Overview
The MMBZ16VALT1G is a dual-channel, unidirectional transient voltage suppression (TVS) diode manufactured by onsemi. It features a Zener breakdown voltage of 15.2 V and a working voltage of 13 V. The device handles a peak pulse current of 1.7 A with a maximum clamping voltage of 23 V under standard test conditions. It offers a peak pulse power dissipation rating of 40 W and provides electrostatic discharge protection up to 30 kV via the human body model. The component operates within a temperature range of -55°C to +150°C and is housed in an SC-59-3 (SOT-23-3) surface-mount package.
Feature Summary
- Dual-channel configuration for simultaneous protection of multiple signal lines
- High-energy transient suppression capability with 40 W peak pulse power rating
- Robust electrostatic discharge protection rated at 30 kV contact discharge
Applications
- Protection of high-speed data interfaces against ESD events
- Surge suppression in portable electronic devices
- Transient voltage limiting in automotive communication circuits
Procurement Notes
Verify the specific ordering suffix to ensure the correct tape and reel quantity matches production requirements. Confirm that the RoHS compliance status aligns with regional regulatory standards for the intended market. Check the datasheet for any recent product change notices that may affect pinout or electrical characteristics before finalizing procurement specifications.
Selection Notes
Select this component when dual-line protection is required in a compact SOT-23 footprint. Ensure the operating voltage of the protected circuit remains below the 13 V working voltage threshold. Verify that the expected transient energy does not exceed the 40 W peak pulse power rating to maintain device reliability during fault conditions.
Part Context
This part belongs to the MMBZ16V series of dual TVS diodes from onsemi. It shares the same SC-59-3 package form factor as other members of the family but differs in breakdown voltage and channel configuration. The series is designed for space-constrained applications requiring efficient ESD and surge protection solutions.
Replacement Considerations
Direct substitutes must match the 15.2 V breakdown voltage, 40 W power rating, and SOT-23-3 package. Verify polarity compatibility, as this is a unidirectional device. Cross-reference with other dual-channel TVS diodes from different manufacturers only if electrical parameters and thermal performance are equivalent.
