BZD27C11P RVG Equivalent & Substitute Parts

Part Overview

The BZD27C11P RVG is an 11 V, 1 W Zener diode manufactured by Taiwan Semiconductor Corporation in Surface Mount Sub SMA packaging (DO-219AB). This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating. Zener diodes of this specification are used in voltage regulation and protection circuits where precise voltage reference and power dissipation capabilities are required. Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit operation within the electrical and mechanical tolerances of alternative qualified sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BZD27C11P RVG is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Zener voltage nominal value: 11 V
• Maximum power dissipation: 1 W or greater
• Impedance (maximum): 7 Ohms or less
• Reverse leakage current: 4 µA @ 8.2 V
• Forward voltage: 1.2 V @ 200 mA
• Operating temperature range: Must encompass or exceed -55°C to 175°C

Mechanical Compatibility Criteria:

• Package type: DO-219AB (Sub SMA)
• Mounting type: Surface Mount
• Lead configuration: Compatible with Sub SMA footprint

Compliance Requirements:

• RoHS3 compliance mandatory
• REACH unaffected status
• Moisture sensitivity level: 1 (Unlimited)

The substitute parts BZD27C11P-E3-08 and BZD27C11P-M3-08 meet these criteria with the following considerations: both substitute parts operate at reduced maximum power (800 mW versus 1 W) but maintain all other electrical parameters within specification. Both substitutes extend the lower operating temperature limit to -65°C, providing enhanced thermal performance. All parts share identical package designation (DO-219AB), zener voltage (11 V), impedance (7 Ohms), and reverse leakage characteristics.

Parameter Comparison

Engineering Selection Recommendations

BZD27C11P-E3-08 Selection Criteria: This Vishay substitute maintains full electrical equivalence across all critical zener parameters. The 800 mW power rating accommodates applications where continuous power dissipation does not exceed this threshold. The extended lower temperature limit (-65°C) provides operational margin in cold environment applications. RoHS3 compliance and unlimited moisture sensitivity align with the main part specifications. This substitute is appropriate for designs where power dissipation remains below 800 mW and where Vishay component qualification is acceptable.

BZD27C11P-M3-08 Selection Criteria: This Vishay substitute from the BZD27-M series provides identical electrical performance to BZD27C11P-E3-08 with the same 800 mW power rating and extended temperature range. The primary distinction is series designation and manufacturing source within Vishay's product line. This substitute is appropriate for designs with equivalent power dissipation constraints and where the BZD27-M series qualification is acceptable. Significantly higher inventory availability (30,374 units) may provide supply chain advantages.

Power Dissipation Consideration: Applications requiring sustained power dissipation exceeding 800 mW must retain the BZD27C11P RVG main part specification. Substitute parts are not suitable for 1 W continuous operation.

Frequently Asked Questions (FAQ)

Q: Can BZD27C11P-E3-08 and BZD27C11P-M3-08 be used interchangeably with BZD27C11P RVG?

A: Both substitutes are electrically equivalent for applications where power dissipation does not exceed 800 mW. All three parts share identical zener voltage (11 V), impedance (7 Ohms), reverse leakage current (4 µA @ 8.2 V), and forward voltage characteristics (1.2 V @ 200 mA). Package compatibility is confirmed (DO-219AB). Substitution is valid only when circuit design ensures power dissipation remains below 800 mW.

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

A: The main part (BZD27C11P RVG) is rated for 1 W maximum power dissipation, while both substitutes are rated for 800 mW. The substitutes extend the lower operating temperature limit to -65°C compared to -55°C for the main part. All other electrical and mechanical parameters are identical.

Q: Are the substitute parts available in the same packaging format?

A: No. The main part is supplied in Cut Tape (CT) format, while both substitutes are supplied in Tape & Reel (TR) format. Both formats are compatible with automated assembly processes, though reel quantities and handling procedures differ.

Q: Do all three parts meet the same compliance standards?

A: Yes. BZD27C11P RVG, BZD27C11P-E3-08, and BZD27C11P-M3-08 are all RoHS3 compliant, REACH unaffected, and carry unlimited moisture sensitivity rating (MSL 1).

Q: What is the difference between BZD27C11P-E3-08 and BZD27C11P-M3-08?

A: Both parts are manufactured by Vishay and share identical electrical specifications and package designation. The primary differences are series designation (BZD27C versus BZD27-M) and inventory availability. BZD27C11P-M3-08 has significantly higher stock levels (30,374 units versus 4,300 units).

Q: Can I use a substitute part if my circuit is designed for 1 W power dissipation?

A: No. If your circuit design requires 1 W continuous power dissipation, the substitute parts rated at 800 mW are not suitable. The main part BZD27C11P RVG must be used.

Q: Are there any temperature-related advantages to using the substitute parts?

A: The substitute parts extend the lower operating temperature limit to -65°C compared to -55°C for the main part. This provides a 10°C margin for cold environment applications. The upper temperature limit remains 175°C for all three parts.
