Product details
Overview
STPS30L60CW from Vishay is a center-tap Schottky rectifier optimized for low forward voltage drop (0.56 V @ 15 A, TJ = 125°C), 60 V reverse voltage rating, and 30 A average forward current per leg in TO-247AC package. It operates up to 150°C junction temperature and serves as a freewheeling diode or reverse-battery protection device in high-frequency DC/DC converters.
For engineers reviewing the STPS30L60CW datasheet, STPS30L60CW pinout, STPS30L60CW application, or STPS30L60CW equivalent, key selection criteria include its dual-anode center-tap configuration, thermal resistance of 2.20°C/W (per leg), 1020 A non-repetitive surge capability, and suitability for industrial-grade switching power supplies requiring ruggedness and low conduction loss.
Technical Context
The STPS30L60CW integrates two Schottky diodes sharing a common cathode terminal in a single TO-247AC package, enabling center-tapped rectification without external interconnection. Its proprietary barrier technology ensures stable operation at 150°C junction temperature while maintaining low VF and moderate IR.
Designed for high-frequency switching applications, it exhibits 720 pF junction capacitance per leg at 5 V and 7.5 nH series inductance - parameters critical for minimizing switching losses and EMI in SMPS topologies such as full-bridge and push-pull converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) per leg | 30 A, rated for 50% duty cycle rectangular waveform at TC = 112°C - defines continuous conduction capability in high-duty-cycle converters |
| VRRM | 60 V - maximum DC reverse blocking voltage; sets upper limit for input/output voltage rails in buck, flyback, or OR-ing circuits |
| VF @ 15 A, TJ = 125°C | 0.56 V - low conduction loss enables >95% efficiency in 12–48 V output stages with minimal heatsinking |
| RthJC (per leg) | 2.20 °C/W - thermal path from junction to case determines minimum heatsink requirement for 30 A operation |
| IFSM (5 μs sine) | 1020 A - surge rating supports robust startup and fault tolerance in motor drives and UPS systems |
| IRM @ 25°C | 0.48 mA per leg - moderate leakage allows use in battery-powered reverse-polarity protection without excessive standby drain |
| CT @ 5 V | 720 pF per leg - low capacitance preserves fast switching edge integrity and reduces capacitive turn-on loss |
Pinout & Package
TO-247AC (JEDEC TO-3P) package with isolated mounting tab; mechanical strength enhanced by high-purity, high-temperature epoxy encapsulation. Pin 1: Anode A, Pin 2: Common Cathode, Pin 3: Anode B - center-tap configuration enables dual-output or synchronous rectification with shared return path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode A | First Schottky anode; connects to primary-side switch node in push-pull or full-bridge rectifiers |
| Pin 2 | Common Cathode | Shared cathode output; serves as DC output rail reference point for both legs |
| Pin 3 | Anode B | Second Schottky anode; ties to complementary switch node for balanced current sharing |
Key Features
| Feature | Design Value |
|---|---|
| Center-tap dual-diode integration | Eliminates discrete wiring between two Schottky dies, reducing parasitic inductance and layout complexity in transformer-coupled outputs |
| 150°C maximum junction temperature | Enables operation in sealed industrial enclosures without derating at ambient up to 85°C with proper heatsinking |
| Guard ring structure | Improves avalanche ruggedness and long-term reliability under repetitive transient overvoltage conditions |
| High-frequency optimized design | Low CT and LS values support clean switching waveforms in converters operating above 300 kHz |
| Moisture-resistant epoxy encapsulation | Meets IPC/JEDEC J-STD-020 moisture sensitivity level 1 - suitable for standard reflow without baking |
Applications
| Switch-Mode Power Supply Output Rectification | Reverse Battery Protection |
|---|---|
Use Scenario: Used in secondary-side rectification of 24–48 V output DC/DC converters in telecom and server PSUs. IC Role / Device Role / Timing Role: Dual-anode Schottky rectifier providing low-loss, center-tapped DC output with shared cathode return. Use Value: 0.56 V VF at 15 A reduces conduction loss by ~35% vs. comparable 60 V Si diodes, improving system efficiency and thermal margin. | Use Scenario: Placed in series with vehicle battery input to prevent damage during accidental reverse polarity connection. IC Role / Device Role / Timing Role: Low-VF, high-current Schottky acting as unidirectional current gate with minimal forward drop. Use Value: 0.56 V VF limits voltage loss to <1% at 30 A, preserving battery runtime and avoiding thermal shutdown in automotive ECUs. |
| Freewheeling Diode in Motor Drives | OR-ing Diode in Redundant Power Systems |
Use Scenario: Mounted across inductive loads in BLDC motor controllers to clamp back-EMF during PWM off-time. IC Role / Device Role / Timing Role: Fast-recovery Schottky freewheeling path with 1020 A IFSM surge rating. Use Value: 7.5 nH LS and 720 pF CT minimize voltage overshoot and ringing, reducing MOSFET stress and EMI filter burden. | Use Scenario: Employed in parallel 12 V power inputs for industrial PLCs to isolate faults and enable seamless switchover. IC Role / Device Role / Timing Role: Center-tap configured as dual independent OR-ing diodes sharing a common output rail. Use Value: Matched VF characteristics between legs ensure balanced current sharing and prevent thermal runaway during load transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS30H60CG | Same TO-247AC package, 60 V, but higher VF (0.72 V @ 15 A) and lower TJ max (175°C vs. 150°C); no center-tap configuration - discrete dual-die | Requires external interconnect for center-tap function; less compact layout | Select when higher surge rating (1200 A) and wider TJ range outweigh VF penalty and layout overhead |
| VS-30CPH06-M3 | TO-247 package, 60 V, 30 A, center-tap, but VF = 0.65 V @ 15 A and RthJC = 2.5°C/W - higher thermal resistance | Compatible pinout and footprint; same dual-anode/common-cathode topology | Choose when Vishay supply continuity is constrained and identical mechanical fit is required despite 16% higher conduction loss |
Compared with STPS30L60CW, STPS30H60CG trades lower forward voltage for higher surge capability and wider temperature range but lacks integrated center-tap convenience, while VS-30CPH06-M3 offers pin-compatible replacement with measurable efficiency and thermal penalties.

FAQ
What is the pin configuration of the STPS30L60CW?
The STPS30L60CW uses a three-pin TO-247AC package with Pin 1 = Anode A, Pin 2 = Common Cathode, and Pin 3 = Anode B. This center-tap arrangement allows both Schottky diodes to share a single cathode output, simplifying PCB layout in transformer-coupled or dual-rail rectifier designs. The pinout is standardized per JEDEC outline TO-3P and verified in Vishay Bulletin PD-20625 rev. A.
Does the STPS30L60CW support 150°C continuous operation?
Yes, the STPS30L60CW is rated for continuous operation up to 150°C junction temperature, enabled by proprietary barrier technology and high-temperature epoxy encapsulation. Its RthJC of 2.20°C/W (per leg) and derated IF(AV) curve in Figure 5 confirm stable performance at this limit when mounted on an adequately sized heatsink with greased interface.
What is the maximum surge current rating for the STPS30L60CW?
The STPS30L60CW has a non-repetitive peak surge current rating of 1020 A for a 5 μs sine pulse, as specified in its Absolute Maximum Ratings table. This value applies per leg and reflects capability under short-duration overload conditions such as inrush or fault events in motor drive or UPS applications.
Is the STPS30L60CW RoHS-compliant and lead-free?
Yes, the STPS30L60CW is RoHS-compliant and lead-free. The "CW" suffix in the part number denotes TO-247 package, and Vishay's documentation confirms Pb-free construction per JEDEC standards. No lead-based solder or terminations are used, and the device meets EU Directive 2011/65/EU requirements.
How does the STPS30L60CW compare to standard silicon rectifiers in efficiency?
The STPS30L60CW achieves significantly higher efficiency than standard silicon rectifiers due to its Schottky architecture: 0.56 V forward voltage at 15 A and 125°C versus ~1.1 V for comparable Si diodes. This cuts conduction losses nearly in half, directly improving converter efficiency - especially critical in high-current, high-duty-cycle applications like server PSUs where thermal management is constrained.
