Overview
The MMBZ27VDA-G3-08 is a dual common-anode Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It is housed in an SOT-23-3 surface-mount package and is qualified to the AEC-Q101 automotive standard. The device features a nominal Zener voltage of 27 V with a maximum power dissipation of 300 mW. Key electrical parameters include a typical reverse standoff voltage of 22 V, a minimum breakdown voltage of 25.65 V, and a maximum clamping voltage of 38 V at a peak pulse current of 1 A (10/1000µs). It operates within a temperature range of -55°C to +150°C TJ.
Feature Summary
- Dual common-anode configuration for efficient space-saving circuit design
- Automotive-grade reliability certified under AEC-Q101 standards
- High thermal stability supporting operation up to 150°C junction temperature
Applications
- Protection of sensitive electronic components in automotive systems
- Voltage reference applications requiring dual-channel regulation
- Clamping circuits in high-reliability industrial electronics
Procurement Notes
Verify the specific suffix G3-08 against official Vishay documentation to confirm RoHS compliance and packaging details. Ensure the selected component matches the required automotive qualification level. Cross-reference the datasheet revision date to validate parameter accuracy before integration into final designs.
Selection Notes
Select this component when a dual Zener solution with common anode topology is required for automotive or industrial environments. Consider the 300 mW power rating and SOT-23-3 footprint constraints during PCB layout. Verify that the 27 V nominal voltage aligns with the target circuit protection thresholds.
Part Context
This part belongs to the MMBZ27VDA series of small-signal Zener diodes from Vishay. It shares the same functional characteristics as the MMBZ27VDA-HE3_A-18 variant but differs in packaging and ordering suffixes. Both are designed for surface-mount assembly and offer similar electrical performance profiles.
Replacement Considerations
The MMBZ27VDA-HE3_A-18 serves as a verified alternative within the same product family. Ensure pinout compatibility and identical electrical specifications when substituting. Confirm that the replacement maintains the required AEC-Q101 automotive qualification status.
