Single Zener Diodes Procurement Notes

Verify that the specific suffix /TR indicates tape-and-reel packaging rather than bulk units when ordering. Confirm compliance with MIL-PRF-19500/127 standards for the JANTXV grade. Ensure the procurement documentation explicitly states the 9.1 V Zener voltage and 5% tolerance to match design requirements. Validate that the component is sourced from authorized channels to guarantee authenticity.

Single Zener Diodes Selection Notes

Select this component when a precise 9.1 V reference is required in space-constrained axial packages. Consider the low Zener impedance for applications needing tight voltage stability under varying load conditions. Evaluate the thermal derating curve if operating above +50°C to ensure power dissipation limits are not exceeded. Compare against JAN or JANTX grades if military qualification levels can be relaxed.

Single Zener Diodes Part Context

This part belongs to the 1N757 series of Zener diodes, widely used in defense and aerospace sectors. The JANTXV designation signifies enhanced screening and testing beyond standard military specifications. It serves as a critical passive element in voltage regulation and overvoltage protection networks where long-term stability is paramount.

Single Zener Diodes Replacement Considerations

Direct substitutes include JAN1N757A-1 and JANTX1N757A-1, which share identical electrical parameters but may differ in manufacturing lot screening intensity. Verify package compatibility and pinout alignment before substitution.
