2N708

Single Bipolar Transistors Overview

The Microchip Technology 2N708 is a small-signal NPN silicon bipolar junction transistor designed for switching applications. It features a collector-emitter voltage of 15 V and a total power dissipation of 360 mW at 25°C ambient temperature. The device operates within a junction temperature range of -65°C to +200°C. It utilizes a TO-18 (TO-206AA) metal cylindrical package with three wire leads. The minimum DC current gain (hFE) is specified at 40.

Single Bipolar Transistors Feature Summary

• NPN silicon construction optimized for high-speed switching operations
• Qualified per MIL-PRF-19500/312 standards for JAN and JANTX levels
• Robust thermal performance with extended operating junction temperature up to 200°C

Single Bipolar Transistors Applications

• General-purpose signal switching circuits
• Military and aerospace electronic systems requiring MIL-PRF-19500/312 compliance
• Low-voltage amplifier stages in discrete semiconductor designs

Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer source, as the 2N708 designation is utilized by multiple vendors including Central Semiconductor and STMicroelectronics. Confirm that the received component matches the required MIL-PRF-19500/312 qualification level if military-grade reliability is mandated. Check RoHS compliance status, as some listings indicate non-compliance. Ensure the package type corresponds to the legacy TO-18 specification for proper mechanical integration.

Single Bipolar Transistors Selection Notes

Select this component when a ruggedized NPN switching transistor with high thermal tolerance is required. The 15 V collector-emitter rating suits low-voltage logic and control interfaces. Consider the through-hole TO-18 package constraints for PCB layout. Evaluate the 360 mW power dissipation limit against circuit load requirements to ensure safe operation without excessive heat sinking.

Single Bipolar Transistors Part Context

The 2N708 belongs to the family of standard NPN silicon switching transistors historically produced under military specifications. It serves as a discrete semiconductor solution for reliable signal control in harsh environments. The part represents a legacy component often retained in existing designs requiring proven radiation and thermal stability characteristics.

Single Bipolar Transistors Replacement Considerations

Cross-reference with other manufacturers' 2N708 equivalents such as those from Central Semiconductor or STMicroelectronics. Verify pinout compatibility and electrical parameter alignment before substitution. Note that availability may vary significantly across suppliers due to the component's legacy status.
