JAN2N2920U/TR

Overview

The JAN2N2920U/TR is an NPN silicon dual transistor qualified per MIL-PRF-19500/355. It features a collector-emitter voltage (VCEO) of 60 Vdc and a collector current (IC) of 30 mAdc. Total power dissipation is 350 mW at +25°C ambient temperature. The device operates within a junction temperature range of -65 to +200 °C. Forward-current transfer ratio (hFE) ranges from 175 to 1000 at IC = 1.0mAdc and VCE = 5.0Vdc. Collector-emitter saturation voltage (VCE(sat)) is 0.3 Vdc at IC = 1.0mAdc and IB = 100μAdc.

Feature Summary

• Dual NPN configuration in a single package for space-constrained designs
• Qualified to MIL-PRF-19500/355 for military reliability standards
• Extended operating junction temperature range up to +200 °C
• High forward-current transfer ratio suitable for low-level signal amplification

Applications

• Military aerospace circuitry requiring radiation-hardened or high-reliability components
• Low-noise amplifier stages in communication systems
• Precision switching applications in harsh environments

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and qualification level. Ensure that the procurement channel provides traceability to MIL-PRF-19500/355 standards. Confirm RoHS status and environmental compliance requirements prior to purchase, as military-grade parts may have specific regulatory constraints.

Selection Notes

Select this component when a dual NPN transistor with high gain and wide temperature tolerance is required. Compare hFE ranges and saturation voltages against circuit requirements. Consider the TO-78 surface mount package dimensions for PCB layout compatibility. Verify thermal derating curves if operating above +25°C ambient temperature.

Part Context

This part belongs to the 2N2919/2N2920 family of NPN silicon dual transistors. The 'JAN' prefix indicates it is a JANS/JANTX qualified device meeting military specifications. The 'U' suffix denotes the surface mount TO-78 package variation. It serves as a ruggedized alternative to commercial equivalents for defense and aerospace applications.

Replacement Considerations

Direct replacements include other MIL-PRF-19500/355 qualified devices such as the JAN2N2920 or JAN2N2920L. Verify pinout compatibility and electrical parameters before substitution. Surface mount variants like JAN2N2919U/TR offer similar functionality in compatible packages.
