Product details
Overview
SR30150PT from Taiwan Semiconductor is a 30A, 150V Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring dual-die construction, 1.00V forward voltage at 15A/25°C, 500µA reverse current at rated VR/25°C, and 300A surge capability - deployed in high-efficiency DC-DC converters and industrial SMPS.
For engineers reviewing the SR30150PT datasheet, SR30150PT pinout, SR30150PT application, or SR30150PT equivalent, key selection criteria include VRRM=150V, IF=30A, TJ max=150°C, RθJC=1.5°C/W, and AEC-Q101 qualification status where specified.
Technical Context
This device operates as a single-phase, dual-die Schottky rectifier optimized for high-current, low-VF switching applications. Its 150V VRRM rating supports wide-input DC-DC stages, while the 1.00V VF at 15A/25°C and 10mA IR at 150V/100°C reflect trade-offs between voltage blocking and conduction loss.
The TO-247AD package enables high thermal dissipation (RθJC = 1.5°C/W), and the guard ring structure provides overvoltage protection. It is rated for junction temperatures up to +150°C, with storage range from −55°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse voltage the device blocks without breakdown |
| IF | 30 A - Continuous average forward current rating under specified thermal conditions |
| IFSM | 300 A - Non-repetitive peak surge current (8.3 ms half-sine) the device withstands |
| VF @ 15A, 25°C | 1.00 V - Forward voltage drop per diode, directly impacting conduction loss and thermal design |
| IR @ 150V, 25°C | 500 µA - Reverse leakage per diode, critical for standby power and high-impedance bias networks |
| TJ max | +150 °C - Maximum allowable junction temperature, enabling operation in high-ambient environments |
| RθJC | 1.5 °C/W - Thermal resistance from junction to case, defining heatsink sizing requirements |
Pinout & Package
Package: TO-247AD (TO-3P), 3-terminal through-hole package with isolated mounting tab; matte tin-plated leads, UL 94V-0 molding compound, polarity marked on case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input terminal for first Schottky die | Connects to high-side switching node in dual-output or interleaved topologies |

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-30CPH15-M3 | Same 150V VRRM, 30A IF, TO-247AC package; VF = 0.92V @ 15A/25°C; no AEC-Q101 option | Higher efficiency at mid-load but lacks guard ring and automotive qualification | Select when lower VF is prioritized and automotive qualification is not required |
| ON Semiconductor MBR30H150CT | 150V VRRM, 30A IF, TO-220AB package; VF = 0.95V @ 15A/25°C; common-cathode dual die, no AEC-Q101 | Lower thermal performance (RθJC ≈ 3.0°C/W); unsuitable for >60°C ambient without large heatsink | Select for cost-sensitive, lower-power applications where TO-220 footprint is preferred |
Compared with VS-30CPH15-M3 and MBR30H150CT, the SR30150PT offers superior thermal management (1.5°C/W), integrated overvoltage protection via guard ring, and AEC-Q101-qualified variants - making it optimal for high-reliability, thermally demanding industrial and automotive-derived power systems.

FAQ
What is the maximum junction temperature rating for the SR30150PT?
The SR30150PT has a maximum junction temperature (TJ max) of +150°C, validated per its absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed industrial power supplies or telecom rectifier modules. Derating curves in the datasheet define safe IF limits above 25°C case temperature, and thermal design must respect the 1.5°C/W junction-to-case resistance to avoid exceeding this limit during continuous 30A operation.
Does the SR30150PT have AEC-Q101 qualification?
The SR30150PT itself is not automatically AEC-Q101 qualified; however, the variant SR30150PTH - identical in electrical and thermal specs but with "H" suffix - is explicitly AEC-Q101 qualified per ordering information. Engineers requiring automotive-grade reliability must specify SR30150PTH and verify qualification status via Taiwan Semiconductor's official documentation and lot traceability reports.
What is the forward voltage specification for the SR30150PT at operating conditions?
The SR30150PT exhibits a typical forward voltage (VF) of 1.00 V per diode at IF = 15 A and TJ = 25°C, as confirmed in the Electrical Specifications table. At higher junction temperatures (e.g., 100°C), VF decreases slightly (~0.92 V), while at full-rated 30A, VF rises due to resistive heating - actual system-level VF depends on thermal management and duty cycle.
How is the dual-die configuration implemented in the SR30150PT package?
The SR30150PT integrates two independent Schottky dies in a single TO-247AD (TO-3P) package with three terminals: Anode 1, Anode 2, and a shared Cathode. This common-cathode dual-anode topology enables flexible use in interleaved, dual-output, or redundancy-configured power stages - eliminating the need for external paralleling and reducing layout parasitics compared to discrete dual-diode solutions.
What packaging and marking details apply to the SR30150PT?
The SR30150PT is supplied in TO-247AD (TO-3P) package with matte tin-plated leads, UL 94V-0 molding compound, and polarity marked on the case. Marking includes "SR30150PT", green compound indicator (G), date code (YWW), and factory code (F). Packing is 30 units per tube, and lead finish complies with J-STD-002 for solderability.
