This file is the MOTOROLA BUID42D data sheet, which introduces the features and characteristics of the product
The Motorola BUD42D is a state-of-the-art bipolar transistor designed for light ballast applications. It features tight dynamic characteristics and lot-to-lot minimum spread, making it ideal for specific electronic circuits. The device integrates a Free Wheeling Diode and offers two case styles: Case 369-07 for insertion mode and Case 369A-13 for surface mount mode.
Key specifications include a collector-emitter sustaining voltage of 350 Vdc, a collector current of 4 Adc, and a total device dissipation of 25 Watts. The datasheet provides detailed electrical characteristics, typical static and switching characteristics, and safe operating area curves for both resistive and inductive loads.
| Collector—Emitter Sustaining Voltage | 350 Vdc |
|---|---|
| Collector Current — Continuous | 4 Adc |
| Total Device Dissipation | 25 Watt |
| Operating and Storage Temperature | -65 to +150 °C |
| Thermal Resistance — Junction to Case | 5 °C/W |
The BUD42D is available in Case 369-07 for Insertion Mode and Case 369A-13 for Surface Mount Mode.
The typical DC current gain (hFE) is 13 under these conditions.
The maximum lead temperature for soldering is 260 °C.
