PDTA123JT,215

PDTA123JT,215 Description

The PDTA123JT,215 from Nexperia is a surface-mount, pre-biased PNP bipolar transistor in a compact TO-236AB (SOT-23) package, designed for automotive-grade applications. It integrates a 2.2 kΩ base resistor (R1) and a 47 kΩ emitter-base resistor (R2), simplifying circuit design by eliminating external biasing components. With a collector-emitter breakdown voltage of 50V and a maximum collector current (Ic) of 100mA, this device is optimized for low-power switching and amplification. Its high DC current gain (hFE ≥ 100 @ 10mA, 5V) ensures efficient signal amplification, while the low Vce saturation (100mV @ 250µA, 5mA) minimizes power loss in switching applications.

PDTA123JT,215 Features

• Pre-biased design: Integrated resistors reduce component count and PCB space.
• Automotive-grade reliability: Meets stringent AEC-Q101 standards for harsh environments.
• Low leakage current: Collector cutoff current (ICBO) of 100nA ensures energy efficiency.
• High gain linearity: Stable performance across 10mA to 100mA operating range.
• RoHS3 & REACH compliant: Environmentally friendly and suitable for global markets.
• MSL 1 (Unlimited): No baking required before assembly, streamlining production.
