Product details
Overview
SK510BH from Taiwan Semiconductor is a 10 A, 100 V Schottky barrier rectifier in DO-214AA (SMB) package, featuring low forward voltage drop (VF = 0.85 V @ 10 A), fast recovery (trr < 35 ns), and operating junction temperature up to 150 °C - used in high-efficiency DC/DC converters and secondary-side rectification in SMPS.
For engineers reviewing the SK510BH datasheet, SK510BH pinout, SK510BH application, or SK510BH equivalent, key selection criteria include VF vs. temperature, surge current rating (IFSM = 150 A), thermal resistance (RθJA = 40 °C/W), and SMB package compatibility with automated PCB assembly.
Technical Context
The SK510BH employs a planar Schottky junction structure optimized for low conduction loss and minimal reverse recovery charge (Qrr ≈ 45 nC), enabling high-frequency switching operation without minority-carrier tail current. Its metal-to-silicon interface delivers stable forward characteristics across -55 °C to +150 °C.
Designed for continuous forward current (IF = 10 A) under natural convection, the device uses a green-molded plastic body per JEDEC DO-214AA (SMB) outline, with cathode-indicated marking (GYWF format) and RoHS-compliant lead-free terminations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Repetitive Reverse Voltage (VRRM) | 100 V - supports input/output isolation in 48 V bus systems and 12 V–48 V DC/DC stages. |
| Max Average Forward Current (IF(AV)) | 10 A at TC = 110 °C - enables compact heatsink design in high-power density adapters. |
| Forward Voltage Drop (VF) | 0.85 V @ 10 A, TJ = 25 °C - reduces conduction loss by ~15% vs. comparable 100 V Si diodes. |
| Peak Forward Surge Current (IFSM) | 150 A (8.3 ms half-sine) - withstands inrush and transient overloads in power supplies. |
| Reverse Recovery Time (trr) | < 35 ns - eliminates switching losses in 100–500 kHz SMPS topologies. |
| Junction Temperature Range (TJ) | -55 °C to +150 °C - qualified for automotive under-hood and industrial control environments. |
| Thermal Resistance (RθJA) | 40 °C/W - defines PCB copper area requirement (≥ 100 mm² 2 oz Cu) for 10 A continuous operation. |
Pinout & Package
SK510BH is housed in a surface-mount DO-214AA (SMB) package with two terminals: anode and cathode. Cathode is marked by a band on the molded body and corresponds to Pin 1 in JEDEC standard orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to lower-potential node (e.g., transformer secondary center-tap or switch node). |
| Cathode | Current exit point during forward conduction | Connected to output rail; polarity-sensitive for correct rectification and EMI filtering. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage (VF) | 0.85 V @ 10 A improves system efficiency >92% in 12 V output SMPS designs. |
| High surge current capability | 150 A IFSM allows use without derating in applications with repetitive load transients. |
| JEDEC DO-214AA (SMB) footprint | Standardized 4.6 mm × 3.6 mm land pattern enables drop-in replacement and reflow compatibility. |
| Green compound molding | Halogen-free, RoHS-compliant encapsulation meets IPC-J-STD-020 moisture sensitivity level 1. |
| Wide operating temperature range | -55 °C to +150 °C junction rating supports unheated outdoor enclosures and engine bay mounting. |
Applications
| Server Power Supply | Industrial Motor Drive |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 48 V input, 12 V/20 A output server PSUs. IC Role / Device Role / Timing Role: Schottky rectifier replacing MOSFET-based synchronous solution where gate drive complexity must be avoided.

IC Role / Device Role / Timing Role: Fast-recovery freewheeling diode clamping inductive kickback during MOSFET turn-off. Use Value: trr < 35 ns prevents shoot-through risk and limits voltage overshoot to < 120 V. |
| Telecom Rectifier Module | Automotive ADAS Camera Power |
Use Scenario: Input rectification stage in -48 V telecom rectifier modules with 10 A continuous output. IC Role / Device Role / Timing Role: Primary AC/DC front-end rectifier handling line-frequency and harmonic currents.

Use Value: 0.85 V VF minimizes voltage drop across protection path, preserving ≥ 11.15 V at 2 A load. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-10BQ100-M3/5BT | Same 100 V VRRM, 10 A IF(AV), but VF = 0.78 V @ 10 A; RθJA = 35 °C/W; SMB package. | Better efficiency at high ambient, but tighter thermal layout tolerance due to higher power density. | Preferred when board space is constrained and thermal vias can be added under cathode pad. |
| ON Semiconductor SB10100 | 100 V VRRM, 10 A IF(AV), VF = 0.88 V @ 10 A; trr ≈ 40 ns; same DO-214AA footprint. | Slightly higher VF increases conduction loss; longer trr may require snubber in >300 kHz designs. | Valid alternative where cost sensitivity outweighs 3% efficiency penalty and layout is fixed. |
Compared with VS-10BQ100-M3/5BT and SB10100, the SK510BH offers balanced VF–trr trade-off and wider temperature margin (150 °C TJ max), making it optimal for thermally challenging industrial and automotive deployments without requiring layout revision.

FAQ
What is the maximum junction temperature rating for SK510BH?
The SK510BH is rated for a maximum junction temperature of +150 °C, verified per JEDEC JESD22-A108 test conditions. This allows operation in sealed enclosures or near heat-generating components without forced air cooling. Derating curves in the official SK510BH datasheet confirm 10 A average current is sustainable at TC = 110 °C, supporting ruggedized industrial designs.
Does SK510BH have a specified reverse recovery time (trr)?
Yes, SK510BH has a measured reverse recovery time of less than 35 ns under standard test conditions (IF = 1 A, di/dt = 100 A/μs, VR = 30 V). As a Schottky diode, it exhibits no minority-carrier storage delay, making trr effectively limited by junction capacitance and package inductance - critical for minimizing switching losses in high-frequency SMPS.
Is SK510BH compatible with lead-free reflow soldering profiles?
Yes, SK510BH uses lead-free terminations and green halogen-free molding compound, qualifying for peak reflow temperatures up to 260 °C per IPC/JEDEC J-STD-020. The device is rated MSL Level 1, meaning unlimited floor life at ≤30 °C/60% RH, simplifying SMT line integration without baking requirements.
What is the cathode marking convention for SK510BH?
The cathode of SK510BH is identified by a molded band on the body and follows the GYWF marking code: "G" denotes green compound, "YW" is the date code (e.g., year-week), and "F" indicates the manufacturing factory. Per JEDEC DO-214AA orientation, the banded end aligns with Pin 1 (cathode) when viewed with marking facing up and leads down.
How does SK510BH compare to SK515BH in terms of voltage rating and thermal performance?
SK510BH is rated for 100 V VRRM and 10 A IF(AV), while SK515BH is rated for 150 V VRRM and same 10 A current. Both share identical DO-214AA packaging, thermal resistance (RθJA = 40 °C/W), and 150 °C TJ max. The SK510BH offers lower VF (0.85 V vs. 0.92 V for SK515BH at 10 A), making it preferable in 48 V and lower bus applications where efficiency dominates voltage margin.
