MUN2134T1

Overview

The onsemi MUN2134T1 is a PNP Bias Resistor Transistor (BRT) housed in an SC-59 surface-mount package. It integrates a single transistor with a monolithic bias network consisting of a series base resistor (R1 = 22 kΩ) and a base-emitter resistor (R2 = 47 kΩ). Key electrical ratings include a collector-emitter voltage (VCEO) of 50 Vdc, a continuous collector current (IC) of 100 mAdc, and a total device dissipation (PD) of 338 mW at 25°C. The DC current gain (hFE) has a minimum value of 80. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Integrates a PNP transistor with a monolithic bias resistor network to replace discrete components.
• Reduces printed circuit board space and component count by combining the transistor and resistors into a single device.
• Features modified gull-winged leads in the SC-59 package to absorb thermal stress during soldering.

Applications

• General-purpose switching circuits
• Driver applications for loads such as relays or LEDs
• Logic level translation interfaces

Procurement Notes

Verify the specific ordering suffix and tape-and-reel quantity against the manufacturer's current documentation before purchase. Confirm that the SC-59 package dimensions match the target footprint requirements. Ensure compliance with RoHS directives if required by the final assembly specifications.

Selection Notes

Select this component when a PNP digital transistor with a 22 kΩ series base resistor and 47 kΩ base-emitter resistor is required. The 50 V collector-emitter voltage rating suits low-voltage logic applications. Consider the 100 mA continuous current capability for driving moderate loads directly.

Part Context

This part belongs to the MUN2111T1 Series of preferred devices from onsemi. The series offers various resistor combinations within the same SC-59 package to simplify circuit design across different logic families and drive requirements.

Replacement Considerations

Direct substitutes within the same series include MUN2130T1, MUN2131T1, MUN2132T1, MUN2133T1, MUN2136T1, and MUN2137T1, which share identical packaging and general electrical characteristics but differ in internal resistor values.
