Product details

Overview

SRF10150 from Taiwan Semiconductor is a 10A, 150V Schottky barrier rectifier in ITO-220AB package with dual-die configuration, 4.0°C/W junction-to-case thermal resistance, 1.00V max forward voltage at 5A/25°C, and 100µA max reverse leakage at rated VR/25°C. It serves as a high-efficiency output rectifier in DC-DC converters and industrial SMPS.

For engineers reviewing the SRF10150 datasheet, SRF10150 pinout, SRF10150 application, or SRF10150 equivalent, key selection criteria include its 150V VRRM rating, 120A IFSM surge capability, AEC-Q101 qualification option (SRF10150H), TJ = –55°C to +150°C operating range, and ITO-220AB mechanical compatibility with heatsink mounting.

Technical Context

The SRF10150 implements a dual-die Schottky structure optimized for low conduction loss in medium-voltage switching power supplies. Its 1.00V VF max at 5A/25°C and 4.0°C/W R_θJC support thermally constrained designs requiring stable 10A continuous operation up to 150°C junction temperature.

Rated for 150V repetitive peak reverse voltage (V_RRM) and 105V RMS reverse voltage, the device delivers 100µA max IR at 25°C and 5mA max IR at 125°C - enabling reliable blocking performance across automotive and industrial ambient temperature profiles.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	150 V - Maximum non-repetitive reverse voltage the device blocks without breakdown; defines upper limit for DC bus or output rail voltage selection.
I_F	10 A - Continuous average forward current rating at case temperature ≤75°C; determines minimum heatsink sizing for steady-state operation.
I_FSM	120 A - Peak non-repetitive surge current (8.3ms half-sine); supports inrush and transient overload tolerance in power-up sequences.
V_F max	1.00 V @ 5A, 25°C - Forward voltage drop per diode; directly impacts conduction loss (P_cond ≈ I_F × V_F) and thermal design margin.
R_θJC	4.0 °C/W - Junction-to-case thermal resistance; enables calculation of junction temperature rise (ΔT_J = P_diss × R_θJC) under known power dissipation.
I_R max	100 µA @ 150V, 25°C - Reverse leakage current per diode; critical for standby power budgeting and high-impedance sensing node integrity.
T_J max	+150 °C - Maximum allowable junction temperature; permits operation in under-hood or enclosed industrial environments without derating.

Pinout & Package

Package: ITO-220AB - Insulated TO-220 variant with internal isolation between collector (case) and emitter terminals; matte tin-plated leads compliant with J-STD-002 solderability; UL 94V-0 molding compound; 0.56 N·m max mounting torque; polarity marked on device body.

Pin/Terminal	Circuit Role	Design Meaning
Anode 1	Input terminal for first Schottky die	Connects to high-side switch node or transformer secondary in center-tapped configurations; requires trace width and copper area sufficient for 10A continuous current.
Cathode (Common)	Shared cathode connection for both dies	Electrically ties both diodes to output rail or ground return; must be routed with low-inductance, high-current path to minimize switching noise coupling.
Anode 2	Input terminal for second Schottky die	Enables dual-output or full-wave rectification; independent anode routing required to prevent cross-conduction in synchronous designs.
Case / Tab	Isolated metal thermal pad	Provides primary heat transfer path to heatsink; electrically isolated from all terminals per ITO-220AB construction; no electrical bias required.

Key Features

Feature	Design Value
Guard ring structure	Enhances edge termination robustness against voltage transients and localized field crowding, improving long-term reliability in noisy industrial bus environments.
AEC-Q101 qualification option	Available as SRF10150H - validated for automotive-grade temperature cycling, humidity, and mechanical shock per AEC-Q101 Rev D requirements.
Dual-die configuration	Enables single-package implementation of full-wave or dual-output rectification without discrete paralleling, reducing PCB footprint and interconnect inductance.
UL Recognized (E-326243)	Confirms compliance with UL 60747-5-1 for discrete semiconductors, supporting safety certification of end equipment in North American markets.
Halogen-free construction	Meets IEC 61249-2-21 - eliminates brominated flame retardants, aligning with RoHS and WEEE environmental compliance mandates for global OEM shipments.

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-10BQ015	10A, 150V; VF = 0.82V typ @ 5A/25°C; R_θJC = 3.0°C/W; TO-220AC package (non-isolated case)	Non-isolated case requires insulating hardware for heatsink mounting; lower VF improves light-load efficiency but higher cost.	Select when lower conduction loss and tighter thermal resistance are prioritized over isolation and cost.
ON Semiconductor MBR10150CT	10A, 150V; VF = 0.92V max @ 5A/25°C; R_θJC = 4.5°C/W; TO-220AB package (isolated case)	Same ITO-220AB isolation; slightly higher VF and worse thermal resistance than SRF10150; AEC-Q101 not offered.	Select when direct footprint compatibility with legacy TO-220AB layouts is required and AEC-Q101 is not needed.

Compared with VS-10BQ015 and MBR10150CT, the SRF10150 offers balanced trade-offs: superior isolation (ITO-220AB), AEC-Q101 availability (H version), and competitive VF/R_θJC, making it optimal for new industrial and automotive designs where safety certification and thermal predictability are critical.

FAQ

What is the maximum junction temperature rating for the SRF10150?

The SRF10150 has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet. This allows uninterrupted operation in high-ambient environments such as under-hood automotive locations or sealed industrial enclosures. The SRF10150 maintains specified electrical parameters up to this limit when thermal design adheres to its 4.0°C/W R_θJC specification.

Does the SRF10150 have AEC-Q101 qualification?

The base SRF10150 is not AEC-Q101 qualified, but the SRF10150H variant is explicitly listed as AEC-Q101 qualified in Taiwan Semiconductor's ordering information. The "H" suffix denotes full qualification per AEC-Q101 Rev D, including stress testing for temperature cycling, mechanical shock, and humidity. For automotive applications requiring qualification evidence, specify SRF10150H - the SRF10150 itself does not carry this certification.

What is the forward voltage specification for the SRF10150 at rated current?

The SRF10150 has a maximum forward voltage (V_F) of 1.00 V at 5A and 25°C junction temperature, as confirmed in the Electrical Specifications table. This value is measured per diode under pulsed conditions (PW = 0.3ms). At full 10A continuous current, actual V_F will increase due to self-heating; system-level thermal modeling using the 4.0°C/W R_θJC is required to estimate real-world conduction loss.

How does the SRF10150 differ from the SRF10100 in terms of voltage rating and thermal performance?

The SRF10150 is rated for 150V V_RRM, whereas the SRF10100 is rated for 100V V_RRM. Both share identical thermal performance: 4.0°C/W R_θJC, 120A I_FSM, and +150°C T_J max. However, the SRF10150 exhibits higher forward voltage (1.00V max vs. 0.90V max for SRF10100) and lower reverse leakage at 125°C (5mA vs. unspecified for SRF10100), reflecting process optimization for higher-voltage operation.

What packaging and marking format does the SRF10150 use?

The SRF10150 is supplied in ITO-220AB package with 50 units per tube. Marking includes "SRF10150" as the part code, "G" for green compound, a two-digit year and two-digit week date code (YWW), and a factory code "F". Polarity is indicated by a cathode band adjacent to the common cathode terminal, consistent with industry-standard Schottky rectifier marking conventions.
