BZD27C100P MTG Equivalent & Substitute Parts

Part Overview

The BZD27C100P MTG is an active-status Zener diode rated for 100 V nominal voltage and 1 W maximum power dissipation in a Surface Mount Sub SMA package (DO-219AB). This component is manufactured by Taiwan Semiconductor Corporation and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when design requirements permit tolerance variations, power rating adjustments, or alternative packaging configurations while maintaining core electrical performance in 100 V Zener applications. Equivalent parts from alternative manufacturers may be necessary due to inventory availability, supply chain considerations, or specific qualification requirements such as automotive-grade certifications.

Substitute Part Grouping Explanation

Substitute parts for the BZD27C100P MTG are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical core electrical specifications: 100 V nominal Zener voltage, 200 Ohms maximum impedance, 1 µA reverse leakage at 75 V, 1.2 V forward voltage at 200 mA, and DO-219AB package configuration. These parts differ only in tolerance specification (±5% versus ±6%) and packaging format (Tape & Reel). Parametric equivalents include BZD27C100P R3G and BZD27C100P RVG, both manufactured by Taiwan Semiconductor Corporation.

Similar Parts maintain the 100 V nominal Zener voltage, 200 Ohms maximum impedance, and DO-219AB package but feature reduced maximum power rating (800 mW versus 1 W) and are manufactured by Vishay General Semiconductor - Diodes Division. These include BZD27C100P-E3-08 and BZD27C100P-HE3-08. The BZD27C100P-HE3-08 carries automotive-grade qualification (AEC-Q101) and extended operating temperature range (-65°C to 175°C).

Substitution is valid when circuit design permits the specified parameter variations without functional degradation.

Engineering Selection Recommendations

BZD27C100P R3G and BZD27C100P RVG are direct parametric equivalents suitable for applications where the main part is unavailable. Both maintain 1 W power rating and identical electrical characteristics. The ±5% tolerance specification provides tighter voltage regulation compared to the ±6% tolerance of the main part. Both parts are ROHS3 compliant and carry active product status from Taiwan Semiconductor Corporation. Selection between these two equivalents depends on packaging format requirements: both are supplied in Tape & Reel configuration.

BZD27C100P-E3-08 and BZD27C100P-HE3-08 are suitable substitutes for applications where 800 mW power dissipation is sufficient. Both parts maintain the 100 V nominal voltage, 200 Ohms impedance, and identical leakage/forward voltage characteristics. The BZD27C100P-HE3-08 includes automotive-grade qualification (AEC-Q101) and extended low-temperature operating range (-65°C versus -55°C), making it appropriate for automotive and extended-temperature applications. Both Vishay parts are ROHS3 compliant with active product status.

Selection of substitute parts must confirm that circuit power dissipation requirements do not exceed the specified maximum power rating of the selected component.

Frequently Asked Questions (FAQ)

Q: Can BZD27C100P R3G or BZD27C100P RVG be used as direct replacements for BZD27C100P MTG?

A: Yes. Both parts maintain identical 100 V nominal voltage, 1 W power rating, 200 Ohms impedance, and DO-219AB package configuration. The ±5% tolerance of these equivalents is tighter than the ±6% tolerance of the main part, providing improved voltage regulation. Both are ROHS3 compliant and active-status products from Taiwan Semiconductor Corporation.

Q: What is the primary difference between the Taiwan Semiconductor and Vishay substitute options?

A: Taiwan Semiconductor equivalents (BZD27C100P R3G, BZD27C100P RVG) maintain the full 1 W power rating. Vishay parts (BZD27C100P-E3-08, BZD27C100P-HE3-08) are rated for 800 mW maximum power. The BZD27C100P-HE3-08 includes automotive-grade qualification (AEC-Q101) and extended operating temperature range (-65°C to 175°C).

Q: Can I use BZD27C100P-E3-08 or BZD27C100P-HE3-08 if my circuit requires 1 W power dissipation?

A: No. These Vishay parts are rated for 800 mW maximum power. Use only if circuit design confirms power dissipation does not exceed 800 mW. Exceeding this rating will degrade component reliability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (BZD27C100P R3G, BZD27C100P RVG, BZD27C100P-E3-08, BZD27C100P-HE3-08) are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity).

Q: Which substitute part is suitable for automotive applications?

A: BZD27C100P-HE3-08 carries AEC-Q101 automotive-grade qualification and extended operating temperature range (-65°C to 175°C). This part is appropriate for automotive circuit designs. Other substitutes do not carry automotive qualification.

Q: Do all substitute parts use the same DO-219AB package?

A: Yes. All substitute parts use the DO-219AB (Sub SMA / SMF) surface mount package, ensuring mechanical and thermal compatibility with the main part.

Q: What is the difference between Tape & Reel and other packaging formats?

A: Tape & Reel (TR) packaging is standard for automated assembly processes. The main part BZD27C100P MTG does not specify packaging format, while all listed substitutes are supplied in Tape & Reel configuration. This difference does not affect electrical performance or mechanical compatibility.
