BZD27C20P RVG Equivalent & Substitute Parts

Part Overview

The BZD27C20P RVG is a Zener diode rated at 20 V nominal voltage with 1 W maximum power dissipation, manufactured by Taiwan Semiconductor Corporation. This surface mount component operates across the temperature range of -55°C to 175°C and is packaged in the DO-219AB (Sub SMA) form factor. The device is ROHS3 compliant and maintains an active product status.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter tolerances while maintaining mechanical compatibility and regulatory compliance. The primary consideration for substitution involves matching the nominal Zener voltage, power rating, impedance characteristics, and package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BZD27C20P RVG is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Nominal Zener voltage of 20 V
• Maximum impedance of 15 Ohms
• Reverse leakage current of 1 µA @ 15 V
• Forward voltage of 1.2 V @ 200 mA

Mechanical Compatibility Criteria:

• Package form factor: DO-219AB (Sub SMA / SMF)
• Surface mount mounting type
• Tape & Reel packaging acceptable for production environments

Regulatory Compliance Criteria:

• ROHS3 compliance
• REACH unaffected status
• Active product status

The substitute parts identified (BZD27C20P-E3-08, BZD27C20P-HE3-08, BZD27C20P-M3-08) all share the same base product number BZD27 and maintain electrical parameter equivalence. These parts are manufactured by Vishay General Semiconductor - Diodes Division and are available in high inventory quantities.

Parameter Comparison

Engineering Selection Recommendations

BZD27C20P-E3-08 (Vishay): This substitute maintains full electrical parameter equivalence with the main part. The extended operating temperature range (-65°C to 175°C) provides additional thermal margin. This part is suitable for general industrial applications and is available in high inventory quantities (26,983 pcs).

BZD27C20P-HE3-08 (Vishay): This variant is qualified to AEC-Q101 automotive standards and carries automotive-grade designation. The electrical parameters remain equivalent to the main part, with the same extended temperature range. This part is appropriate for automotive and mission-critical applications requiring automotive qualification. Inventory availability is 30,645 pcs.

BZD27C20P-M3-08 (Vishay): This substitute is part of the BZD27-M series and maintains electrical equivalence with identical impedance, leakage current, and forward voltage characteristics. The extended operating temperature range matches the other Vishay variants. Inventory availability is 30,625 pcs.

All three substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment with the original part. The primary distinction between substitutes is the automotive qualification of the HE3-08 variant and series designation differences.

Frequently Asked Questions (FAQ)

Q: Can BZD27C20P-E3-08, BZD27C20P-HE3-08, and BZD27C20P-M3-08 be used interchangeably with BZD27C20P RVG?

A: Yes, all three Vishay variants maintain electrical parameter equivalence with the original part. They share identical nominal Zener voltage (20 V), impedance (15 Ohms), reverse leakage current (1 µA @ 15 V), and forward voltage (1.2 V @ 200 mA). All are packaged in DO-219AB form factor and are ROHS3 compliant.

Q: What is the difference in power rating between the main part and the substitutes?

A: The BZD27C20P RVG is rated at 1 W maximum power dissipation, while the Vishay substitutes are rated at 800 mW. Applications requiring the full 1 W dissipation capability should account for this 200 mW reduction in maximum power handling.

Q: Why does the BZD27C20P-HE3-08 have automotive qualification while others do not?

A: The BZD27C20P-HE3-08 carries AEC-Q101 automotive qualification, making it suitable for automotive applications requiring certified components. The other variants are suitable for general industrial and commercial applications.

Q: Are the operating temperature ranges different between the main part and substitutes?

A: The main part operates from -55°C to 175°C, while all three Vishay substitutes operate from -65°C to 175°C. The substitutes provide an additional 10°C of low-temperature margin.

Q: Do all parts use the same package form factor?

A: Yes, all parts use the DO-219AB package form factor (Sub SMA / SMF). They are mechanically compatible and can be used in the same PCB footprint.

Q: What is the significance of the base product number BZD27?

A: The BZD27 base product number indicates the Zener diode family. All parts in this comparison share this base designation, confirming they are part of the same product family with consistent electrical characteristics across the 20 V nominal voltage rating.

Q: Are there any compliance or regulatory differences between the parts?

A: All parts are ROHS3 compliant and REACH unaffected. The primary regulatory distinction is the AEC-Q101 automotive qualification of the BZD27C20P-HE3-08 variant.
