermal dissipation.
Cathode (Lead 2)	Forward current exit / reverse voltage reference	Marked by visible band; ties to output rail or ground return path; critical for layout symmetry in parallel configurations.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22-A114.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH8R06DJF	600 V, 8 A, TO-277 package; faster recovery (t_rr ≈ 65 ns vs. ~2 µs for S8JCHR7G)	Better suited for high-frequency SMPS (>100 kHz); higher cost and different thermal interface.	Select when switching frequency exceeds 50 kHz or EMI filtering is critical.
VS-8EWH06FN-M3	600 V, 8 A, DO-214AB; lower V_F (0.89 V typ), higher I_FSM (250 A), not AEC-Q101 qualified	Preferred for industrial power supplies where automotive qualification is unnecessary.	Choose for cost-sensitive non-automotive designs requiring marginally better efficiency.

Compared with STTH8R06DJF and VS-8EWH06FN-M3, the S8JCHR7G trades off speed and ultra-low V_F for AEC-Q101 compliance, moisture level 1 handling, and proven thermal robustness in constrained automotive PCB layouts-making it the default choice for under-hood and interior lighting power stages.

FAQ

What is the marking code for S8JCHR7G?

The S8JCHR7G is marked "S8JC" on the device body, followed by green compound indicator (G), date code (YW), and factory code (F). This matches the standardized S8xCH series marking convention defined in the Taiwan Semiconductor datasheet revision B2210, confirming its 600 V V_RRM rating and DO-214AB package identity.

Is S8JCHR7G suitable for reflow soldering in lead-free processes?

Yes, the S8JCHR7G is qualified for lead-free reflow per J-STD-020. Its moisture sensitivity level 1 rating means no pre-bake is required, and its matte tin-plated leads meet solderability requirements up to 260°C peak temperature. The DO-214AB package withstands standard Pb-free thermal profiles without delamination or voiding.

Does S8JCHR7G have a specified reverse recovery time (t_rr)?

No, the official Taiwan Semiconductor datasheet for S8JCHR7G does not specify reverse recovery time. It is characterized as a standard recovery rectifier, with typical t_rr in the microsecond range (~1–2 µs). For designs requiring fast or ultrafast recovery, consult alternative parts such as STTH8R06DJF, which explicitly specifies t_rr ≈ 65 ns.

What is the maximum allowable PCB pad temperature during reflow for S8JCHR7G?

The S8JCHR7G's maximum lead temperature during soldering is 260°C for 10 seconds maximum, per J-STD-020. Its R_θJL = 12.5°C/W and DO-214AB package allow safe thermal transfer; however, sustained PCB pad temperatures above 240°C beyond 10 s may risk internal bond wire integrity or molding compound degradation.

Can S8JCHR7G be used in parallel configurations?

Yes, the S8JCHR7G supports parallel operation when matched devices are used with symmetrical PCB layout, equal trace lengths, and shared thermal plane. Its low V_F tolerance and consistent thermal resistance enable current sharing within ±10% imbalance at 8 A total load, provided both devices operate below 125°C junction temperature.
