Product details
Overview
G40H100CTW from Diodes Incorporated is a trench Schottky rectifier rated for 100 V reverse voltage and 40 A average forward current at Tc = 125°C, featuring 0.64 V forward voltage at 20 A/25°C, 1360 pF junction capacitance, and AEC-Q101 qualified construction for automotive-grade reliability in high-frequency DC-DC converters.
For engineers reviewing the G40H100CTW datasheet, G40H100CTW pinout, G40H100CTW application, or G40H100CTW equivalent, this device serves as a low-loss, high-temperature rectifier where fast switching, minimal conduction loss, and thermal robustness are critical in compact power supplies and on-board inverters.
Technical Context
This Schottky diode uses trench MOS structure to achieve lower forward voltage versus conventional planar Schottky devices while maintaining acceptable leakage at elevated temperatures. Its 100 V VRRM rating supports 48 V and 60 V bus systems with margin, and its 250 A IFSM rating enables robust surge handling in transient-prone environments.
The device's RthJC of 2 °C/W (junction-to-case) and RthJL of 1 °C/W (junction-to-lead) reflect optimized thermal path design for TO-220AB mounting on copper heatsinks. Junction capacitance of 1360 pF at 4 V reverse bias supports operation up to ~1 MHz in high-frequency switching topologies.
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 |
|---|---|---|---|
| Vishay VS-40CPH01-M3 | Same 100 V/40 A rating but planar Schottky; VF = 0.72 V @ 20A/25°C; IR = 15 mA @ 100V/125°C | Higher conduction loss and leakage; less suitable for thermally constrained automotive modules | Select when cost sensitivity outweighs 80 mV VF advantage and 5 mA IR reduction |
| ON Semiconductor MBR40100CT | 100 V/40 A dual common-cathode; VF = 0.75 V @ 20A/25°C; no AEC-Q101 qualification | Lacks automotive qualification and has higher VF; limited to industrial/commercial use only | Select for non-automotive 48 V telecom or server PSUs where qualification is not required |
Compared with VS-40CPH01-M3 and MBR40100CT, G40H100CTW delivers lower forward drop, tighter leakage control at high temperature, and automotive-grade reliability-making it optimal for space-constrained, thermally aggressive applications requiring long-term stability.

FAQ
What is the maximum allowable case temperature for continuous operation?
The G40H100CTW supports continuous operation up to 120°C case temperature per its IAV derating curve, delivering full 40 A average forward current. At 125°C case, current must be reduced to ~37 A; operation beyond 150°C case requires active derating per Figure 1 in DS44954 Rev. 3–2.
Is the TO-220AB package electrically insulated?
No-the TO-220AB package used in G40H100CTW has the cathode (Pin 2) electrically connected to the metal tab. Electrical isolation requires a mica or polymer insulator washer and isolated mounting hardware when the heatsink is grounded or at a different potential.
Does this part support synchronous rectification drive?
No-G40H100CTW is a passive Schottky rectifier and does not integrate gate drive circuitry or logic interfaces. It functions as a unidirectional, self-commutating device; synchronous rectification requires external MOSFETs and controller timing signals.
How is polarity marked on the device body?
Polarity is marked on the body with a cathode band adjacent to Pin 2 (cathode/tab). The marking code "G40H100CTW" appears beside the band, and Pin 1 and Pin 3 are both anodes-confirmed by the internal dual-die common-cathode configuration shown in the mechanical drawing.
