GL34B-TP Equivalent & Substitute Parts

Part Overview

The GL34B-TP is a general-purpose rectifier diode rated for 100 V DC reverse voltage and 500 mA average rectified current, manufactured by Micro Commercial Co in a Mini MELF surface mount package. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design requirements and procurement needs. Equivalent parts maintain identical electrical specifications and package compatibility, while substitute parts offer functional alternatives with modified electrical characteristics or package formats suitable for specific application requirements.

Substitute Part Grouping Explanation

Substitution of the GL34B-TP is determined by matching critical electrical parameters: reverse voltage rating (100 V), average rectified current capacity (500 mA), forward voltage drop characteristics, and surface mount package compatibility. The GL34B-TP operates with standard recovery speed (>500 ns) and reverse leakage of 5 µA at 100 V.

Substitute parts are grouped into two categories:

Category 1: Direct Electrical Equivalents with Package Variation Parts GL34B-E3/98, BYM07-100-E3/83, BYM07-100-E3/98, EGL34B-E3/98, and RGL34B-E3/98 maintain the 100 V / 500 mA electrical specification. These parts transition from the obsolete Mini MELF package to the active DO-213AA (Glass) package format, both surface mount technologies. All Category 1 substitutes are manufactured by Vishay General Semiconductor and carry active product status with ROHS3 compliance.

Category 2: Functional Substitute with Reduced Current Rating Part BAV101-GS18 provides a 100 V rated diode with reduced current capacity (250 mA versus 500 mA) in the SOD-80 Mini MELF package. This part features fast recovery characteristics (≤500 ns) and automotive qualification (AEC-Q101). BAV101-GS18 is suitable for applications where the 500 mA current requirement can be reduced or where automotive-grade reliability is required.

Engineering Selection Recommendations

For Direct Replacement (100 V / 500 mA Requirement):

GL34B-E3/98 is the primary active equivalent, maintaining identical electrical specifications (100 V, 500 mA, 1.2 V forward drop) with standard recovery characteristics. This part transitions from Mini MELF to DO-213AA package format and carries active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). GL34B-E3/98 is available in Tape & Reel packaging with 79,004 units in stock.

Frequently Asked Questions (FAQ)

Q: Can GL34B-E3/98 directly replace GL34B-TP in existing designs?

A: GL34B-E3/98 maintains identical electrical specifications (100 V, 500 mA, 1.2 V forward drop) and standard recovery characteristics. The primary difference is package format transition from Mini MELF to DO-213AA (Glass). Both are surface mount technologies with compatible footprints for most applications. Verification of PCB layout compatibility with DO-213AA dimensions is required.

Q: What is the difference between standard recovery and fast recovery variants?

A: GL34B-TP and GL34B-E3/98 operate with standard recovery speed (>500 ns). BYM07-100-E3/83, BYM07-100-E3/98, EGL34B-E3/98, and BAV101-GS18 feature fast recovery (≤500 ns). Fast recovery reduces reverse recovery time, lowering switching losses in high-frequency applications. Standard recovery is suitable for low-frequency rectification circuits.

Q: Is BAV101-GS18 suitable as a substitute for GL34B-TP?

A: BAV101-GS18 is a functional substitute only for applications where 250 mA average rectified current is acceptable.
