BZD17C47P RVG Equivalent & Substitute Parts

Part Overview

The BZD17C47P RVG is a 47 V, 800 mW Zener diode manufactured by Taiwan Semiconductor Corporation in Surface Mount Sub SMA packaging. This component is classified as an active product and is ROHS3 compliant. Zener diodes of this specification are used in voltage regulation and protection circuits where precise voltage reference and power dissipation characteristics are critical. Substitute parts may be required due to inventory availability, supply chain considerations, or specific packaging and qualification requirements for particular applications.

Substitute Part Grouping Explanation

Substitution of the BZD17C47P RVG is determined by electrical and mechanical parameter equivalence. The critical parameters that define substitutability are:

Electrical Parameters:

Zener voltage: 47 V nominal
Maximum power dissipation: 800 mW
Maximum impedance: 45 Ohms
Reverse leakage current: 1 µA @ 36 V
Forward voltage: 1.2 V @ 200 mA

Mechanical Parameters:

Package type: DO-219AB (Surface Mount)
Mounting configuration: Surface Mount

Compliance Parameters:

RoHS3 compliance
Moisture Sensitivity Level 1

All substitute parts listed maintain identical electrical specifications and package configuration. The BZD27C47P series from Vishay General Semiconductor - Diodes Division meets these requirements. Variants within this series differ in packaging format (Tape & Reel) and, in one case, automotive qualification (AEC-Q101).

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and identical electrical and mechanical specifications to the BZD17C47P RVG. Selection among the substitute options should be based on the following criteria:

Standard Industrial Applications: BZD27C47P-E3-08 and BZD27C47P-E3-18 are suitable for general industrial applications. Both parts maintain the full operating temperature range of -65°C to 175°C, which exceeds the original part's minimum temperature specification of -55°C.

Automotive Applications: BZD27C47P-HE3-08 is qualified to AEC-Q101 automotive standards and is the appropriate selection for automotive-grade circuit designs. This variant maintains identical electrical performance and temperature range while providing automotive qualification assurance.

Packaging and Inventory Considerations: All substitute parts are supplied in Tape & Reel (TR) packaging format. The original BZD17C47P RVG does not specify a packaging format designation. Tape & Reel packaging is standard for surface mount component distribution and is compatible with automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can BZD27C47P series parts directly replace the BZD17C47P RVG?

A: Yes. The BZD27C47P series parts listed maintain identical electrical specifications (47 V nominal Zener voltage, 800 mW maximum power, 45 Ohms maximum impedance, 1 µA reverse leakage, and 1.2 V forward voltage). All parts use the same DO-219AB package and Surface Mount configuration. Electrical and mechanical compatibility is confirmed.

Q: What is the difference between BZD27C47P-E3-08, BZD27C47P-E3-18, and BZD27C47P-HE3-08?

A: The three variants are electrically identical. BZD27C47P-HE3-08 includes AEC-Q101 automotive qualification, making it suitable for automotive applications. The suffix designations (-E3-08, -E3-18, -HE3-08) indicate different manufacturing batches or tape reel configurations but do not affect electrical performance or package compatibility.

Q: Does the operating temperature range difference affect substitution?

A: The substitute parts operate from -65°C to 175°C, while the original part operates from -55°C to 175°C. The substitute parts have an extended lower temperature range, which provides broader operational capability. This does not prevent substitution in applications designed for the original part's temperature range.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the BZD17C47P RVG.

Q: What packaging format should I specify when ordering substitute parts?

A: All substitute parts are supplied in Tape & Reel (TR) format, which is standard for surface mount component distribution and compatible with automated assembly equipment.

Q: Which substitute part should I select for automotive applications?

A: BZD27C47P-HE3-08 is qualified to AEC-Q101 automotive standards and is the appropriate selection for automotive circuit designs.
