BZD27C47P RVG Equivalent & Substitute Parts

Part Overview

The BZD27C47P RVG is a 47 V, 1 W Zener diode manufactured by Taiwan Semiconductor Corporation in Sub SMA surface mount packaging. This component is classified as an active product and is RoHS3 compliant. The BZD27C47P RVG serves voltage regulation and protection functions in electronic circuits requiring 47 V Zener reference characteristics.

Substitute parts are identified based on matching electrical specifications including nominal Zener voltage, impedance characteristics, reverse leakage current, forward voltage drop, and thermal operating range. Mechanical compatibility is ensured through identical package designation (DO-219AB) and surface mount mounting type.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BZD27C47P RVG are qualified based on the following electrical and mechanical criteria:

Electrical Matching Parameters:

• Nominal Zener voltage: 47 V
• Impedance (Max): 45 Ohms
• Current - Reverse Leakage @ Vr: 1 µA @ 36 V
• Voltage - Forward (Vf) (Max) @ If: 1.2 V @ 200 mA

Mechanical Compatibility:

• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Supplier Device Package: Sub SMA or DO-219AB (SMF)

Compliance Requirements:

• RoHS3 Compliant
• REACH Unaffected
• ECCN: EAR99

The substitute parts identified (BZD27C47P-E3-08, BZD27C47P-E3-18, and BZD27C47P-HE3-08) meet all electrical specifications and mechanical requirements. The primary difference between the main part and substitutes is the maximum power rating: the main part is rated at 1 W, while substitute parts are rated at 800 mW. This represents a reduction in power dissipation capability. Additionally, substitute parts operate across an extended lower temperature range (-65°C minimum versus -55°C minimum).

Parameter Comparison

Engineering Selection Recommendations

BZD27C47P-E3-08 and BZD27C47P-E3-18: These Vishay General Semiconductor parts are functionally equivalent to the BZD27C47P RVG for applications where the 800 mW power rating is sufficient. Both parts maintain identical electrical characteristics including Zener voltage, impedance, reverse leakage, and forward voltage specifications. The extended operating temperature range (-65°C to 175°C) provides additional thermal margin compared to the main part. Both are RoHS3 compliant and REACH unaffected. Selection between these two variants depends on tape reel configuration and inventory availability.

BZD27C47P-HE3-08: This Vishay variant is qualified to AEC-Q101 automotive standards and carries automotive grade designation. It is suitable for applications requiring automotive-grade component certification while maintaining all electrical and mechanical compatibility with the BZD27C47P RVG. The 800 mW power rating and extended temperature range apply identically to the standard Vishay variants.

Power Rating Consideration: Applications requiring continuous power dissipation exceeding 800 mW must retain the BZD27C47P RVG (1 W rating). For applications operating within 800 mW maximum dissipation, all substitute parts are electrically and mechanically compatible.

Frequently Asked Questions (FAQ)

Q: Can BZD27C47P-E3-08, BZD27C47P-E3-18, and BZD27C47P-HE3-08 be used interchangeably with BZD27C47P RVG?

A: These parts are mechanically and electrically compatible for applications where power dissipation does not exceed 800 mW. All parts share identical Zener voltage (47 V), impedance (45 Ohms), reverse leakage current (1 µA @ 36 V), and forward voltage characteristics (1.2 V @ 200 mA). Package designation (DO-219AB) and surface mount mounting type are identical across all variants.

Q: What is the primary difference between the main part and substitute parts?

A: The BZD27C47P RVG is rated for 1 W maximum power dissipation, while substitute parts are rated for 800 mW. Additionally, substitute parts operate across an extended lower temperature range (-65°C minimum versus -55°C minimum). All other electrical specifications remain identical.

Q: When should BZD27C47P-HE3-08 be selected over other substitutes?

A: BZD27C47P-HE3-08 is selected when automotive-grade component certification is required. This part carries AEC-Q101 qualification and automotive grade designation. Electrical and mechanical specifications are identical to other Vishay variants.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. BZD27C47P-E3-08, BZD27C47P-E3-18, and BZD27C47P-HE3-08 are all RoHS3 compliant and REACH unaffected, matching the compliance status of the BZD27C47P RVG.

Q: What is the significance of the DO-219AB package designation?

A: DO-219AB is the standardized package designation for Sub SMA surface mount Zener diodes. All parts in this comparison use identical DO-219AB packaging, ensuring mechanical compatibility in PCB assembly and reflow soldering processes.

Q: Can substitute parts be used in high-power applications?

A: Applications requiring continuous power dissipation exceeding 800 mW must use the BZD27C47P RVG (1 W rating). Substitute parts are limited to 800 mW maximum dissipation and will not function reliably in higher power applications.
