Key Features

  • 6 V Zener voltage with 5% tolerance and 500 mW power dissipation in a compact SOD-123 (2-pin SMT) package for space-efficient voltage regulation circuits
  • Maximum dynamic impedance of 7 Ω and forward voltage of 0.9 V typical, ensuring stable clamping performance across a wide current range in signal protection applications
  • RoHS-compliant (e3 JEDEC code), AEC-Q101-qualified silicon Zener in SOD-123 package compatible with automated SMT reflow soldering for high-volume production

Applications

The MMSZ5233B-7-F is used as a precision 6 V voltage reference and transient clamp in consumer electronics, telecommunications equipment, and microcontroller GPIO protection circuits. Its 500 mW power rating and SOD-123 package make it suitable for compact switching power supplies, LED driver bias rails, and signal conditioning boards requiring a stable 6 V clamp in a minimal footprint. Industrial sensor interfaces and battery management circuits also employ this Zener for overvoltage protection on input lines rated up to 6 V.

Frequently Asked Questions

What is the maximum power dissipation and Zener voltage of the MMSZ5233B-7-F?

The MMSZ5233B-7-F is rated for 500 mW maximum power dissipation with a nominal Zener voltage of 6 V at 5% tolerance. This combination allows it to absorb transient overvoltage events on 5 V and 6 V supply rails without exceeding its thermal limits, making it a reliable clamp in GPIO protection, power supply, and voltage reference circuits using SOD-123 footprints.

How does the SOD-123 package of the MMSZ5233B-7-F benefit high-density PCB layouts?

The SOD-123 package of the MMSZ5233B-7-F measures approximately 2.68 mm x 1.17 mm, consuming minimal PCB area while providing 500 mW power dissipation and a 6 V clamp voltage. This compact 2-pin SMT footprint integrates easily into dense protection networks on smartphone charger boards, USB hub controllers, and industrial sensor interfaces where space is limited.

Is the MMSZ5233B-7-F suitable for automotive or industrial applications requiring RoHS compliance?

Yes, the MMSZ5233B-7-F carries a RoHS-compliant e3 JEDEC-609 code and uses a halogen-free silicon construction. Its 6 V, 500 mW Zener diode in SOD-123 package is suitable for industrial sensor protection, automotive accessory boards, and telecom line card overvoltage clamping where environmental compliance is mandatory. The 12-week factory lead time should be factored into supply chain planning for high-volume orders.
