Engineering Selection Recommendations

BZX84C6V8LT1G is an active equivalent suitable for standard applications. This part maintains all electrical parameters within specification and is available in Cut Tape and Digi-Reel packaging. ROHS3 compliance and unlimited moisture sensitivity rating align with modern manufacturing standards.

BZX84C6V8LT3G provides identical electrical specifications to BZX84C6V8LT1G with Tape & Reel packaging. Selection between LT1G and LT3G variants depends on procurement and assembly requirements.

SZBZX84C6V8ET1G and SZBZX84C6V8LT1G are automotive-grade alternatives qualified to AEC-Q101 standard. These parts are suitable for applications requiring automotive qualification. SZBZX84C6V8LT1G specifies reverse leakage at 2 V, providing tighter leakage specification than the original MAZ30680ML.

All substitute parts exceed the original 200 mW power rating at 225 mW, providing enhanced thermal margin. All maintain identical zener voltage, tolerance, impedance, and forward voltage characteristics. All are ROHS3 compliant and carry unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can BZX84C6V8LT1G directly replace MAZ30680ML in existing designs?

A: Yes. BZX84C6V8LT1G maintains identical electrical specifications for zener voltage (6.8 V ±6%), impedance (15 Ohms maximum), reverse leakage (2 µA @ 4 V), and forward voltage (900 mV @ 10 mA). Both use SOT-23-3 (TO-236) surface mount packaging. The substitute provides 225 mW power rating compared to the original 200 mW, offering improved thermal performance.

Q: What is the difference between BZX84C6V8LT1G and BZX84C6V8LT3G?

A: Both parts are electrically identical. The primary difference is packaging format: BZX84C6V8LT1G is supplied in Cut Tape and Digi-Reel, while BZX84C6V8LT3G is supplied in Tape & Reel. Selection depends on assembly line requirements and procurement preferences.

Q: When should automotive-grade alternatives be selected?

A: SZBZX84C6V8ET1G and SZBZX84C6V8LT1G are qualified to AEC-Q101 automotive standard. These parts are specified for applications requiring automotive qualification or operating in automotive environments. Both maintain identical electrical specifications to standard-grade alternatives.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. The original MAZ30680ML does not specify RoHS status. All substitutes carry REACH Unaffected designation.

Q: What is the significance of reverse leakage specification differences?

A: SZBZX84C6V8LT1G specifies reverse leakage at 2 µA @ 2 V, compared to 2 µA @ 4 V for other parts. This represents a tighter leakage specification at lower voltage, providing enhanced performance in low-voltage bias applications. All parts remain functionally equivalent within the specified parameter ranges.

Q: Is the increased power rating (225 mW vs. 200 mW) significant?

A: The 225 mW rating in substitute parts provides 12.5% additional thermal margin compared to the original 200 mW specification. This allows for improved reliability in thermal stress conditions while maintaining identical electrical performance at rated specifications.
