DTA123JM3T5G

Overview

The DTA123JM3T5G is a single PNP digital transistor manufactured by onsemi, housed in an SOT-723-3 surface-mount package. It features a built-in bias resistor network with a typical input resistance of 4.7 kOhms and a resistor ratio of 0.1. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Power dissipation is rated at 260 mW, with an operating temperature range from -55°C to +150°C. The component is RoHS compliant and part of the DTA123JM3 series.

Feature Summary

• Integrates a single PNP transistor with a built-in bias resistor network for simplified circuit design.
• Utilizes a compact SOT-723-3 surface-mount package suitable for space-constrained applications.
• Operates within a wide temperature range, supporting environments from -55°C to +150°C.

Applications

• General-purpose switching applications requiring pre-biased PNP control.
• Interface circuits between logic outputs and load drivers.
• Battery management systems utilizing low-voltage PNP switching.

Procurement Notes

Verify the specific suffix T5G against the manufacturer's latest datasheet to confirm packaging and compliance details. Confirm that the DTA123JM3 variant matches the required resistor ratio and gain specifications for the target application. Cross-reference the ordering code with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when a PNP configuration with a 4.7 kOhm base resistor is required. Ensure the 50 V voltage rating and 100 mA current capacity exceed the circuit's maximum operational limits. Consider the SOT-723-3 footprint constraints during PCB layout planning.

Part Context

This part belongs to the DTA123 series of pre-biased transistors from onsemi. It serves as the PNP counterpart to NPN variants like the DTC123 series. The 'M3' suffix typically indicates lead-free and RoHS compliance, while 'T5G' denotes the specific tape and reel packaging format used for automated assembly.

Replacement Considerations

Compatible substitutes include other PNP digital transistors with similar 50 V ratings, 100 mA current capabilities, and integrated bias resistors. Verify pinout compatibility and thermal characteristics before substitution. Check for equivalent resistor ratios to maintain circuit stability.
