Digital Transistor Characteristics Apparatus
Product Code : SCL-PLE-11844
Quick Answer: The Digital Transistor Characteristics Apparatus measures NPN and PNP transistors in common emitter and common base modes on four 3.5-digit digital meters that show input voltage, input current, output voltage and output current together.
Last updated: 18 October 2026
Key Features
- Sockets for both NPN and PNP transistors.
- Common emitter or common base mode chosen with a switch.
- Two independent stabilised DC supplies: 0–1 V for the base and 0–10 V for the collector.
- Four 3.5-digit meters read all four parameters at once, with no parallax error.
- Base current in microamperes and collector current in milliamperes.
- 4 mm safety-shrouded sockets on a printed circuit mimic.
Technical Specifications
| Specification | Value |

How It Is Used
This transistor characteristics kit is used like the analogue version, but all four readings appear at once on digital displays. Students vary the base supply to obtain the input curve, then fix the base current and vary the collector supply to obtain the output curves, for NPN and PNP devices in either configuration.
Frequently Asked Questions
How does the Digital Transistor Characteristics Apparatus differ from an analogue model?
Its four 3.5-digit digital meters show input voltage, input current, output voltage and output current at the same time, avoiding the parallax error of pointer meters.
What ranges do the meters on the Digital Transistor Characteristics Apparatus cover?
The voltmeters read 0–2 V base-emitter and 0–20 V collector-emitter; base current is read in µA and collector current in mA.
