Product details
Overview
HS3JBH from Taiwan Semiconductor is a 3A, 600V repetitive peak reverse voltage (VRRM), surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 1.7V forward voltage at 3A and 75ns reverse recovery time, designed for automotive freewheeling and DC-DC converter snubber circuits.
For engineers reviewing the HS3JBH datasheet, HS3JBH pinout, HS3JBH application, or HS3JBH equivalent, key selection criteria include its AEC-Q101 qualification, 100A surge rating, 150°C max junction temperature, low-profile SMB package compatibility with automated placement, and verified performance under 100°C reverse bias conditions.
Technical Context
This single-die, glass-passivated junction rectifier operates as a unidirectional current switch with fast recovery characteristics optimized for high-frequency switching power supplies. Its 75ns trr and 50pF junction capacitance support efficient operation in 100–500kHz DC-DC topologies while maintaining low conduction loss.
The device's thermal resistance of 60°C/W (junction-to-ambient) and moisture sensitivity level 1 rating enable reliable reflow soldering and long-term stability in under-hood automotive environments where ambient temperatures reach 125°C and humidity cycles are severe.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum non-repetitive reverse blocking voltage; defines safe operating range in snubber and flyback clamp circuits |
| IF | 3 A - Continuous average forward current; supports sustained power delivery in 12V/24V automotive DC-DC stages |
| VF @ 3A | 1.7 V - Forward voltage drop at rated current; determines conduction loss (5.1W max at 3A) and thermal load |
| trr | 75 ns - Reverse recovery time; enables stable operation up to ~500kHz switching without excessive switching loss |
| CJ @ 4V | 50 pF - Junction capacitance; limits high-frequency displacement current and EMI generation in fast-switching nodes |
| IFSM | 100 A - Non-repetitive surge current rating; withstands inrush and fault transients in automotive load-dump scenarios |
| TJ max | 150 °C - Maximum junction temperature; allows operation in engine compartment environments with derated current above 75°C |
Pinout & Package
DO-214AA (SMB) package: molded plastic case meeting UL 94V-0, matte tin-plated leads, cathode indicated by band, polarity-critical for correct circuit orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., ground side of inductive load); must handle full 3A continuous and 100A surge |
| Cathode | Forward current exit / reverse blocking terminal | Connected to higher-potential node (e.g., switch node); blocks 600V reverse voltage and carries recovered charge during trr |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD47 |
| Glass passivated chip junction | Prevents moisture-induced degradation and leakage current drift over 15-year vehicle lifetime |
| Moisture sensitivity level 1 | Enables standard SMT reflow without baking; eliminates production delays and handling overhead |
| Low profile SMB package | 1.7mm height enables compact PCB layouts in space-constrained modules like LED drivers and body control units |
| Halogen-free & RoHS compliant | Meets EU ELV and China RoHS requirements for end-of-life vehicle recycling and manufacturing safety |
Applications
| Automotive DC-DC Converters | LED Headlamp Drivers |
|---|---|
Use Scenario: Step-down conversion from 12V/48V battery to regulated 5V/3.3V for ADAS sensors and infotainment ECUs. IC Role / Device Role / Timing Role: Freewheeling diode in synchronous buck converter output stage, conducting during low-side FET off-time. Use Value: 75ns trr minimizes reverse recovery loss at 300kHz switching, while 600V VRRM provides margin against load dump transients. | Use Scenario: Constant-current regulation for high-brightness automotive headlamps using boost or buck-boost topology. IC Role / Device Role / Timing Role: Output rectifier in isolated flyback or non-isolated SEPIC converters driving 1–5A LED strings. Use Value: 1.7V VF reduces conduction loss vs. Schottky alternatives at >85°C ambient, improving thermal margin in sealed lamp housings. |
| Snubber Networks | Freewheeling in Solenoid Drivers |
Use Scenario: RCD snubber across MOSFETs in 48V starter-generator inverters to suppress voltage spikes during turn-off. IC Role / Device Role / Timing Role: Fast-recovery clamping diode that conducts transient energy into RC network within 75ns. Use Value: 50pF CJ limits capacitive coupling of high dv/dt noise into control circuitry, reducing EMI filter burden. | Use Scenario: Inductive load protection in transmission valve solenoids and HVAC actuators powered from 12V rail. IC Role / Device Role / Timing Role: Freewheeling path for stored inductor energy when driver FET turns off abruptly. Use Value: 100A IFSM safely absorbs 50ms inductive kickback pulses without degradation, ensuring 100,000+ cycle durability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600V VRRM, 3A IF, 1.85V VF @ 3A, 60ns trr, TO-277 package | Higher VF increases conduction loss; faster trr improves high-frequency efficiency but requires tighter layout | Preferred where board space permits larger TO-277 footprint and lower EMI is critical |
| SB360-E3/54 | 60V VRRM, 3A IF, 0.52V VF @ 3A, Schottky, DO-214AA | Insufficient reverse voltage rating for 12V automotive systems with load dump; limited to <40V applications | Only suitable for low-voltage DC-DC where reverse stress never exceeds 60V |
Compared with STTH3L06S and SB360-E3/54, the HS3JBH offers optimal balance of 600V robustness, 1.7V VF efficiency, and SMB footprint-making it the only AEC-Q101-qualified option among the three that meets both reverse voltage and thermal requirements for under-hood 12V/48V systems.

FAQ
What is the maximum junction temperature rating for HS3JBH?
The HS3JBH has a maximum junction temperature (TJ max) of +150°C, validated per AEC-Q101 stress testing. This allows continuous operation in engine bay environments up to 125°C ambient when derated per the forward current derating curve. The HS3JBH maintains stable reverse leakage (<250μA at 100°C) and forward voltage characteristics across this full range.
Is HS3JBH pin-compatible with other devices in the HS3x series?
Yes, all HS3ABH through HS3MBH share identical DO-214AA (SMB) package dimensions, anode/cathode pinout, and thermal pad layout. The HS3JBH uses the same physical footprint and soldering profile as HS3ABH, HS3BBH, and HS3MBH-enabling design reuse across 50V to 1000V variants without PCB revision.
Does HS3JBH meet automotive qualification standards?
Yes, HS3JBH is explicitly AEC-Q101 qualified per the manufacturer's datasheet Version A2102. It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress test (UHAST), confirming suitability for automotive powertrain and body electronics applications.
What is the reverse recovery time (trr) specification for HS3JBH?
The HS3JBH has a typical reverse recovery time (trr) of 75ns, measured at IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This value is confirmed in the Electrical Specifications table on page 2 of the official datasheet and enables efficient operation in 200–500kHz switching power supplies without excessive switching loss.
How does the forward voltage of HS3JBH compare to lower-voltage variants in the same family?
At 3A and 25°C, HS3JBH exhibits 1.7V forward voltage-higher than HS3ABH (1.0V) and HS3GBH (1.3V) due to increased doping and wider depletion region required for 600V blocking. This trade-off ensures robust reverse breakdown while maintaining competitive conduction loss for its voltage class; the HS3JBH remains the lowest-VF 600V rectifier in the HS3x family.
