Product details
Overview
SK56C R6G from Taiwan Semiconductor is a 5A, 60V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, optimized for high-efficiency switching power supplies with low forward voltage (0.75 V at 5 A, 25°C) and high surge capability (120 A IFSM). It features guard-ring overvoltage protection, moisture sensitivity level 1, and RoHS/halogen-free compliance.
For engineers reviewing the SK56C R6G datasheet, SK56C R6G pinout, SK56C R6G application, or SK56C R6G equivalent, this device is selected for high-frequency DC/DC converters where low conduction loss, thermal robustness (TJ max = 150°C), and automated placement compatibility are critical - especially in compact adapter and LED driver designs requiring stable 60V reverse blocking.
Technical Context
The SK56C R6G implements a single-die Schottky junction with metal–semiconductor contact enabling fast recovery (no minority-carrier storage) and zero reverse recovery charge (QRR ≈ 0). Its 60 V VRRM rating targets mid-voltage SMPS outputs, while the 13 °C/W junction-to-lead thermal resistance supports PCB-mounted thermal management without heatsinks under 5 A continuous load.
Designed for operation across –55°C to +150°C junction temperature range, it maintains ≤0.5 mA reverse leakage at 25°C and ≤10 mA at 100°C under rated VR, ensuring stable performance in thermally constrained lighting and converter applications where thermal runaway must be avoided.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage; defines safe operating margin for 48 V nominal output rails. |
| IF | 5 A - Continuous forward current; supports typical 60 W–100 W converter output stages. |
| VF @ 5 A, 25°C | 0.75 V - Low conduction loss reduces power dissipation to ~3.75 W, easing thermal design. |
| IFSM (8.3 ms) | 120 A - Withstands inrush and transient surges common during cold-start or line transients. |
| IR @ 60 V, 25°C | ≤0.5 mA - Minimal leakage preserves efficiency in standby and light-load conditions. |
| RθJL | 13 °C/W - Enables direct PCB copper pad heat sinking; allows >4 W dissipation before exceeding TJ max. |
| TJ Range | –55°C to +150°C - Rated for industrial ambient environments and enclosed power modules. |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, cathode-indicated by molded band. Case meets UL 94V-0; matte tin-plated leads comply with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward current flow | Connected to transformer secondary or switch node; low-resistance path minimizes conduction loss. |
| Cathode | Output terminal for forward current flow | Marked by band; ties to output capacitor and feedback network; polarity-sensitive for correct rectification. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Enhances ruggedness against transient overvoltage events without external snubbers. |
| Moisture sensitivity level 1 | Eliminates bake requirements prior to reflow; compatible with standard SMT assembly lines. |

| RoHS and halogen-free | Meets global environmental compliance mandates for consumer, industrial, and lighting end equipment. |
Applications
| AC-DC Adapter Output Rectification | LED Driver Secondary-Side Rectification |
|---|---|
Use Scenario: 48 V input, 12 V/3 A output flyback adapter for IoT gateways. IC Role / Device Role / Timing Role: Primary output rectifier replacing slower diodes to reduce losses and improve efficiency above 88%. Use Value: 0.75 V VF cuts conduction loss by ~35% vs. standard FR107, directly improving thermal margin and no-load power. |
Use Scenario: Constant-current LED driver powering 10× 3 V LEDs in series (30 V string) from 36 V bus. IC Role / Device Role / Timing Role: Secondary-side freewheeling rectifier in buck-derived topology. Use Value: 60 V VRRM provides 20% safety margin over 30 V string; low IR ensures stable dimming at low PWM duty cycles. |
| USB-C PD Power Delivery Module | Industrial DC/DC Converter Output Stage |
Use Scenario: 20 V/5 A USB-C PD source module with dual-phase synchronous rectification. IC Role / Device Role / Timing Role: Standby or auxiliary rectifier in hold-up or sense path; not main switching element. Use Value: 120 A IFSM handles hot-plug surges; DO-214AB footprint enables compact layout adjacent to controller IC. |
Use Scenario: 24 V input, 5 V/5 A isolated DC/DC converter for PLC I/O modules. IC Role / Device Role / Timing Role: Output rectifier in forward converter secondary winding. Use Value: 150°C TJ rating ensures reliability under 70°C ambient + self-heating; RθJL = 13 °C/W enables 4-layer board use without thermal vias. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SS56HE3/5AT | Same 60 V VRRM, 5 A IF, DO-214AB package; VF = 0.72 V (typ) at 5 A - slightly lower conduction loss. | Identical mounting and thermal profile; validated in lighting drivers per Vishay AN-9003. | Preferred when <0.03 V VF reduction justifies sourcing from alternate vendor; identical layout. |
| ON Semiconductor SB560-E3/54 | 60 V VRRM, 5 A IF, DO-214AB; VF = 0.78 V (max) at 5 A - marginally higher conduction loss. | Higher IR (1.0 mA max at 25°C) may impact light-load efficiency in battery-backed systems. | Valid alternative where cost sensitivity outweighs 0.03 V VF penalty; requires no PCB change. |
Compared with SK56C R6G, SS56HE3/5AT offers marginally better conduction efficiency but shares identical thermal and layout constraints, while SB560-E3/54 trades 0.03 V higher VF for broader distributor availability - both require no schematic or footprint modification.

FAQ
What is the maximum junction temperature rating for the SK56C R6G?
The SK56C R6G has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table in TSC's S2311 datasheet. This rating enables reliable operation in enclosed power supplies and industrial environments where ambient temperatures exceed 70°C. Derating curves confirm usable current capacity down to 3.5 A at 125°C case temperature, making SK56C R6G suitable for thermally demanding applications without forced air cooling.
Does the SK56C R6G have a specified reverse recovery time (trr)?
No - the SK56C R6G is a Schottky barrier rectifier and exhibits no minority-carrier storage, so reverse recovery time (trr) is effectively zero. Its behavior is governed by junction capacitance (typically ~120 pF at 4 V bias) and parasitic inductance, not carrier recombination. This eliminates switching losses associated with trr and makes SK56C R6G ideal for high-frequency (>100 kHz) topologies where conventional PN diodes would incur significant recovery loss.
Is the SK56C R6G lead-free and RoHS compliant?
Yes - the SK56C R6G is fully RoHS compliant and halogen-free, as confirmed in the "Features" section of TSC's official documentation (Version S2311). Its matte tin-plated leads meet J-STD-002 solderability standards, and the molding compound complies with UL 94V-0 flammability rating. No lead or brominated flame retardants are used in its construction.
What is the cathode marking convention for the SK56C R6G?
The cathode of the SK56C R6G is indicated by a molded band on the DO-214AB (SMC) package body, positioned near one end of the device. Per mechanical data in the S2311 datasheet, this band aligns with the cathode terminal - the lead opposite the banded end is the anode. Correct orientation is essential to prevent reverse-bias failure in circuit operation.
Can the SK56C R6G replace the SK55C in an existing design?
Yes - the SK56C R6G is a direct upgrade from SK55C, sharing identical DO-214AB package, 5 A IF rating, and 120 A IFSM. The key difference is VRRM: SK55C is rated for 50 V, while SK56C R6G is rated for 60 V. Substituting SK56C R6G improves reverse voltage margin by 20% with no layout or thermal changes required, provided the original design operated below 50 V reverse stress.
