BZD27C68P RVG Equivalent & Substitute Parts

Part Overview

The BZD27C68P RVG is an active-status Zener diode manufactured by Taiwan Semiconductor Corporation, rated for 68 V nominal Zener voltage with 1 W maximum power dissipation. This component is designed for surface mount applications in the DO-219AB (Sub SMA) package. Substitute parts are necessary when the primary manufacturer part becomes unavailable, when alternative packaging formats are required for production processes, or when inventory constraints necessitate sourcing from qualified alternative manufacturers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the BZD27C68P RVG is permissible with parts that maintain the following critical parameters:

Zener Voltage (Vz): 68 V nominal
Package / Case: DO-219AB (surface mount)
Impedance (Zzt): 80 Ohms maximum
Reverse Leakage Current: 1 µA @ 51 V
Forward Voltage (Vf): 1.2 V @ 200 mA maximum
RoHS Compliance: ROHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts listed below are manufactured by Vishay General Semiconductor - Diodes Division and share the BZD27C series base product designation. All substitute parts operate within the same electrical specifications and package footprint. The primary differences among substitute parts relate to maximum power rating (800 mW versus 1 W) and packaging format (Cut Tape, Digi-Reel, or Tape & Reel). These differences do not affect functional compatibility in applications where the 800 mW power rating is sufficient.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full compliance with ROHS3 and REACH regulations. The BZD27C68P RVG and its substitutes are functionally equivalent for applications requiring 68 V Zener regulation in the DO-219AB surface mount package.

Power Rating Consideration: The main part BZD27C68P RVG is rated for 1 W maximum power dissipation, while all Vishay substitute parts are rated for 800 mW. Selection of substitute parts is appropriate for applications where the thermal design does not require the full 1 W capability. Applications requiring sustained operation at or near 1 W power dissipation should retain the original BZD27C68P RVG specification.

Operating Temperature Range: Vishay substitute parts extend the lower operating temperature limit to -65°C compared to the -55°C minimum of the main part. This extended range provides additional margin for low-temperature applications.

Packaging Format: The three substitute parts differ in packaging format. BZD27C68P-E3-08 is available in Cut Tape and Digi-Reel formats suitable for manual or semi-automated assembly. BZD27C68P-E3-18 and BZD27C68P-M3-08 are supplied in Tape & Reel format for high-volume automated production. Selection should align with assembly process requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can BZD27C68P-E3-08, BZD27C68P-E3-18, and BZD27C68P-M3-08 be used interchangeably with BZD27C68P RVG?

A: Yes, these parts are electrically and mechanically compatible. All maintain 68 V Zener voltage, 80 Ohms impedance, identical reverse leakage characteristics, and the same DO-219AB package footprint. The primary differences are power rating (800 mW versus 1 W) and packaging format. Selection depends on application power requirements and production process compatibility.

Q: What is the impact of the 800 mW power rating on substitute parts compared to the 1 W main part?

A: The 800 mW rating on substitute parts is 20% lower than the 1 W main part. For applications operating below 800 mW, no performance difference exists. Applications requiring sustained operation at power levels between 800 mW and 1 W should use the original BZD27C68P RVG or verify that thermal design accommodates the lower rating.

Q: Are all parts ROHS3 compliant and suitable for regulated markets?

A: Yes. The main part BZD27C68P RVG and all substitute parts are ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements for restricted substance use in electronics manufacturing and distribution.

Q: What packaging formats are available, and how do they affect assembly?

A: BZD27C68P-E3-08 is supplied in Cut Tape and Digi-Reel formats for manual or semi-automated pick-and-place assembly. BZD27C68P-E3-18 and BZD27C68P-M3-08 are supplied in Tape & Reel format for high-speed automated assembly lines. Selection should match the assembly equipment and production volume requirements.

Q: Do the substitute parts have different operating temperature ranges?

A: Yes. The main part BZD27C68P RVG operates from -55°C to 175°C. All Vishay substitute parts extend the lower limit to -65°C, providing a 10°C margin for low-temperature applications. The upper limit of 175°C is identical across all parts.

Q: Are there any moisture sensitivity concerns with these parts?

A: No. All parts, including the main BZD27C68P RVG and all substitutes, have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during storage or assembly.
