BZD27C82P RVG Equivalent & Substitute Parts

Part Overview

The BZD27C82P RVG is a Zener diode rated at 82 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) format. The device is classified as Active product status and holds ROHS3 compliance with unlimited moisture sensitivity rating.

Substitute parts become necessary when the primary manufacturer part experiences supply constraints, extended lead times, or when design requirements call for alternative electrical or thermal characteristics within the same functional category. The BZD27C82P RVG maintains compatibility with equivalent Zener diodes that share identical nominal voltage, package format, and core electrical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the BZD27C82P RVG is determined by strict alignment with the following electrical and mechanical parameters:

Critical Matching Parameters:

Nominal Zener voltage: 82 V
Package format: DO-219AB (Sub SMA / SMF)
Surface mount configuration
Reverse leakage current: 1 µA @ 62 V
Forward voltage: 1.2 V @ 200 mA
RoHS3 compliance status
Moisture sensitivity level: 1 (Unlimited)

Acceptable Variation Parameters:

Power rating: Substitute parts rated at 800 mW (0.8 W) are acceptable as they remain within the operational envelope of the 1 W primary part
Impedance: Substitute parts with impedance specifications of 100 Ohms are acceptable as they represent improved performance characteristics
Operating temperature range: Extended ranges (-65°C to 175°C) are acceptable as they encompass the primary part's range
Tolerance: Substitute parts without specified tolerance remain functionally compatible

All three substitute parts (BZD27C82P-E3-08, BZD27C82P-HE3-08, BZD27C82P-M3-08) meet these substitution criteria and are manufactured by Vishay General Semiconductor - Diodes Division.

Engineering Selection Recommendations

BZD27C82P-E3-08 (Vishay): This substitute maintains full electrical equivalence with the primary part across all critical parameters. The 800 mW power rating operates within acceptable limits for applications designed for the 1 W primary device. The 100 Ohm impedance specification represents improved performance. ROHS3 compliance and unlimited moisture sensitivity align with the primary part. This variant is suitable for general industrial applications.

BZD27C82P-HE3-08 (Vishay): This variant carries AEC-Q101 automotive qualification in addition to meeting all electrical and compliance requirements of the primary part. The automotive-grade designation indicates enhanced reliability screening and qualification testing. This part is appropriate for automotive and mission-critical applications where enhanced qualification status is required. The 800 mW power rating and 100 Ohm impedance remain within acceptable operational parameters.

BZD27C82P-M3-08 (Vishay): This substitute provides full electrical compatibility with identical voltage, leakage current, and forward voltage specifications. The extended operating temperature range (-65°C to 175°C) encompasses the primary part's range. The 800 mW power rating and 100 Ohm impedance are consistent with other Vishay variants. This part is suitable for applications requiring extended low-temperature performance.

All three substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the primary BZD27C82P RVG device.

Frequently Asked Questions (FAQ)

Q: Can BZD27C82P-E3-08, BZD27C82P-HE3-08, and BZD27C82P-M3-08 be used interchangeably with BZD27C82P RVG?

A: Yes, all three Vishay variants are electrically and mechanically compatible with the BZD27C82P RVG. They share identical nominal Zener voltage (82 V), package format (DO-219AB), reverse leakage current (1 µA @ 62 V), and forward voltage characteristics (1.2 V @ 200 mA). The 800 mW power rating of the substitutes operates within the design envelope of the 1 W primary part.

Q: What is the difference between the three Vishay substitute parts?

A: The primary distinction is automotive qualification. BZD27C82P-HE3-08 carries AEC-Q101 automotive qualification, making it suitable for automotive and high-reliability applications. BZD27C82P-E3-08 and BZD27C82P-M3-08 are standard industrial-grade variants. All three share identical electrical specifications and DO-219AB packaging.

Q: Does the 800 mW power rating of the substitutes affect circuit performance compared to the 1 W primary part?

A: The 800 mW rating of the substitute parts is acceptable for applications designed around the 1 W primary device. The substitute parts maintain the same voltage regulation characteristics and leakage specifications. Circuit designs should verify that actual power dissipation remains below 800 mW during normal operation.

Q: Are all parts RoHS3 compliant?

A: Yes, the BZD27C82P RVG and all three substitute parts (BZD27C82P-E3-08, BZD27C82P-HE3-08, BZD27C82P-M3-08) are ROHS3 compliant. All parts also carry unlimited moisture sensitivity rating (MSL 1).

Q: What is the significance of the impedance difference between the primary part (200 Ohms) and the substitutes (100 Ohms)?

A: The lower impedance specification of the substitute parts (100 Ohms maximum) represents improved performance characteristics. Lower impedance indicates better voltage regulation stability and reduced dynamic resistance. This is a beneficial characteristic that does not compromise compatibility with the primary part.

Q: Can BZD27C82P-HE3-08 be used in non-automotive applications?

A: Yes, BZD27C82P-HE3-08 can be used in any application where BZD27C82P RVG is specified. The automotive qualification is an additional certification that does not restrict use in other applications. The automotive-grade part may be preferred in applications requiring enhanced reliability screening.

Q: Are there any temperature range considerations when substituting parts?

A: The substitute parts feature an extended operating temperature range (-65°C to 175°C) compared to the primary part (-55°C to 175°C). This extended range is fully compatible with the primary part's specifications and provides additional margin for low-temperature operation.
