Product details
Overview
G30H100CTW from Diodes Incorporated is a Trench Schottky rectifier optimized for high-frequency power conversion, featuring 100 V reverse voltage rating, 30 A average forward current at 150°C case temperature, and low 0.63 V typical forward voltage at 15 A/25°C - deployed in on-board DC-DC converters and high-frequency inverters where switching loss minimization is critical.
For engineers reviewing the G30H100CTW datasheet, G30H100CTW pinout, G30H100CTW application, or G30H100CTW equivalent, key selection criteria include junction temperature capability up to +175°C, AEC-Q101 Rev_D qualification for automotive-grade reliability, thermal resistance of 1°C/W (junction-to-case), and negligible reverse recovery charge for efficient SMPS operation.
Technical Context
This device employs trench-based Schottky architecture to achieve superior trade-off between forward voltage drop and leakage current - with 0.63 V VF at 15 A/25°C and only 1.2 µA IR at 100 V/25°C. Its 1040 pF junction capacitance at 4 V reverse bias supports stable high-frequency operation up to several MHz.
Designed for surface-mount-compatible TO-220AB packaging with isolated tab, it delivers 280 A non-repetitive surge current handling and operates across -55°C to +175°C junction temperature range - enabling use in thermally constrained automotive and industrial power stages without active cooling.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB3100-E3/57T (Vishay) | 30 A/100 V, VF = 0.75 V @ 15 A/25°C, RthJC = 1.5°C/W, no AEC-Q101 rating | Limited to commercial-grade industrial supplies; not validated for automotive thermal cycling | Select when AEC-Q101 is unnecessary and 0.12 V higher VF is acceptable for cost-driven BOMs |
| SS310H (ON Semiconductor) | 30 A/100 V, VF = 0.65 V @ 15 A/25°C, RthJC = 1.2°C/W, AEC-Q101 qualified but no 175°C TJ rating | Suitable for automotive cabin electronics but not under-hood due to 150°C max TJ | Prefer for dashboard modules where full 175°C margin is not required and footprint compatibility is critical |
Compared with SB3100-E3/57T and SS310H, G30H100CTW uniquely combines 175°C junction rating, 1°C/W thermal resistance, and AEC-Q101 Rev_D validation - making it the only option qualified for high-temperature automotive power stages requiring long-term reliability without derating.

FAQ
Is G30H100CTW pin-compatible with standard TO-220AB Schottky rectifiers?
Yes - G30H100CTW uses JEDEC-standard TO-220AB mechanical dimensions and pinout (Anode–Cathode–Anode), with Pin 2 as isolated cathode/tab. It mounts identically to industry-standard 3-pin TO-220AB rectifiers and requires no PCB redesign when replacing compatible devices.
What is the maximum allowable case temperature for continuous 30 A operation?
The datasheet specifies 30 A average forward current at Tc = 150°C. Operation above this temperature requires derating per Figure 1 - at 160°C case temperature, maximum continuous current drops to ~26 A, and at 175°C, it falls to ~20 A. Thermal interface quality directly impacts achievable current.
Does G30H100CTW support bidirectional current flow in reverse-conducting applications?
No - G30H100CTW is a unidirectional Schottky rectifier. Its structure allows forward conduction only from anode to cathode (Pin 1/Pin 3 → Pin 2). Reverse conduction is blocked up to 100 V, and attempting reverse current flow risks permanent damage due to lack of reverse voltage capability.
How does the 1040 pF junction capacitance affect EMI performance in 100 kHz switch-mode designs?
At 100 kHz, the 1040 pF junction capacitance presents ~1.5 kΩ impedance, minimizing displacement current injection into control loops. This value is stable across reverse bias (see Fig.4), enabling predictable snubber design and reducing common-mode noise generation compared to higher-CJ alternatives like planar Schottkys.
