Single Zener Diodes Procurement Notes

Verify that the specific suffix CUR-1/TR corresponds to the reel packaging format required for automated assembly processes. Confirm that the military grade designation aligns with project specifications. Ensure the DO-213AA footprint matches the design layout. Validate that the 47 V rating meets the circuit requirements without exceeding the 500 mW power limit under worst-case conditions.

Single Zener Diodes Selection Notes

Select this component when a surface-mount Zener diode with military qualification is required. The DO-213AA package offers a compact solution compared to through-hole alternatives like the C-1 variant. Consider the 105 Ohm impedance for noise-sensitive applications. The wide operating temperature range makes it suitable for extreme environmental conditions where standard commercial parts would fail.

Single Zener Diodes Part Context

This part belongs to the JAN series of Zener diodes produced by Microchip Technology. It is the surface-mount version of the traditional axial leaded 1N977 diode. The TXV suffix indicates enhanced testing and screening procedures beyond standard military grades, ensuring higher reliability for critical defense and aerospace applications.

Single Zener Diodes Replacement Considerations

JAN1N977CUR-1/TR is a lower-grade alternative within the same package. JANTXV1N977C-1 is a through-hole equivalent with identical electrical parameters but different mounting requirements.
