BZX84C6V2 Equivalent & Substitute Parts

Part Overview

The BZX84C6V2 is a surface mount Zener diode manufactured by onsemi, rated at 6.2 V nominal Zener voltage with 350 mW maximum power dissipation in a SOT-23-3 package. This part is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and production continuity. Equivalent parts maintain identical electrical specifications, while substitute parts offer compatible functionality with variations in power rating, tolerance, or packaging configuration.

Engineering Selection Recommendations

Direct onsemi Equivalents (Recommended for Continuity):

BZX84C6V2ET1G, BZX84C6V2LT1G, and BZX84C6V2LT3G are active onsemi products with identical electrical specifications to the obsolete BZX84C6V2. These parts maintain the 6.2 V nominal Zener voltage, ±6% tolerance, 10 Ohm impedance, and SOT-23-3 package. The primary difference is reduced maximum power dissipation (225 mW versus 350 mW) and extended operating temperature range (-65°C to 150°C versus -55°C to 150°C). Selection among these three variants depends on packaging requirements: ET1G for Tape & Reel, LT1G for Cut Tape & Digi-Reel, and LT3G for Tape & Reel.

Automotive-Grade Alternatives (AEC-Q101 Qualified):

SZBZX84C6V2LT1G and SZBZX84C6V2LT3G are automotive-grade onsemi Zener diodes with AEC-Q101 qualification. These parts are electrically identical to the standard BZX84C6V2 equivalents but carry automotive qualification. Selection is appropriate for applications requiring automotive-grade components.

Higher Power Alternatives (Upgraded Performance):

BZX84C6V2-7-F (Diodes Incorporated) and BZX84B6V2-7-F (Diodes Incorporated) offer 300 mW maximum power dissipation, exceeding the original 350 mW specification. BZX84B6V2-7-F provides tighter ±2% tolerance. These parts are suitable for applications where higher power dissipation capability is beneficial.

Nexperia Alternatives (Precision Tolerance Options):

BZX84-A6V2,215 (Nexperia USA Inc.) provides ±1% tolerance with 250 mW power rating. BZX84-C6V2,215 (Nexperia USA Inc.) and BZX84-C6V2,235 (NXP Semiconductors) offer ±5% tolerance with 250 mW power rating. These alternatives are suitable for applications requiring tighter tolerance specifications.

All substitute parts maintain SOT-23-3 package compatibility, identical reverse leakage current, forward voltage characteristics, and impedance specifications. All active alternatives carry RoHS3 compliance and REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can BZX84C6V2ET1G, BZX84C6V2LT1G, and BZX84C6V2LT3G be used interchangeably with the obsolete BZX84C6V2?

A: Yes. These three onsemi parts are electrically equivalent to the BZX84C6V2 with identical Zener voltage (6.2 V), tolerance (±6%), impedance (10 Ohms), and forward voltage characteristics. The differences are packaging configuration (Tape & Reel versus Cut Tape & Digi-Reel) and reduced maximum power dissipation (225 mW versus 350 mW). Selection depends on procurement and assembly requirements.

Q: What is the difference between standard BZX84C6V2 equivalents and SZBZX84C6V2 variants?

A: SZBZX84C6V2LT1G and SZBZX84C6V2LT3G are automotive-grade versions with AEC-Q101 qualification. Electrical specifications are identical to standard equivalents. Automotive-grade parts are required for applications subject to automotive industry standards and qualification requirements.

Q: Why do some substitute parts have lower maximum power ratings (225 mW) than the original BZX84C6V2 (350 mW)?

A: The onsemi active equivalents (BZX84C6V2ET1G, BZX84C6V2LT1G, BZX84C6V2LT3G) specify 225 mW maximum power dissipation. This represents a design change in the active product line. Applications requiring higher power dissipation should select BZX84C6V2-7-F or BZX84B6V2-7-F (300 mW) from Diodes Incorporated.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All active substitute parts listed carry RoHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: What is the significance of tolerance variations (±1%, ±2%, ±5%, ±6%) among substitute parts?

A: Tolerance specifies the allowable deviation from the nominal 6.2 V Zener voltage. Tighter tolerance (±1% or ±2%) provides more precise voltage regulation, while standard tolerance (±5% or ±6%) is acceptable for general applications. Selection depends on circuit requirements for voltage accuracy.

Q: Can Nexperia BZX84-A6V2,215 and BZX84-C6V2,215 be used as direct replacements?

A: Yes. Both Nexperia parts maintain the 6.2 V nominal Zener voltage, 10 Ohm impedance, and SOT-23-3 package. BZX84-A6V2,215 offers ±1% tolerance with 250 mW power rating. BZX84-C6V2,215 offers ±5% tolerance with 250 mW power rating. Both carry AEC-Q101 automotive qualification.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in three packaging configurations: Tape & Reel (TR) for automated assembly, Cut Tape (CT) & Digi-Reel for manual or semi-automated assembly, and Bulk for custom packaging. Selection depends on procurement volume and assembly process requirements.

Q: Are there inventory considerations when selecting substitute parts?

A: Yes. Inventory availability varies significantly among substitute parts. BZX84C6V2LT1G has the highest inventory (95,400 pcs), while BZX84C6V2LT3G has lower availability (1,423 pcs). Procurement planning should account for inventory levels and lead times.
