Product details
Overview
S3KBHR5G from Taiwan Semiconductor is a 3A, 800V standard surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring glass-passivated junction, 1.15V max forward voltage at 3A/25°C, 80A surge capability, and 150°C max junction temperature - used in AC/DC front-end rectification for industrial SMPS and LED drivers.
For engineers reviewing the S3KBHR5G datasheet, S3KBHR5G pinout, S3KBHR5G application, or S3KBHR5G equivalent, key selection criteria include repetitive peak reverse voltage (800V), forward current rating (3A), thermal resistance (10°C/W), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
This standard recovery rectifier uses a single-die silicon PN junction with glass passivation for stable reverse blocking and robust surge handling. Its 1500ns reverse recovery time (trr) and 40pF junction capacitance at 4V bias indicate suitability for non-critical switching applications below ~100kHz.
The device operates across –55°C to +150°C junction range, with thermal resistance from junction-to-lead rated at 10°C/W. Cathode polarity is marked by a visible band on the SMB molded case, and terminals are matte tin-plated per J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Maximum repetitive reverse voltage the diode blocks without breakdown; defines minimum input voltage derating margin in bridge or single-phase rectifiers. |
| IF | 3 A - Continuous average forward current at TA = 75°C; determines heatsink sizing and PCB copper area requirements. |
| IFSM | 80 A - Non-repetitive peak surge current (8.3ms half-sine); supports inrush tolerance during power-up in offline converters. |
| VF | ≤1.15 V @ 3A, 25°C - Forward voltage drop directly impacts conduction loss and thermal rise in high-current rectification stages. |
| trr | 1500 ns - Reverse recovery time affects switching loss and EMI in hard-switched topologies; not suitable for high-frequency synchronous rectification. |
| RθJL | 10 °C/W - Junction-to-lead thermal resistance enables direct thermal path to PCB copper; critical for estimating junction temperature under load. |
| IR | ≤10 µA @ 800V, 25°C - Low leakage ensures minimal standby power loss in high-voltage hold-up circuits. |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, molded epoxy case with matte tin-plated leads, UL 94V-0 rated, cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC input or transformer secondary; must withstand full surge current and reverse voltage stress. |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to output capacitor positive rail; carries full DC output current and defines reverse voltage reference. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enhances long-term reliability and humidity resistance in unsealed industrial environments without conformal coating. |
| J-STD-020 Level 1 moisture sensitivity | Enables direct placement without baking; eliminates pre-reflow dry storage requirements for manufacturing. |
| RoHS and halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS directives; supports green product certification and export compliance. |
| Single-die configuration | Ensures predictable thermal behavior and avoids mismatch-related failure modes seen in multi-die parallel configurations. |
Applications
| Industrial SMPS Input Rectification | LED Driver Bulk Rectification |
|---|---|
Use Scenario: Full-wave bridge rectification of 230VAC mains in open-frame 50–100W industrial switch-mode power supplies. IC Role / Device Role / Timing Role: Primary AC-to-DC conversion element; handles continuous 3A output current and 800V PIV stress. Use Value: Low VF minimizes conduction loss at 3A; 80A IFSM accommodates cold-start surges without degradation. | Use Scenario: Single-phase rectification feeding constant-current LED driver ICs in outdoor street lighting fixtures. IC Role / Device Role / Timing Role: High-voltage input stage rectifier; operates continuously at elevated ambient temperatures up to 85°C. Use Value: 150°C TJ rating and 10°C/W RθJL allow reliable operation without active cooling in sealed enclosures. |
| AC/DC Adapter Output Stage | DC-DC Converter Input Protection |
Use Scenario: Secondary-side rectification in universal-input (90–264VAC) wall adapters delivering ≤36V/2A. IC Role / Device Role / Timing Role: Standard recovery diode in flyback or forward converter output; paired with low-ESR bulk capacitor. Use Value: 1.15V VF balances efficiency and cost vs. Schottky alternatives; SMB footprint simplifies automated assembly. | Use Scenario: Input polarity protection and transient clamping in isolated 24V/48V DC-DC modules powered from industrial bus rails. IC Role / Device Role / Timing Role: Reverse-biased blocking diode preventing backfeed; conducts only during fault or hot-swap events. Use Value: 800V VRRM provides 2× safety margin over 400V bus transients; 10µA IR limits quiescent drain in always-on systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600V VRRM, 3A IF, TO-277 package, trr = 75ns | Higher-speed recovery enables use in higher-frequency PFC stages; requires different footprint and thermal pad layout. | Select when faster recovery and lower EMI are required, and board layout allows TO-277 mounting. |
| ON Semi MUR3060CT | 600V VRRM, dual common-cathode die, D²PAK package, trr = 60ns | Dual configuration supports center-tapped or synchronous designs; larger package demands more PCB area and thermal mass. | Choose for dual-output or interleaved rectification where space permits D²PAK and performance justifies cost premium. |
Compared with STTH3L06S and MUR3060CT, the S3KBHR5G offers higher voltage rating (800V vs. 600V), lower cost, and SMB compatibility for legacy layouts - but trades off speed (1500ns vs. <80ns) and thermal performance (10°C/W vs. ~2.5°C/W).

FAQ
What is the maximum junction temperature rating for the S3KBHR5G?
The S3KBHR5G has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating enables reliable operation in enclosed industrial environments where ambient temperatures exceed 85°C. Derating curves confirm usable current capacity down to zero amps at 150°C case temperature. The S3KBHR5G must be mounted on adequate copper area to maintain this limit under full load.
Is the S3KBHR5G RoHS and halogen-free compliant?
Yes, the S3KBHR5G is fully RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the "Features" section of the Taiwan Semiconductor datasheet. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin-plated to J-STD-002 standards. These certifications are documented in the official M2102 revision datasheet for the S3AB–S3MB family, which includes the S3KBHR5G.
What does the 'HR5G' suffix in S3KBHR5G indicate?
The 'HR5G' suffix in S3KBHR5G denotes Taiwan Semiconductor's internal tape-and-reel packaging code: 'H' = DO-214AA (SMB) package, 'R5' = 3,000-piece reel quantity, and 'G' = green (halogen-free) compound. This matches the ordering information table in the S3AB–S3MB datasheet, where 'S3xB' is the base code and suffixes define packaging and environmental attributes - not electrical variants.
Can the S3KBHR5G replace a Schottky diode in a 24V output rectifier?
No, the S3KBHR5G is not a suitable replacement for a Schottky diode in low-voltage output rectification due to its higher forward voltage (≤1.15V vs. ≤0.5V for Schottkys) and slow recovery (1500ns). In a 24V output stage, this would increase conduction loss and cause excessive heating. The S3KBHR5G is optimized for high-voltage input rectification (e.g., 800V PIV), not low-VF secondary-side use. Use the S3KBHR5G only where its 800V rating and surge capability are required.
What is the reverse leakage current specification for the S3KBHR5G at 125°C?
At 125°C junction temperature and rated reverse voltage (800V), the S3KBHR5G exhibits a maximum reverse leakage current (IR) of 250 µA, as specified in the "ELECTRICAL SPECIFICATIONS" table of the Taiwan Semiconductor datasheet. This value is measured under pulse conditions (PW = 30ms) and reflects typical thermal drift behavior. At 25°C, IR is limited to 10 µA - critical for minimizing standby power loss in energy-sensitive designs using the S3KBHR5G.
