Product details
Overview
S3JBH from Taiwan Semiconductor is a surface-mount silicon rectifier diode with 600 V repetitive peak reverse voltage (VRRM), 3 A average forward current (IF), and 80 A surge capability (IFSM), designed for freewheeling, snubber, and automotive DC-DC converter circuits.
For engineers reviewing the S3JBH datasheet, S3JBH pinout, S3JBH application, or S3JBH equivalent, key selection criteria include its DO-214AA (SMB) package, 1.15 V max forward voltage at 3 A, 250 µA max reverse leakage at 125°C, 1500 ns reverse recovery time, and AEC-Q101 qualification for automotive use.
Technical Context
The S3JBH is a single-die, standard recovery rectifier optimized for moderate-speed switching in power conversion stages where low conduction loss and high surge robustness are prioritized over ultra-fast recovery. Its 1500 ns trr and 40 pF junction capacitance reflect trade-offs favoring thermal stability and ruggedness over high-frequency operation.
It operates across –55°C to +150°C junction temperature range, features glass-passivated junction for reliability, and meets J-STD-020 moisture sensitivity level 1-enabling standard reflow without baking. The cathode band clearly indicates polarity on the DO-214AA molded case.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S (STMicroelectronics) | Same DO-214AA package, 600 V VRRM, but faster trr = 75 ns; VF = 1.3 V @ 3 A | Better suited for high-frequency SMPS (>200 kHz); higher VF increases conduction loss | Select when switching speed outweighs conduction efficiency in compact designs |
| ES3J (ON Semiconductor) | Same 600 V/3 A rating, DO-214AA, trr = 1500 ns, VF = 1.15 V - near-identical electrical specs | Not AEC-Q101 qualified; rated for commercial/industrial, not automotive | Use in cost-sensitive industrial supplies where automotive qualification is unnecessary |
Compared with STTH3L06S and ES3J, the S3JBH uniquely combines AEC-Q101 qualification, 1.15 V VF, and 1500 ns trr in a single SMB package-making it optimal for automotive-grade 50–100 kHz converters requiring ruggedness and thermal margin.

FAQ
What is the maximum junction temperature rating for the S3JBH?
The S3JBH has a maximum junction temperature (TJ) rating of +150°C, with a storage temperature range of –55°C to +150°C. This rating enables reliable operation in under-hood automotive environments and enclosed industrial power supplies. Thermal design must account for RθJL = 10°C/W and ensure adequate PCB copper area to maintain TJ ≤ 150°C under full 3 A load.
Is the S3JBH suitable for automotive applications?
Yes, the S3JBH is AEC-Q101 qualified and explicitly listed for automotive applications including car lighting and DC-DC converters. Its glass-passivated junction, moisture sensitivity level 1, and –55°C to +150°C operating range meet stringent automotive reliability requirements. The S3JBH marking code "S3JB" and DO-214AA package comply with automotive manufacturing standards.
What does the "J" in S3JBH indicate?
The "J" in S3JBH denotes the 600 V repetitive peak reverse voltage (VRRM) rating within the S3x series family. Per the ordering table, S3ABH = 50 V, S3BBH = 100 V, S3DBH = 200 V, S3GBH = 400 V, S3JBH = 600 V, S3KBH = 800 V, and S3MBH = 1000 V. The "H" suffix indicates tape-and-reel packaging (3,000 units).
How does the S3JBH compare to fast recovery diodes in snubber circuits?
The S3JBH offers 1500 ns reverse recovery time (trr), classifying it as a standard recovery rectifier-not a fast or ultrafast type. In snubber applications, this slower trr provides gentler voltage transitions and reduced EMI compared to sub-100 ns diodes, while its 1.15 V VF and 600 V rating deliver effective clamping with minimal conduction loss. It is preferred where EMI control and ruggedness outweigh switching speed needs.
What is the recommended PCB pad layout for the S3JBH?
Taiwan Semiconductor specifies a suggested pad layout for the DO-214AA (SMB) package in the datasheet (Page 5). It recommends symmetrical, thermally enhanced pads with ≥10 mm² total copper area per lead to leverage the 10°C/W RθJL. The cathode band must align with silkscreen polarity marking, and solder mask defined (SMD) pads are advised to prevent bridging during reflow.
