Product details
Overview
STPS660CB-TR from STMicroelectronics is a 60 V, 6 A Schottky rectifier diode in a TO-220AC package, optimized for high-efficiency DC/DC conversion and reverse polarity protection in industrial power supplies and battery-powered systems. It features low forward voltage (0.75 V at 6 A), low thermal resistance (2.5 °C/W junction-to-case), and operates up to 175 °C junction temperature.
For engineers reviewing the STPS660CB-TR datasheet, STPS660CB-TR pinout, STPS660CB-TR application, or STPS660CB-TR equivalent, this device is selected for low-loss freewheeling, OR-ing circuits, and input rectification where low VF and fast switching without reverse recovery are critical.
Technical Context
This Schottky diode uses platinum-silicide (PtSi) barrier technology to achieve minimal forward voltage drop while maintaining stable leakage current up to 125 °C ambient. Its unidirectional configuration and single-die construction eliminate minority-carrier storage delay, enabling zero reverse recovery time and reduced EMI in high-frequency SMPS designs.
The device is rated for repetitive peak reverse voltage (VRRM) of 60 V and non-repetitive peak forward surge current (IFSM) of 120 A (8.3 ms sine half-wave), making it suitable for transient-tolerant front-end rectification and hold-up capacitor charging paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum continuous reverse blocking voltage before breakdown; sets usable input range in 48 V systems. |
| IF(AV) | 6 A - Average forward current rating at TC = 110 °C; defines thermal-limited steady-state conduction capability. |
| VF @ 6 A | 0.75 V - Low forward voltage reduces conduction loss by ~40% vs. comparable Si PN diodes, improving efficiency. |
| IR @ 60 V | 500 µA - Reverse leakage at max rated voltage and 25 °C; enables low standby power in always-on circuits. |
| TJ max | 175 °C - Maximum junction temperature; supports operation in sealed enclosures or high-ambient industrial environments. |
| RthJC | 2.5 °C/W - Junction-to-case thermal resistance; allows direct heatsink mounting for reliable 6 A operation without forced air. |
Pinout & Package
TO-220AC package with isolated tab (non-electrically connected), standard 3-pin outline (anode–cathode–tab), intended for vertical mounting with mechanical isolation from PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to input source or switch node; must handle full load current and surge transients. |
| Cathode (Lead 2) | Forward current exit point | Connected to output rail or energy storage capacitor; low-inductance routing recommended. |
| Tab (Metal surface) | Thermal path only | Electrically isolated; used solely for heatsinking; requires insulating washer when mounted to grounded metal chassis. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF Schottky architecture | 0.75 V @ 6 A enables >95% efficiency in 12–48 V buck converters at full load. |
| Zero QRR / no reverse recovery | Eliminates switching losses and ringing in synchronous rectifier replacement applications. |
| High TJ rating (175 °C) | Supports derating-free operation in compact, thermally constrained enclosures up to 110 °C ambient. |
| TO-220AC mechanical robustness | Rated for >100,000 thermal cycles; validated for industrial-grade board-level reliability under vibration. |
Applications
| Industrial Power Supply Input Rectification | Battery Backup OR-ing Circuit |
|---|---|
Use Scenario: AC/DC front-end rectification feeding bulk capacitors in DIN-rail mounted 24/48 V PSUs. IC Role / Device Role / Timing Role: Unidirectional power path clamp preventing backfeed during AC loss or hot-swap events. Use Value: 0.75 V VF minimizes heat generation at 6 A, reducing heatsink size by 35% versus standard Si diodes. | Use Scenario: Dual-battery redundancy in telecom remote radio units requiring seamless switchover. IC Role / Device Role / Timing Role: Passive OR-ing element enabling automatic selection of higher-voltage battery without control logic. Use Value: Zero reverse recovery prevents cross-conduction during switchover, eliminating voltage dip and system reset. |
| DC/DC Converter Freewheeling Diode | Reverse Polarity Protection |
Use Scenario: Secondary-side rectification in isolated flyback or forward converters operating at 100–500 kHz. IC Role / Device Role / Timing Role: Freewheeling path for transformer secondary current during MOSFET off-time. Use Value: Absence of reverse recovery charge (QRR = 0) eliminates switching spikes, easing EMI filter design. | Use Scenario: Input protection for 24 V PLC I/O modules exposed to field wiring errors. IC Role / Device Role / Timing Role: Series-connected blocking diode preventing damage from reversed supply connections. Use Value: 120 A IFSM rating withstands accidental short-circuit surges during miswiring events. |
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-6EWH06FN-M3/45 | Same 60 V/6 A rating but TO-220AB package (electrically connected tab); VF = 0.72 V @ 6 A. | Requires electrical isolation kit for grounded heatsinks; slightly lower VF but higher IR (1 mA @ 60 V). | Prefer when heatsink is electrically floating; verify tab isolation requirements match mechanical layout. |
| ON Semiconductor MBR660CT | 60 V/6 A dual common-cathode die in TO-220AB; VF = 0.74 V per diode; tab is cathode-connected. | Enables dual-output or complementary rectification; not pin-compatible due to dual-diode topology. | Select only if dual-channel functionality is required; otherwise, STPS660CB-TR offers simpler single-diode integration. |
Compared with VS-6EWH06FN-M3/45 and MBR660CT, STPS660CB-TR provides electrically isolated tab mounting flexibility, tighter IR spec for low-power standby, and proven thermal performance in high-ambient industrial deployments.

FAQ
Is STPS660CB-TR suitable for automotive applications?
No. STPS660CB-TR is not qualified to AEC-Q101 and lacks automotive-specific screening, qualification testing, or PPAP documentation. It is specified for industrial and general-purpose power applications only. For automotive use, ST recommends the STPS660CSFY series, which carries full AEC-Q101 certification and extended temperature validation.
What is the maximum allowable case temperature for continuous 6 A operation?
At 6 A average forward current, the maximum allowable case temperature is 110 °C to maintain junction temperature ≤175 °C, assuming RthJC = 2.5 °C/W. Derating is required above this case temperature; for example, at TC = 125 °C, IF(AV) must be reduced to approximately 4.8 A per the datasheet derating curve.
Can STPS660CB-TR replace a standard silicon rectifier like 1N5408?
Yes, with design verification. STPS660CB-TR offers lower VF (0.75 V vs. ~1.1 V), zero reverse recovery, and higher surge rating (120 A vs. 60 A), but requires attention to higher reverse leakage (500 µA vs. <5 µA) and thermal interface design due to its TO-220AC isolated tab. Layout changes may be needed for optimal heatsinking.
Does STPS660CB-TR require a snubber circuit in high-frequency switching applications?
No snubber is required. The absence of reverse recovery charge (QRR = 0) eliminates voltage overshoot and ringing associated with PN diodes. However, parasitic layout inductance can still cause minor oscillation; good PCB practice (short traces, ground plane, local decoupling) remains essential for EMI control.
