ROHM EMZ1 UMZ1N IMZ1A Data Handbook/Specifications Sheet
Summary
This datasheet covers the ROHM EMZ1, UMZ1N, and IMZ1A dual transistors, each integrating one 2SA1037AK PNP chip and one 2SC2412K NPN chip in a single compact package. The EMZ1 uses EMT6, UMZ1N uses UMT6 (SC-88), and IMZ1A uses SMT6 (SC-74) surface mount packages, all compatible with automatic mounting machines. Absolute maximum ratings include collector-base voltage of ±60V, collector-emitter voltage of ±50V, collector current of ±150mA, and total power dissipation of 150mW for EMT/UMT or 300mW

Frequently Asked Questions
What is the maximum dissipation allowed for the transistors?
The junction temperature (Tj) specification indicates that 200mW per element must not be exceeded (where applicable).
Are there specific compatibility concerns or use limitations?
These products are intended for ordinary electronic equipment but should not be used in safety-critical applications like medical instruments or aerospace machinery without consulting a sales representative.
What is the device's general current handling capability?
The collector current (IC) ratings are generally specified between 150mA and 300mA total, depending on the specific model (EMZ1/UMZ1N vs IMZ1A).
How reliable are these components for specialized equipment?
Users must consult with a sales representative if the product is intended for extremely high-reliability applications where malfunction could endanger human life.
