Overview
The Microchip Technology 2N6989U is a hermetically sealed, ceramic surface-mount device consisting of four silicon NPN transistors. It utilizes a 20-pin package designed to minimize circuit board area and device weight. The component operates within a junction temperature range of -65°C to 200°C. Electrical characteristics include a maximum collector-emitter voltage of 50V and a maximum collector current of 800mA per transistor. Total power dissipation is rated at 1W. The device meets MIL-PRF-19500/559 qualification standards.
Feature Summary
- Hermetically sealed ceramic construction for environmental protection
- Quad NPN configuration in a compact surface-mount footprint
- Qualified to MIL-PRF-19500/559 military specifications
Applications
- General switching circuits
- Signal amplification
- Radio transmission systems
- Logic gate implementations
Procurement Notes
Verify the specific suffix (TX or TXV) against procurement requirements, as these indicate processing levels per MIL-PRF-19500/559. Confirm RoHS compliance status, as military-grade variants may differ from commercial standards. Ensure the ordering part number explicitly excludes processing suffixes if standard unprocessed units are required. Cross-reference datasheet revision dates with manufacturing change notices.
Selection Notes
Select this component when space constraints and weight reduction are critical design factors due to its small surface-mount package. Verify that the 50V collector-emitter voltage and 800mA current ratings align with circuit load requirements. Consider the 1W total power dissipation limit for thermal management. Ensure compatibility with MIL-PRF-19500/559 screening protocols if high reliability is necessary.
Part Context
The 2N6989U belongs to the 2N698 series of quad bipolar junction transistor arrays. It serves as the NPN counterpart to the PNP 2N6990. These devices are engineered for applications requiring multiple identical transistors in a single package. The series is characterized by hermetic sealing and military qualification, distinguishing it from standard commercial discrete transistors.
Replacement Considerations
Direct substitutes include the 2N6989UTX and 2N6989UTXV, which share the same electrical profile but differ in screening levels. Verify pinout compatibility before substitution. Alternative packages such as TO-116 exist for through-hole designs but require layout changes.
