Product details
Overview
S3ABHR5G from Taiwan Semiconductor is a 3A, 50V 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 compact SMPS and LED drivers.
For engineers reviewing the S3ABHR5G datasheet, S3ABHR5G pinout, S3ABHR5G application, or S3ABHR5G equivalent, key selection criteria include repetitive peak reverse voltage (50V), thermal resistance (10°C/W), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and SMB footprint compatibility with automated placement.
Technical Context
This single-die standard recovery rectifier operates with a typical junction capacitance of 40pF at 1MHz/4V and exhibits a reverse recovery time of 1500ns under IF=0.5A, IR=1.0A, Irr=0.25A conditions - confirming its suitability for non-critical switching applications below 100kHz.
Its thermal design supports continuous 3A conduction with junction-to-lead resistance of 10°C/W, and it maintains ≤10µA reverse leakage at 25°C and ≤250µA at 125°C - enabling stable operation in ambient temperatures up to 125°C when properly heatsinked via PCB copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - maximum repetitive reverse voltage before breakdown; defines safe operating limit in bridge or single-phase rectifier configurations |
| IF | 3 A - average forward current rating; determines continuous power-handling capacity in DC output stages |
| IFSM | 80 A - non-repetitive surge current (8.3ms half-sine); supports inrush tolerance during cold-start in offline converters |
| VF (max) | 1.15 V @ 3A, 25°C - forward voltage drop directly impacts conduction loss and thermal rise in high-current paths |
| RθJL | 10 °C/W - junction-to-lead thermal resistance; enables estimation of junction temperature rise above lead temperature |
| trr | 1500 ns - reverse recovery time; limits usable frequency range and influences EMI generation in switching circuits |
| IR (max) | 10 µA @ 25°C - reverse leakage current; critical for low-power standby modes and high-impedance bias networks |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, cathode-indicated by band, matte tin-plated leads, UL 94V-0 molding compound, 0.090g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to AC input or transformer secondary; must withstand full surge current and thermal stress |
| Cathode | Current exit point during forward conduction | Marked by band; ties to output capacitor or smoothing choke; carries full load current to ground or return path |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enhances long-term reliability and humidity resistance without requiring conformal coating in industrial environments |
| J-STD-020 Level 1 moisture sensitivity | Enables direct placement without baking or dry-pack handling - reduces manufacturing overhead and floor-life constraints |
| RoHS and halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS directives - supports export to EU, Japan, and other regulated markets |
| Matte tin-plated leads | Ensures solderability per J-STD-002 and eliminates whisker risk per JESD 201 Class 2 - critical for automotive and telecom BOMs |
Applications
| LED Lighting Driver | USB-C Power Adapter |
|---|---|
Use Scenario: Rectifying 50/60Hz or high-frequency AC from flyback transformer secondary in constant-current LED drivers. IC Role / Device Role / Timing Role: Output-stage unidirectional current valve converting pulsating DC to smoothed DC for LED string biasing. Use Value: Low VF (≤1.15V) minimizes conduction loss in thermally constrained aluminum-core PCBs, extending driver lifetime. | Use Scenario: Input rectification in compact 30–65W USB-C PD adapters with universal AC input (90–264VAC). IC Role / Device Role / Timing Role: Primary-side bridge or single-diode rectifier in quasi-resonant flyback topologies. Use Value: 80A IFSM handles line surges and inrush without derating; SMB package fits tight layout constraints near EMI filters. |

Use Scenario: Generating +12V/-12V auxiliary rails for gate drivers and control ICs in motor drives and PLC power modules. IC Role / Device Role / Timing Role: Secondary-side rectifier in isolated auxiliary winding circuits with minimal filtering requirements. Use Value: 150°C TJ max and 10°C/W RθJL allow reliable operation in sealed enclosures with limited airflow. | Use Scenario: Low-cost, high-volume wall plug converters for consumer electronics (e.g., set-top boxes, routers). IC Role / Device Role / Timing Role: Full-wave or half-wave rectifier in cost-optimized linear or basic switching topologies. Use Value: DO-214AA (SMB) footprint ensures compatibility with legacy pick-and-place equipment and reduces retooling costs. |
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, 1.7V VF (max), TO-277 package | Higher voltage rating but higher VF and larger footprint - unsuitable for 50V designs where loss and space are critical | Select only if system requires >500V reverse blocking and can accommodate higher conduction loss |
| SB350-E3/5BT | 50V VRRM, 3A IF, 0.85V VF (typ), DO-214AA package, Schottky construction | Lower VF and faster recovery (≈10ns), but higher IR (1mA @ 25°C) and lower TJ max (125°C) | Prefer for efficiency-critical, low-voltage, low-temperature applications; avoid in high-ambient or high-reliability contexts |
Compared with STTH3L06S and SB350-E3/5BT, the S3ABHR5G offers optimal balance of low-cost, 50V-specific robustness, SMB compatibility, and 150°C thermal margin - making it ideal for cost-sensitive, space-constrained, and thermally demanding 50V rectification tasks.

FAQ
What is the maximum junction temperature rating for the S3ABHR5G?
The S3ABHR5G has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This allows sustained operation in high-ambient environments when thermal design accounts for its 10°C/W junction-to-lead resistance. The S3ABHR5G must not exceed this limit during steady-state or transient conditions to ensure reliability and longevity.
Is the S3ABHR5G RoHS and halogen-free compliant?
Yes, the S3ABHR5G is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the "Features" section of the Taiwan Semiconductor datasheet. This compliance applies to all materials including molding compound and matte tin-plated leads. The S3ABHR5G meets environmental requirements for global commercial and industrial deployments without restriction.
What does the marking code 'S3AB' indicate on the S3ABHR5G device?
The marking code 'S3AB' on the S3ABHR5G identifies it as the 50V variant within Taiwan Semiconductor's S3x rectifier family - 'S3' denotes 3A rating, 'A' indicates 50V VRRM, and 'B' specifies DO-214AA (SMB) package. The full orderable part S3ABHR5G includes additional suffixes denoting tape-and-reel packaging and green compound, per the official ordering information table.
Can the S3ABHR5G be used in place of a Schottky diode like SB350?
The S3ABHR5G is not a direct replacement for Schottky diodes such as SB350 due to its higher VF (1.15V vs. 0.85V typ) and slower trr (1500ns vs. ~10ns). While both are DO-214AA packaged 3A rectifiers, the S3ABHR5G's standard recovery behavior increases switching loss and EMI in high-frequency designs. Use S3ABHR5G only where its 150°C rating and lower IR outweigh Schottky trade-offs.
What is the moisture sensitivity level (MSL) of the S3ABHR5G?
The S3ABHR5G is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and requires no baking prior to reflow. This simplifies SMT assembly logistics and eliminates dry-pack handling costs. The S3ABHR5G's Level 1 rating is enabled by its hermetically molded DO-214AA (SMB) package and moisture-resistant passivation layer.
