BZD17C100P MQG Equivalent & Substitute Parts

Part Overview

The BZD17C100P MQG is an active-status zener diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V nominal zener voltage with 800 mW maximum power dissipation. This component is designed for surface mount applications in the Sub SMA package configuration (DO-219AB). The part is ROHS3 compliant and carries unlimited moisture sensitivity level classification, making it suitable for standard industrial and commercial electronic applications.

Substitute parts become necessary when the primary manufacturer part experiences supply constraints, extended lead times, or when design requirements permit cross-platform compatibility with functionally equivalent alternatives from other manufacturers while maintaining identical electrical and mechanical specifications.

• Maximum power dissipation: 800 mW
• Maximum impedance: 200 Ohms
• Reverse leakage current: 1 µA @ 75 V
• Forward voltage: 1.2 V maximum @ 200 mA

Mechanical & Environmental Specifications:

• Package type: DO-219AB (Sub SMA / SMF)
• Mounting configuration: Surface Mount
• Compliance: ROHS3 Compliant
• Moisture sensitivity: Level 1 (Unlimited)

The substitute parts BZD27C100P-E3-08 and BZD27C100P-HE3-08, both manufactured by Vishay General Semiconductor - Diodes Division, meet all electrical and mechanical requirements for direct substitution. Both parts are manufactured in the identical DO-219AB package, maintain equivalent electrical performance across all specified parameters, and carry identical compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts satisfy the electrical and mechanical requirements for direct replacement of the BZD17C100P MQG in standard applications. All three parts maintain active product status and carry ROHS3 compliance certification.

BZD27C100P-E3-08 is suitable for general-purpose industrial and commercial applications where automotive qualification is not required. This part provides equivalent electrical performance and identical package configuration.

BZD27C100P-HE3-08 carries AEC-Q101 automotive qualification and is specified for automotive-grade applications. This part is appropriate for designs requiring automotive-level reliability and traceability. The extended lower operating temperature limit (-65°C versus -55°C) provides additional thermal margin in cold-environment applications.

Both Vishay parts are available in higher inventory quantities compared to the Taiwan Semiconductor Corporation source, which may provide supply chain advantages for procurement planning.

Frequently Asked Questions (FAQ)

Q: Can BZD27C100P-E3-08 and BZD27C100P-HE3-08 be used interchangeably with BZD17C100P MQG?

A: Both Vishay parts are electrically and mechanically equivalent to the BZD17C100P MQG across all specified parameters. They share identical zener voltage (100 V), power rating (800 mW), impedance (200 Ohms), and package configuration (DO-219AB). Direct substitution is supported for applications where automotive qualification is not mandated.

Q: What is the difference between BZD27C100P-E3-08 and BZD27C100P-HE3-08?

A: Both parts are electrically identical. The primary distinction is that BZD27C100P-HE3-08 carries AEC-Q101 automotive qualification and is designated for automotive-grade applications. The BZD27C100P-HE3-08 also specifies a lower operating temperature minimum of -65°C compared to the standard -55°C range.

Q: Are there tolerance differences between the main part and substitutes?

A: The BZD17C100P MQG specifies ±6% zener voltage tolerance. The substitute parts do not list tolerance specifications in the provided data. Tolerance verification against design requirements is necessary if this parameter is critical to circuit performance.

Q: Do all three parts use the same package footprint?

A: Yes. All three parts use the DO-219AB package configuration, which is designated as Sub SMA or SMF depending on supplier nomenclature. PCB footprints and land patterns are identical across all three parts.

Q: What are the compliance and certification statuses?

A: All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (Unlimited) for all parts. The BZD27C100P-HE3-08 additionally carries AEC-Q101 automotive qualification.
