Taiwan Semiconductor Corporation SR010HB0G

Overview

SR010HB0G from Taiwan Semiconductor is a 100 V, 0.5 A AEC-Q101-qualified Schottky barrier rectifier in DO-204AL (DO-41) package, featuring 0.85 V forward voltage at 0.5 A and 100 µA reverse leakage at 25°C, used in automotive-grade DC-DC converters and SMPS secondary-side rectification.

For engineers reviewing the SR010HB0G datasheet, SR010HB0G pinout, SR010HB0G application, or SR010HB0G equivalent, key selection criteria include peak reverse voltage (100 V), surge current rating (30 A), junction temperature range (–55°C to +150°C), thermal resistance (50°C/W), and AEC-Q101 qualification status.

Technical Context

This discrete Schottky diode uses a single-die construction with guard ring structure for overvoltage protection and pure tin-plated leads compliant with J-STD-002 solderability. Its low VF and high IFSM support high-efficiency, compact power conversion in space-constrained automotive and industrial designs.

Thermal performance is defined by R_θJA = 50°C/W and maximum junction temperature of +150°C, enabling operation under sustained load in ambient temperatures up to +85°C when mounted on standard FR-4 PCB with minimal copper area.

FAQ

What is the maximum junction temperature rating for SR010HB0G?

The SR010HB0G has a maximum junction temperature (T_J) of +150°C, validated per AEC-Q101 stress testing. This allows operation in under-hood automotive environments where ambient temperatures reach +85°C, provided thermal design maintains junction temperature below this limit. The SR010HB0G's R_θJA of 50°C/W defines the thermal path from junction to ambient under standard PCB conditions.

Is SR010HB0G pin-compatible with other devices in the SR002–SR010 family?

Yes, all SR002–SR010 devices share identical DO-204AL (DO-41) packaging, anode/cathode pinout, and mechanical dimensions. The SR010HB0G differs only in V_RRM (100 V) and electrical parameters such as V_F and I_R; no PCB layout change is needed when substituting within this family for voltage-scaling purposes.

Does SR010HB0G meet automotive qualification standards?

Yes, the "H" suffix in SR010HB0G explicitly denotes AEC-Q101 qualification. This includes HTOL, temperature cycling, HAST, and mechanical shock testing per the AEC-Q101-Rev E standard. The SR010HB0G is approved for use in automotive powertrain, body electronics, and ADAS subsystems where reliability under harsh conditions is mandatory.

What is the reverse leakage current specification for SR010HB0G at elevated temperature?

At 100 V reverse bias and T_J = 125°C, the SR010HB0G exhibits ≤2 mA reverse leakage current. At 25°C, it is rated ≤100 µA. This temperature-dependent behavior is critical for maintaining regulation stability in high-temperature power supplies; the SR010HB0G's leakage remains well within typical design margins up to its 150°C T_J limit.

How does the guard ring feature improve reliability of SR010HB0G?

The guard ring in SR010HB0G mitigates edge breakdown under transient overvoltage conditions by redistributing electric field stress away from the active junction periphery. This structural enhancement increases the device's ruggedness against line transients and ESD events without requiring external snubbers-directly improving long-term reliability in unregulated input stages where the SR010HB0G is commonly deployed.
