Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BZD17C51P RUG are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Nominal Zener voltage: 51 V
• Maximum power dissipation: 800 mW
• Maximum impedance: 60 Ohms
• Reverse leakage current: 1 µA @ 39 V
• Forward voltage: 1.2 V @ 200 mA
• Package standard: DO-219AB surface mount
• RoHS3 compliance requirement

The substitute parts BZD27C51P-E3-08 and BZD27C51P-HE3-08 maintain identical electrical specifications and package compatibility. Both are manufactured by Vishay General Semiconductor - Diodes Division and satisfy the same regulatory compliance standards. The BZD27C51P-HE3-08 variant includes automotive-grade qualification (AEC-Q101), extending application scope to automotive environments.

Parameter Comparison

Engineering Selection Recommendations

BZD17C51P RUG (Primary Part): Suitable for general industrial and commercial applications requiring 51 V Zener regulation at 800 mW. Active product status with ROHS3 compliance and unlimited moisture sensitivity rating support standard PCB assembly processes.

BZD27C51P-E3-08 (Standard Substitute): Functionally equivalent to the primary part with identical electrical specifications and DO-219AB package compatibility. Extended lower operating temperature limit (-65°C versus -55°C) provides enhanced thermal margin for temperature-sensitive applications. ROHS3 compliance and unlimited MSL rating maintain compatibility with standard manufacturing processes.

BZD27C51P-HE3-08 (Automotive-Grade Substitute): Maintains all electrical and mechanical equivalence to the primary part while adding AEC-Q101 automotive qualification. This variant is required for applications subject to automotive industry standards and reliability requirements. Operating temperature range extends to -65°C, supporting demanding thermal environments.

Selection between substitute parts depends on application requirements: standard industrial use supports either BZD27C51P-E3-08 or BZD17C51P RUG; automotive applications mandate BZD27C51P-HE3-08.

Frequently Asked Questions (FAQ)

Q: Can BZD27C51P-E3-08 and BZD27C51P-HE3-08 be used interchangeably with BZD17C51P RUG?

A: Both Vishay parts are electrically and mechanically equivalent to the BZD17C51P RUG. All three devices share identical Zener voltage (51 V), power rating (800 mW), impedance (60 Ohms), and DO-219AB package specifications. Direct substitution is supported in circuit designs where the primary part is specified.

Q: What is the difference between BZD27C51P-E3-08 and BZD27C51P-HE3-08?

A: Both parts are electrically identical with matching 51 V Zener voltage and 800 mW power rating. The BZD27C51P-HE3-08 includes AEC-Q101 automotive qualification, making it suitable for automotive applications. The BZD27C51P-E3-08 is designated for general industrial use. Operating temperature ranges are identical (-65°C to 175°C) for both variants.

Q: Are all three parts packaged in DO-219AB?

A: Yes. The BZD17C51P RUG is supplied in Sub SMA (DO-219AB) packaging. Both substitute parts, BZD27C51P-E3-08 and BZD27C51P-HE3-08, use the standard DO-219AB (SMF) package. PCB footprints and reflow soldering profiles are compatible across all three devices.

Q: What is the operating temperature range for each part?

A: The BZD17C51P RUG operates from -55°C to 175°C. Both Vishay substitutes (BZD27C51P-E3-08 and BZD27C51P-HE3-08) extend the lower temperature limit to -65°C, providing a wider operating range while maintaining the same 175°C upper limit.

Q: Are all parts ROHS3 compliant?

A: Yes. The BZD17C51P RUG, BZD27C51P-E3-08, and BZD27C51P-HE3-08 are all ROHS3 compliant with unlimited moisture sensitivity level (MSL 1), supporting standard lead-free PCB assembly processes.

Q: Which part should be selected for automotive applications?

A: The BZD27C51P-HE3-08 is the appropriate selection for automotive applications due to its AEC-Q101 qualification. This certification ensures compliance with automotive industry reliability and quality standards. The other two parts are not qualified for automotive use.

Q: Do the substitute parts have the same electrical characteristics?

A: All three parts maintain identical Zener voltage (51 V), maximum power dissipation (800 mW), impedance (60 Ohms), reverse leakage current (1 µA @ 39 V), and forward voltage (1.2 V @ 200 mA). Electrical performance is equivalent across all devices.
