This document describes the features and characteristics of ROHM's 100mA/50V digital transistors (with built-in resistors) DTC024EM / DTC024EEB / DTC024EUB.
The DTC024 series are NPN epitaxial planar silicon transistors with built‑in thin‑film bias resistors. The integrated resistors allow inverter circuits without external input resistors and reduce parasitic effects.
Typical applications include inverters, interfaces, and drivers. The devices are supplied in VMT3, EMT3F, and UMT3F tape‑and‑reel packages, with detailed electrical characteristics such as a 50 V supply rating, 100 mA collector current, and up to 250 MHz transition frequency.
| Supply voltage | 50 V |
|---|---|
| Input voltage | 40 V |
| Collector current | 100 mA |
| Output current | 30 mA |
| Power dissipation | 150‑200 mW |
| Junction temperature | 150 °C |
| Storage temperature range | -55 °C to +150 °C |
| Input resistance (typ.) | 22 kΩ |
| Transition frequency | 250 MHz |
They are intended for inverter, interface, and driver circuits.
The built‑in bias resistors allow an inverter circuit to be configured without external input resistors.
