CMSZDA36V TR PBFREE

Overview

The CMSZDA36V TR PBFREE is a surface mount dual silicon zener diode array manufactured by Central Semiconductor Corp. It features a common anode configuration housed in an SOT-323 package. The device provides a nominal zener voltage of 36 V with a power dissipation rating of 275 mW and a tolerance of ±5%. Key electrical characteristics include a maximum reverse leakage current of 1 µA at 2 V, a dynamic impedance (Zzt) of 40 Ohms, and a forward voltage of 900 mV at 10 mA. It operates within a temperature range of -65°C to +150°C.

Feature Summary

• Dual zener diode array with common anode configuration for space-efficient circuit design
• Surface mount construction in SOT-323 package suitable for automated assembly
• High thermal stability with extended operating temperature range up to 150°C

Applications

• Voltage reference circuits requiring dual stable potential sources
• Over-voltage protection stages in compact electronic modules

Procurement Notes

Verify the specific ordering suffix and packaging type when sourcing. Confirm RoHS compliance status and manufacturer lot codes upon receipt. Ensure storage conditions align with moisture sensitivity level requirements to maintain component integrity before soldering.

Selection Notes

Select this component for designs needing dual zener functions in minimal footprint. Compare dynamic impedance and leakage specifications against circuit requirements. Verify that the SOT-323 thermal performance meets the application's power dissipation needs under worst-case conditions.

Part Context

This part belongs to the CMSZDA series of surface mount dual zener diodes from Central Semiconductor. It complements single-channel zener options by providing two matched diodes in one package. The series covers various voltage ranges from 2.4 V to 47 V, offering designers flexibility in voltage selection without increasing board space.

Replacement Considerations

Direct substitutes may include other dual common anode zener arrays in SOT-323 packages with matching voltage and power ratings. Verify pinout compatibility and thermal characteristics before substitution. Cross-reference datasheets for impedance and leakage differences.
