SMUN5133T1G

Overview

The SMUN5133T1G is a single PNP digital transistor manufactured by onsemi, designed for surface-mount applications. It integrates a built-in bias resistor network within an SC-70/SOT-323-3 package to simplify circuit design. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device features a typical input resistance of 4.7 kOhms with a resistor ratio of 0.1. It offers a minimum DC current gain (hFE) of 80 and supports a power dissipation of 310 mW. The component operates reliably across a temperature range from -55°C to +150°C.

Feature Summary

• Integrates a single PNP transistor with a built-in bias resistor network to reduce external component count.
• Utilizes a compact SC-70/SOT-323-3 surface-mount package for space-constrained designs.
• Provides high thermal stability with a maximum operating junction temperature of +150°C.

Applications

• General-purpose switching circuits requiring pre-biased PNP control.
• Interface logic level translation in embedded systems.
• Driver stages for low-current loads in consumer electronics.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status through the latest datasheet or environmental declaration, as regulatory updates may affect material declarations. Cross-reference the part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a single PNP digital transistor with a 4.7 kOhm base resistor is required. Ensure the application voltage does not exceed the 50 V VCEO rating and current demands remain within the 100 mA limit. Consider the SC-70 footprint constraints during PCB layout. Verify that the 310 mW power dissipation capability meets the thermal requirements of the target environment.

Part Context

This part belongs to the MUN5133 series of pre-biased transistors from onsemi. It serves as a PNP counterpart to NPN variants like the MUN5233T1G. The series is engineered to replace discrete resistor-transistor networks, offering consistent performance and reduced board space. It is widely used in portable devices and industrial controls where reliable switching is essential.

Replacement Considerations

Direct substitutes include other single PNP digital transistors with identical pinouts and similar electrical ratings, such as the MUN5133DW1T1G if a dual configuration is acceptable. Verify equivalent VCEO, IC, and R1 values before substitution. Consult manufacturer cross-reference guides for validated alternatives.
