1PMT5923BT1

Single Zener Diodes Overview

The onsemi 1PMT5923BT1 is a 3.2 Watt Zener diode in the POWERMITE surface mount package, featuring an 8.2 V nominal breakdown voltage with ±5% tolerance (7.79 V to 8.61 V). It operates within a -55°C to +150°C temperature range and utilizes a DO-216AA footprint measuring 8.45 mm². The device includes integral locking tabs for thermal management and is supplied in 12 mm tape and reel packaging.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'BT1' corresponds to the 3,000-unit tape and reel configuration as documented in the datasheet. Confirm that the component meets the required Pb-Free specifications if applicable, noting that the 'G' suffix indicates availability in lead-free packages. Ensure compatibility with standard SMT assembly processes given the specified maximum case soldering temperature of 260°C for 10 seconds.

Single Zener Diodes Selection Notes

Select this component when a compact surface mount solution is required for voltage regulation up to 3.2 Watts. The 8.2 V nominal breakdown voltage suits circuits requiring precise clamping or reference levels. Consider the low profile and small footprint for space-constrained designs. Verify thermal requirements against the junction-to-ambient resistance values provided in the electrical characteristics section.

Single Zener Diodes Part Context

This part belongs to the 1PMT5920B series of 3.2 Watt plastic surface mount Zener diodes manufactured by onsemi. The series covers a wide range of breakdown voltages from 6.2 V to 47 V. All devices share the same POWERMITE package (DO-216AA) and mechanical characteristics, differing primarily in their specific Zener voltage ratings and test currents.

Single Zener Diodes Replacement Considerations

Compatible replacements include other members of the 1PMT5920B series such as the 1PMT5922BT1 or 1PMT5924BT1, provided their respective Zener voltages match the circuit requirements. Ensure any substitute maintains the same DO-216AA footprint and thermal performance capabilities.
