Taiwan Semiconductor Corporation SRS16100H

Overview

SRS16100H from Taiwan Semiconductor is a 16A, 100V Schottky barrier rectifier in TO-263AB (D2PAK) package, designed for high-efficiency DC/DC conversion and reverse battery protection in automotive lighting systems. It features 0.90V forward voltage at 8A/25°C, 150A surge capability, AEC-Q101 qualification, and junction temperature rating up to +150°C.

For engineers reviewing the SRS16100H datasheet, SRS16100H pinout, SRS16100H application, or SRS16100H equivalent, key selection criteria include its 100V repetitive peak reverse voltage, low 100µA reverse leakage at 25°C, thermal resistance of 2°C/W, and suitability for automated SMT placement in high-reliability automotive power circuits.

Technical Context

The SRS16100H implements a dual-die Schottky structure optimized for low conduction loss at high current density, with guard ring protection enabling robust overvoltage tolerance. Its 100V V_RRM rating targets mid-range automotive and industrial DC bus applications where higher blocking voltage is required without sacrificing switching speed.

Thermally, the device delivers R_θJC = 2°C/W into the heatsink via its exposed D2PAK drain tab, supporting continuous 16A operation up to +125°C case temperature (derated above that). Reverse leakage remains tightly controlled at ≤100µA at 25°C and ≤5mA at 125°C, critical for low-power standby integrity.

FAQ

What is the maximum junction temperature rating for the SRS16100H?

The SRS16100H has a maximum junction temperature (T_J) rating of +150°C, verified per AEC-Q101 stress testing. This allows uninterrupted operation in under-hood automotive environments where ambient temperatures exceed 105°C, provided thermal design maintains junction temperature below this limit. The SRS16100H achieves this with R_θJC = 2°C/W and a TO-263AB package optimized for PCB heat spreading.

Is the SRS16100H pin-compatible with other parts in the SRS16xxH series?

Yes, all SRS16xxH devices-including SRS16100H-share identical TO-263AB (D2PAK) mechanical footprint, pinout, and thermal pad layout. This enables single PCB design reuse across voltage grades (20V–100V), simplifying BOM management and allowing late-stage voltage optimization without layout changes. The SRS16100H uses the same Anode 1 / Cathode (Tab) / Anode 2 terminal assignment as SRS1620H through SRS1690H.

Does the SRS16100H meet automotive qualification standards?

Yes, the SRS16100H is fully AEC-Q101 qualified, having passed all required stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (UHAST). This certification confirms its suitability for automotive power electronics such as headlamp drivers and battery protection circuits where field reliability is non-negotiable. The SRS16100H carries version code A2103, indicating full compliance with the latest revision of the standard.

What is the forward voltage specification for the SRS16100H at elevated temperature?

The SRS16100H forward voltage increases with junction temperature: typical V_F is 0.90V at 25°C (I_F = 8A), rising to approximately 0.75V at 125°C due to the negative temperature coefficient of Schottky diodes. This behavior improves thermal stability in parallel configurations and reduces conduction loss at high ambient conditions. Data is confirmed in the "Electrical Specifications" section of the official SRS16100H datasheet (Version A2103).

How does the guard ring feature improve reliability in the SRS16100H?

The guard ring in the SRS16100H prevents premature edge breakdown under high electric field stress, ensuring the full 100V V_RRM rating is achieved across process variation and temperature extremes. This structural enhancement eliminates localized avalanche sites that cause parametric drift or catastrophic failure during sustained reverse bias-particularly valuable in automotive reverse-battery protection where the SRS16100H may experience repeated 100V reverse transients. The guard ring is integral to the die design and validated in AEC-Q101 testing.
