Product details

Overview

S3JHR7G from Taiwan Semiconductor is a surface-mount silicon rectifier diode with 600 V repetitive peak reverse voltage (V_RRM), 3 A average forward current (I_F), and 100 A non-repetitive surge capability (I_FSM); it features low 1.15 V forward voltage at 3 A, 1500 ns reverse recovery time, and DO-214AB (SMC) package - used in AC/DC front-end rectification for switching mode power supplies.

For engineers reviewing the S3JHR7G datasheet, S3JHR7G pinout, S3JHR7G application, or S3JHR7G equivalent, key selection criteria include V_RRM = 600 V, I_F = 3 A, thermal resistance R_θJA = 47 °C/W, moisture sensitivity level 1, and RoHS/halogen-free compliance for industrial SMPS and lighting converter designs.

Technical Context

This device is a single-die, glass-passivated, standard recovery rectifier optimized for cost-sensitive, medium-voltage AC/DC conversion where fast recovery is not required. Its 1500 ns trr and 60 pF junction capacitance reflect trade-offs favoring low conduction loss over switching speed.

Designed for automated placement and reflow soldering, the S3JHR7G meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements. Polarity is marked by a cathode band on the DO-214AB molded body.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports 400 VAC input rectification with 1.5× safety margin in universal-input SMPS
I_F	3 A continuous - suitable for output rectification in 75–100 W converters
I_FSM (8.3 ms)	100 A - withstands inrush surges during cold-start of offline power supplies
V_F @ 3 A	1.15 V max - limits conduction loss to ≤3.45 W at full load, reducing heatsink demand
T_J max	+150 °C - enables operation in high-ambient environments such as enclosed LED drivers
R_θJA	47 °C/W - requires ≥1.5 cm² copper pour for thermal management at full I_F

Pinout & Package

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L06S	V_RRM = 600 V, I_F = 3 A, but trr = 75 ns (ultrafast); VF = 1.3 V @ 3 A	Better suited for higher-frequency PFC stages where switching loss dominates	Select S3JHR7G when conduction loss and cost are prioritized over switching speed
ON Semi MUR360	V_RRM = 600 V, I_F = 3 A, trr = 50 ns, VF = 1.25 V @ 3 A; DO-214AC (SMA) package	Smaller footprint but lower surge rating (I_FSM = 75 A) and higher thermal resistance	Choose S3JHR7G for higher surge robustness and better thermal dissipation in space-constrained but thermally demanding layouts

Compared with STTH3L06S and MUR360, the S3JHR7G trades faster recovery for lower forward voltage and superior surge capability in a thermally efficient DO-214AB package - making it optimal for line-frequency rectification where efficiency and ruggedness outweigh switching speed.

FAQ

What is the maximum junction temperature rating for the S3JHR7G?

The S3JHR7G has a maximum junction temperature (T_J) of +150 °C, enabling operation in high-ambient environments such as enclosed LED drivers or industrial power modules. This rating is validated per absolute maximum ratings in the official Taiwan Semiconductor datasheet revision O2301. Derating curves confirm usable current down to −55 °C, supporting wide-temperature deployment of the S3JHR7G.

Does the S3JHR7G meet RoHS and halogen-free requirements?

Yes, the S3JHR7G is RoHS compliant and halogen-free per Taiwan Semiconductor's product documentation (Version O2301). The device uses lead-free matte tin plating on terminals and UL 94V-0 compliant molding compound, satisfying environmental compliance mandates for CE-marked lighting and power adapter designs using the S3JHR7G.

What is the reverse recovery time (trr) specification for the S3JHR7G?

The S3JHR7G has a reverse recovery time (t_rr) of 1500 ns under test conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value confirms its classification as a standard recovery rectifier - appropriate for 50/60 Hz line-frequency applications but not recommended for high-frequency (>100 kHz) topologies where ultrafast diodes like the STTH3L06S would be preferred instead of the S3JHR7G.

What package type does the S3JHR7G use, and what are its key mechanical attributes?

The S3JHR7G uses the DO-214AB (SMC) surface-mount package, with dimensions per JEDEC DO-214AB Issue D. Key attributes include 0.210 g weight, cathode band polarity marking, UL 94V-0 flammability rating, and JESD201 Class 2 whisker resistance - all confirmed in the official Taiwan Semiconductor mechanical data sheet for the S3JHR7G.

How does the S3JHR7G compare to the S3M variant in terms of voltage rating and application scope?

The S3JHR7G is rated for 600 V V_RRM, while the S3M variant is rated for 1000 V V_RRM. Both share identical I_F = 3 A, I_FSM = 100 A, and DO-214AB packaging. The S3JHR7G targets universal-input (90–264 VAC) SMPS and LED drivers, whereas the S3M suits higher-line applications such as 3-phase industrial rectifiers or 400 VDC bus systems - confirming distinct application boundaries within the same S3x family.
