MBR20150CT-G1 Equivalent & Substitute Parts

Part Overview

The MBR20150CT-G1 is a Schottky diode array in a 1 Pair Common Cathode configuration rated for 150 V DC reverse voltage and 10 A average rectified current per diode. Manufactured by Diodes Incorporated, this through-hole TO-220-3 package component is classified as obsolete. Due to its obsolete product status, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure ongoing component availability for new production and field replacements.

Substitute Part Grouping Explanation

Substitution of the MBR20150CT-G1 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

Diode Configuration: 1 Pair Common Cathode
Technology: Schottky
Voltage - DC Reverse (Vr) (Max): 150 V
Current - Average Rectified (Io) (per Diode): 10 A
Mounting Type: Through Hole
Package / Case: TO-220-3

Secondary Compatibility Parameters:

Voltage - Forward (Vf) (Max) @ If: Acceptable range 790 mV to 1.2 V @ 10 A
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Operating Temperature - Junction: Minimum -55°C, maximum 150°C or higher
Current - Reverse Leakage @ Vr: Acceptable range 5 µA to 500 µA @ 150 V

A: No. The DSA10C150PB has a reduced current rating of 5 A per diode compared to the required 10 A specification. Use only in applications with maximum 5 A current requirements.

Q: What is the primary difference between MBR20150SCT-G1 and the obsolete MBR20150CT-G1?

A: The MBR20150SCT-G1 is the active equivalent with identical electrical specifications. The primary differences are active product status, extended operating temperature range to 175°C (versus 150°C), automotive grade qualification (AEC-Q101), and tube packaging format.

Q: Are all substitute parts compatible with TO-220-3 mounting?

A: Yes. All listed substitute parts use TO-220-3 package configuration and are compatible with through-hole mounting on standard PCB layouts designed for TO-220-3 components.

Q: Which substitute has the lowest forward voltage drop?

A: DSSK20-015A has the lowest forward voltage at 790 mV @ 10 A, compared to 900 mV for the main part. This results in reduced power dissipation in applications with continuous 10 A current.

Q: Which substitute has the best reverse leakage characteristics?

A: MBR20150CT (Diotec Semiconductor) has the lowest reverse leakage at 5 µA @ 150 V, compared to 50 µA for the main part. This provides superior blocking characteristics in reverse bias conditions.

Q: Can I use MBR20150CT (Diotec) in applications requiring -55°C minimum operating temperature?

A: The MBR20150CT (Diotec) has a minimum operating temperature of -50°C, which is 5°C higher than the -55°C requirement. Verify application temperature requirements before selection.

Q: Which substitute offers the highest inventory availability?

A: MBR20150CT (Diotec Semiconductor) has the highest inventory at 55248 units in stock, followed by MBR10150CT (Taiwan Semiconductor Corporation) at 27000 units.

Q: Are automotive-grade substitutes available?

A: Yes. MBR20150SCT-G1 (Diodes Incorporated) and MBR10150CTHC0G (Taiwan Semiconductor Corporation) both carry automotive grade designation with AEC-Q101 qualification.

Q: What is the difference between TO-220-3 and TO-220AB package designations?

A: Both designations refer to the same physical TO-220-3 package form factor. TO-220AB is an alternative supplier designation for the same package. All listed parts are mechanically compatible.

Q: Can I substitute based on forward voltage alone?

A: No. Forward voltage is one parameter among several critical specifications. All primary criteria (voltage rating, current rating, configuration, package, and mounting type) must be met for valid substitution.
