Overview
The J107 is an N-Channel Junction Field-Effect Transistor (JFET) switch manufactured by onsemi. It is housed in a TO-92 three-lead through-hole package and utilizes silicon technology. The device features a gate-source breakdown voltage of -25 V and a drain-source on resistance of 8 Ohms at zero gate voltage. Maximum power dissipation is rated at 625 mW, with a junction-to-ambient thermal resistance of 357 °C/W. The component operates within a temperature range of -55°C to +150°C.
Feature Summary
- Designed for analog or digital switching applications requiring low on-resistance
- Single N-Channel configuration suitable for general-purpose switching tasks
- Robust thermal performance with high maximum junction temperature rating
Applications
- Analog signal switching circuits
- Digital logic interface switching
- Low-voltage DC load control
Procurement Notes
Verify the current production status before procurement as this component may be discontinued. Confirm that the TO-92 package dimensions match your PCB footprint requirements. Ensure that the 8 Ohm on-resistance meets the specific voltage drop constraints of your application design. Check for updated ordering suffixes due to manufacturer integration changes.
Selection Notes
Select the J107 when a low-cost, single-channel N-Channel JFET switch is required for moderate current applications. Compare its 8 Ohm on-resistance against other variants like the J105 or J106 if lower resistance is needed. Ensure the circuit design accommodates the -4.5 V maximum gate-source cut-off voltage to guarantee proper turn-off characteristics.
Part Context
The J107 belongs to a family of N-Channel JFET switches that includes the J105 and J106 models. These components share similar packaging and basic electrical structures but differ in their specific on-resistance and cut-off voltage specifications. This series is designed for cost-effective switching solutions in consumer and industrial electronics.
Replacement Considerations
The J105 and J106 are direct functional siblings within the same datasheet. The J105 offers lower on-resistance (3 Ohms), while the J106 provides intermediate characteristics (6 Ohms). Verify pinout compatibility and thermal derating requirements when substituting between these variants.
