GL34D-TP Equivalent & Substitute Parts

Part Overview

The GL34D-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 200 V DC reverse voltage and 500 mA average rectified current in a Surface Mount Mini MELF package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

The GL34D-TP operates across a junction temperature range of -65°C to 175°C and is RoHS3 compliant. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating available packaging options.

Engineering Selection Recommendations

Primary Substitutes (Full Electrical Equivalence):

GL34D-E3/98, BYM07-200-E3/98, BYM07-200/32, EGL34D-E3/98, RGL34D-E3/98, and RGL34DHE3/98 are all active products from Vishay General Semiconductor that maintain the 500 mA current rating and 200 V voltage specification. All are RoHS3 compliant with MSL 1 rating.

GL34D-E3/98 provides the closest electrical match with identical forward voltage specification (1.2 V @ 500 mA) and standard recovery speed characteristics. This part is recommended as the primary substitute when package compatibility with DO-213AA is acceptable.

BYM07-200-E3/98, BYM07-200/32, EGL34D-E3/98, RGL34D-E3/98, and RGL34DHE3/98 offer enhanced performance with fast recovery characteristics (≤500ns) compared to the standard recovery specification of the GL34D-TP. These parts are suitable for applications where improved switching performance is beneficial. Forward voltage specifications range from 1.25 V to 1.3 V @ 500 mA, which remains within typical application tolerances.

Secondary Substitute (Reduced Current Rating):

BAV103-GS08 is an active product suitable for applications where the full 500 mA capacity is not required. This part maintains the 200 V voltage rating but is rated for 250 mA average rectified current. BAV103-GS08 offers superior reverse leakage characteristics (100 nA @ 200 V) and fast recovery performance. This part is AEC-Q101 qualified for automotive applications and maintains package compatibility with the original DO-213AC MINI-MELF format.

All substitute parts are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, matching the compliance profile of the GL34D-TP.

Frequently Asked Questions (FAQ)

Q: Can GL34D-E3/98 directly replace GL34D-TP in all applications?

A: GL34D-E3/98 maintains identical electrical specifications for voltage (200 V), current (500 mA), and forward voltage (1.2 V @ 500 mA). The primary difference is packaging format: GL34D-E3/98 uses DO-213AA (Glass) while GL34D-TP uses DO-213AC MINI-MELF. Both are surface mount packages with compatible footprints for most applications. Verify PCB layout compatibility before substitution.

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

A: GL34D-TP specifies standard recovery with >500ns recovery time at >200mA. Substitute parts BYM07-200-E3/98, BYM07-200/32, EGL34D-E3/98, RGL34D-E3/98, and RGL34DHE3/98 feature fast recovery with ≤500ns recovery time. Fast recovery diodes switch more quickly, reducing switching losses and heat generation. This enhancement is compatible with GL34D-TP applications and often improves circuit performance.

Q: Is BAV103-GS08 suitable as a substitute for GL34D-TP?

A: BAV103-GS08 is suitable only for applications where the average rectified current requirement does not exceed 250 mA. This part maintains the 200 V voltage rating and offers superior reverse leakage performance (100 nA vs. 5 µA). BAV103-GS08 retains package compatibility with the original DO-213AC MINI-MELF format and includes AEC-Q101 automotive qualification. Do not use this part in circuits requiring the full 500 mA capacity.

Q: What are the packaging differences among substitute parts?

A: GL34D-E3/98, BYM07-200-E3/98, BYM07-200/32, EGL34D-E3/98, RGL34D-E3/98, and RGL34DHE3/98 use DO-213AA (Glass) packaging. BAV103-GS08 uses DO-213AC MINI-MELF, which matches the original GL34D-TP package format. DO-213AA and DO-213AC are both surface mount packages with similar footprints. Verify PCB design files to confirm pad compatibility before component selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (GL34D-E3/98, BYM07-200-E3/98, BYM07-200/32, EGL34D-E3/98, RGL34D-E3/98, RGL34DHE3/98, and BAV103-GS08) are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, matching the compliance profile of the obsolete GL34D-TP.

Q: Which substitute offers the best availability?

A: RGL34DHE3/98 has the highest inventory level at 24,980 pieces. EGL34D-E3/98 offers 11,539 pieces, and RGL34D-E3/98 provides 10,400 pieces. BAV103-GS08 has the largest stock at 746,300 pieces but is rated for 250 mA rather than 500 mA. For 500 mA applications, RGL34DHE3/98 is recommended based on availability.

Q: What is the temperature operating range for substitute parts?

A: GL34D-E3/98, BYM07-200-E3/98, BYM07-200/32, EGL34D-E3/98, RGL34D-E3/98, and RGL34DHE3/98 all operate across -65°C to 175°C junction temperature, matching the GL34D-TP specification. BAV103-GS08 specifies a maximum junction temperature of 175°C with a minimum of -65°C implied by standard automotive qualification (AEC-Q101).
