Product details

Overview

SRS20150H from Taiwan Semiconductor is a 150 V, 20 A Schottky barrier surface-mount rectifier in TO-263AB (D2PAK) package, featuring 1.02 V forward voltage at 10 A and 25°C, 100 µA reverse leakage at rated VR and 25°C, and AEC-Q101 qualification for automotive-grade reliability-used in reverse battery protection and DC/DC converters.

For engineers reviewing the SRS20150H datasheet, SRS20150H pinout, SRS20150H application, or SRS20150H equivalent, key selection criteria include peak reverse voltage (150 V), surge current capability (200 A), junction-to-case thermal resistance (1.5 °C/W), TJ max rating (150°C), and RoHS/halogen-free compliance for automotive and industrial power systems.

Technical Context

The SRS20150H employs dual-die construction in a single TO-263AB (D2PAK) package with guard ring structure for overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its 150 V V_RRM and 100 µA I_R at 25°C reflect optimized high-voltage Schottky design trade-offs versus lower-voltage variants in the family.

Thermal performance is defined by R_θJC = 1.5 °C/W and maximum junction temperature of +150°C, enabling operation in high-power-density DC/DC stages where thermal management is critical. The device meets JESD201 Class 2 whisker resistance and moisture sensitivity level 1 per J-STD-020.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	150 V - Maximum repetitive reverse blocking voltage; defines upper limit for safe operation in reverse-biased conditions.
I_F	20 A - Continuous average forward current; determines steady-state power handling in freewheeling or rectification paths.
I_FSM	200 A - Non-repetitive surge current (8.3 ms half-sine); supports transient overload tolerance during startup or fault events.
V_F @ 10 A, 25°C	1.02 V - Forward voltage drop; directly impacts conduction loss and thermal rise in high-current switching nodes.
I_R @ V_R, 25°C	100 µA - Reverse leakage current at rated voltage; critical for low-power standby and reverse-polarity protection integrity.
R_θJC	1.5 °C/W - Junction-to-case thermal resistance; enables accurate heatsink sizing for 20 A continuous operation without exceeding T_J = 150°C.
T_J max	+150°C - Maximum allowable junction temperature; permits extended operation in under-hood automotive environments.

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-20CPH15-M3	Same 150 V V_RRM, 20 A I_F, but TO-247AC package; higher R_θJC (2.0 °C/W) and no AEC-Q101 qualification.	Requires larger PCB footprint and additional heatsinking; not approved for automotive use.	Select when mechanical mounting constraints favor through-hole or when AEC-Q101 is not required.
ON Semiconductor MBR20150CT	150 V V_RRM, 20 A I_F, TO-220AB package; VF = 1.1 V @ 10 A, IR = 200 µA @ 25°C, no AEC-Q101.	Larger thermal resistance and higher leakage reduce efficiency in compact, high-reliability designs.	Consider for cost-sensitive industrial applications where automotive qualification and ultra-low leakage are not mandatory.

Compared with VS-20CPH15-M3 and MBR20150CT, the SRS20150H delivers superior thermal performance (1.5 °C/W), lower leakage (100 µA), and automotive qualification in a surface-mount D2PAK package-making it optimal for space-constrained, high-reliability 12–48 V power systems.

FAQ

What is the maximum junction temperature rating for the SRS20150H?

The SRS20150H has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in the official datasheet. This allows reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves confirm 20 A continuous current is sustainable up to case temperatures of 110°C when mounted on adequate copper area. The SRS20150H must not exceed this limit to maintain long-term reliability and avoid parametric shift.

Is the SRS20150H pin-compatible with other parts in the SRS20xxH series?

Yes-the entire SRS2020H through SRS20150H series shares identical TO-263AB (D2PAK) package dimensions, pinout, and terminal configuration. All variants use the same 3-pin layout with anode, cathode, and exposed cathode tab. This enables design reuse across voltage grades without PCB revision, provided thermal and electrical margins are validated for each specific V_RRM and I_F combination in the SRS20150H application.

Does the SRS20150H meet automotive qualification standards?

Yes-the SRS20150H is explicitly qualified to AEC-Q101 for stress testing including HTGB, HTRB, and temperature cycling. This certification is documented in the product brief and supported by Taiwan Semiconductor's qualification report version A2103. The SRS20150H is approved for use in automotive powertrain, body electronics, and lighting systems where robustness against vibration, thermal shock, and long service life are required.

What is the forward voltage specification for the SRS20150H at 20 A?

The SRS20150H forward voltage is specified at 10 A (1.02 V typical), not 20 A, per the electrical specifications table. At 20 A and 25°C, typical V_F extrapolates to ≈1.15 V based on the published forward characteristics curve (Fig.4). Designers should reference the derating curve (Fig.1) and thermal resistance (1.5 °C/W) to calculate actual V_F under real operating conditions for the SRS20150H.

How is moisture sensitivity managed for the SRS20150H during PCB assembly?

The SRS20150H is rated at Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/85% RH without baking prior to reflow. No floor life limitation applies, and standard lead-free reflow profiles (peak 260°C) can be used without preconditioning. This simplifies SMT line integration and eliminates yield risk from moisture-induced popcorning-critical for high-volume automotive manufacturing of boards using the SRS20150H.
