JANKCA2N2920

Overview

The JANKCA2N2920 is a dual NPN bipolar junction transistor (BJT) array manufactured by Microchip Technology. It features a maximum collector-emitter voltage of 60V and a continuous collector current of 50mA. The device dissipates up to 350mW of power and operates within a junction temperature range of -65°C to 200°C. Key electrical characteristics include a DC current gain (hFE) of at least 300 at 1mA and 5V, with a saturation voltage of 300mV max at 100µA base and 1mA collector current. The collector cutoff current is limited to 10µA. Packaged in a TO-78-6 metal can for through-hole mounting, it complies with MIL-PRF-19500/355 standards.

Feature Summary

• Dual NPN configuration housed in a hermetically sealed TO-78-6 metal can package suitable for high-reliability environments.
• Qualified to military specifications (MIL-PRF-19500/355) ensuring performance under extreme thermal conditions.
• High DC current gain capability with low saturation voltage for efficient switching applications.

Applications

• Military-grade analog signal processing circuits
• High-temperature industrial control systems
• Aviation electronic subsystems requiring radiation-hardened or ruggedized components

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact qualification levels and testing requirements. Ensure compatibility with MIL-PRF-19500/355 standards if military grade is required. Confirm package integrity upon receipt due to the fragile nature of metal can packages. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a dual NPN configuration is required in a through-hole metal can package. Consider the 60V breakdown voltage and 50mA current limits for circuit design. Evaluate the wide operating temperature range (-65°C to 200°C) for harsh environment suitability. Compare hFE and Vce(sat) parameters against application requirements to ensure adequate gain and low loss.

Part Context

This part is based on the standard 2N2920 specification but includes specific manufacturing and qualification markings indicated by the JAN prefix and KCA suffix. It belongs to Microchip's portfolio of discrete semiconductors derived from legacy military designs. The TO-78-6 package provides robust mechanical protection and thermal dissipation compared to plastic alternatives.

Replacement Considerations

Direct replacements must match the TO-78-6 metal can package and dual NPN topology. Verify that substitute parts meet the same MIL-PRF-19500/355 qualification if military reliability is mandatory. Check pinout compatibility and electrical parameters such as Vceo and Icmax before substitution.
