PEMH1 and PUMH1 are NPN/NPN transistors produced by PHILIPS, with built-in bias resistors, which can simplify circuit design, reduce component count and costs.
The Philips PEMH1 and PUMH1 are NPN/NPN resistor-equipped transistors featuring built-in bias resistors (R1=22 kΩ, R2=22 kΩ). These components are designed to simplify circuit design and reduce component count, making them suitable for low current peripheral drivers and digital applications where they can replace general-purpose transistors or control IC inputs.
The document details the electrical characteristics, including a maximum collector-emitter voltage of 50 V and an output current of 100 mA. It also specifies two available plastic surface-mounted packages: SOT666 (6 leads) and SOT363 (SC-88), providing thermal resistance data and pin configurations for each.
| Collector-emitter voltage (VCEO) | -50 V |
|---|---|
| Output current (IO) | -100 mA |
| Bias resistor R1 | 22 kΩ |
| Bias resistor R2 | 22 kΩ |
| Total power dissipation (SOT363) | 300 mW |
| Total power dissipation (SOT666) | 300 mW |
| DC current gain (hFE) | 60 |
They are used as low current peripheral drivers, replacements for general purpose transistors in digital applications, and for controlling IC inputs.
The devices are available in two plastic surface mounted packages: SOT666 (6 leads) and SOT363 (SC-88).
