BZD27C100P MQG Equivalent & Substitute Parts

Part Overview

The BZD27C100P MQG is an active-status zener diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V nominal zener voltage and 1 W maximum power dissipation in a surface mount Sub SMA package (DO-219AB). This component is designed for voltage regulation and protection applications requiring stable reverse-bias operation across industrial temperature ranges. Substitute parts are identified to address inventory availability, packaging format preferences, and tolerance specifications while maintaining functional equivalence within the specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitute parts for the BZD27C100P MQG are classified into two categories based on parametric alignment:

Parametric Equivalents maintain identical electrical specifications across all critical parameters: 100 V nominal zener voltage, 200 Ohms maximum impedance, 1 µA reverse leakage current at 75 V, 1.2 V maximum forward voltage at 200 mA, and -55°C to 175°C operating temperature range. 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 share the same nominal zener voltage (100 V), impedance (200 Ohms), reverse leakage current (1 µA @ 75 V), forward voltage (1.2 V @ 200 mA), and package type (DO-219AB), but differ in maximum power rating (800 mW versus 1 W) and operating temperature range (-65°C to 175°C versus -55°C to 175°C). Similar parts include BZD27C100P-E3-08 and BZD27C100P-HE3-08, both manufactured by Vishay General Semiconductor - Diodes Division. The BZD27C100P-HE3-08 carries automotive-grade qualification (AEC-Q101).

Substitution eligibility is determined by matching the following critical parameters: nominal zener voltage, impedance, reverse leakage current, forward voltage, and package type. Power rating and operating temperature range must be evaluated against application requirements.

Engineering Selection Recommendations

BZD27C100P R3G and BZD27C100P RVG are direct parametric equivalents to the BZD27C100P MQG. Both parts are manufactured by Taiwan Semiconductor Corporation, maintain active product status, and comply with ROHS3 and REACH requirements. These substitutes feature improved tolerance specification (±5% versus ±6%) and are available in Tape & Reel packaging format. Selection between these two parametric equivalents is determined by inventory availability and packaging requirements.

BZD27C100P-E3-08 and BZD27C100P-HE3-08 are similar parts manufactured by Vishay General Semiconductor - Diodes Division. Both maintain the same nominal zener voltage, impedance, reverse leakage current, forward voltage, and DO-219AB package type. These parts operate across an extended lower temperature range (-65°C versus -55°C minimum) and are rated for 800 mW maximum power dissipation. The BZD27C100P-HE3-08 carries automotive-grade qualification (AEC-Q101) and is suitable for applications requiring automotive-level reliability. Selection of similar parts is appropriate when the reduced power rating (800 mW) and extended low-temperature capability align with application requirements.

All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and active product status, ensuring long-term availability and regulatory conformance.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are parametric equivalents with identical electrical specifications across all critical parameters: 100 V nominal zener voltage, 200 Ohms impedance, 1 µA reverse leakage current, 1.2 V forward voltage, and -55°C to 175°C operating temperature. The tolerance specification is improved (±5% versus ±6%). Packaging format differs (Tape & Reel versus bulk), but the component itself is functionally equivalent.

Q: What is the difference between parametric equivalents and similar parts?

A: Parametric equivalents (BZD27C100P R3G, BZD27C100P RVG) match all electrical specifications and operating temperature range of the main part. Similar parts (BZD27C100P-E3-08, BZD27C100P-HE3-08) share the same nominal zener voltage, impedance, and leakage characteristics but differ in maximum power rating (800 mW versus 1 W) and minimum operating temperature (-65°C versus -55°C). Similar parts require application-level verification that the reduced power rating and extended temperature range are acceptable.

Q: Are the Vishay parts (BZD27C100P-E3-08, BZD27C100P-HE3-08) suitable for my application if it requires 1 W power dissipation?

A: No. These parts are rated for 800 mW maximum power dissipation. If your application requires sustained 1 W operation, the BZD27C100P MQG or its parametric equivalents (BZD27C100P R3G, BZD27C100P RVG) must be used.

Q: What is the significance of the AEC-Q101 qualification on BZD27C100P-HE3-08?

A: AEC-Q101 is an automotive-grade qualification standard. The BZD27C100P-HE3-08 meets automotive reliability and quality requirements. This part is suitable for automotive applications requiring qualified components. Non-automotive applications do not require this qualification.

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

Q: What is the difference between the packaging formats listed (bulk versus Tape & Reel)?

A: Packaging format affects handling and assembly processes. The main part (BZD27C100P MQG) is supplied in bulk format. Parametric equivalents (BZD27C100P R3G, BZD27C100P RVG) and similar parts (BZD27C100P-E3-08, BZD27C100P-HE3-08) are supplied in Tape & Reel format, which is standard for automated assembly. The component specifications and performance are identical; only the delivery and handling method differs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts, including the main part and all substitutes, are ROHS3 compliant and REACH unaffected. Moisture Sensitivity Level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements.
