Diodes Incorporated G10H150CTW

Overview

G10H150CTW from Littelfuse Semiconductor is a trench Schottky rectifier optimized for high-efficiency power supply applications, featuring 150 V reverse voltage rating, 10 A average forward current at Tc = 140°C, and ultra-low forward voltage (0.79 V typ. @ 5 A, 25°C). It operates reliably from –55°C to +175°C and is AEC-Q101 Rev_D qualified for automotive-grade reliability.

For engineers reviewing the G10H150CTW datasheet, G10H150CTW pinout, G10H150CTW application, or G10H150CTW equivalent, key selection criteria include its soft fast switching behavior, thermal resistance (RthJC = 5°C/W), junction capacitance (540 pF), and TO-220AB package compatibility with standard heatsinks.

Technical Context

This device uses a trench Schottky architecture to minimize forward voltage drop while maintaining low leakage and fast recovery-critical for high-frequency DC/DC converters and synchronous rectification stages. Its soft reverse recovery reduces EMI and enables efficient operation in compact, thermally constrained power supplies.

The device is rated for 180 A non-repetitive surge current (8.3 ms half-sine) and exhibits stable reverse leakage (<10 mA @ 125°C, 150 V), supporting robust performance in automotive engine control units and industrial SMPS where thermal cycling and transient immunity are essential.

FAQ

Is G10H150CTW pin-compatible with standard TO-220AB dual-diode packages?

Yes. G10H150CTW uses the industry-standard TO-220AB outline with Pin 1 = Anode, Pin 2 = Cathode, and Pin 3 = Case/TAB tied internally to Pin 1. Its mechanical dimensions (A: 14.4–15.2 mm, B: 9.65–10.67 mm) match JEDEC TO-220AB specifications, enabling drop-in replacement in existing layouts.

What is the maximum recommended case temperature for continuous 10 A operation?

The datasheet specifies IAV = 10 A at Tc = 140°C. Operation above this temperature requires linear derating per Figure 1; at 150°C case, maximum sustainable average current drops to ~8.5 A. Exceeding 140°C continuously risks accelerated parametric drift and reduced lifetime.

Does G10H150CTW require a thermal pad or insulator when mounted to a heatsink?

Yes-if the heatsink is grounded or referenced to a different potential than the anode, electrical isolation is mandatory. The metal tab (Pin 3) is internally connected to Pin 1 (Anode), so a mica or ceramic insulator plus thermal grease is required to prevent short circuits while maintaining thermal performance (RthJC = 5°C/W assumes proper mounting).

Can G10H150CTW replace a standard silicon PN rectifier in an existing design?

Yes, with verification of reverse voltage margin and layout thermal capacity. Its 150 V VRRM matches common 100–150 V silicon diodes, and its lower VF reduces conduction loss-but note its higher IR at elevated temperature and lack of avalanche rating, so transient clamping capability must be confirmed separately.
