  1. TO-92 package
  2. TO-126 package

1.TO-92 Package

The TO-92 is a type of package used at 13003 transistors, they are made with plastic and epoxy material, due to this reason they are less expensive and compactable at smaller circuits.

For this TO-92 type package, the pinout details as follow,

  1. Base (b) – Pin01
  2. Collector (c) – Pin02
  3. Emitter (e) – Pin03

This particular transistor version is a low power handling type, which is using TO-92.

2.TO-126 Package

The TO-126 is another type of package used at 13003 transistors, they are made with plastic and epoxy, but the width and length of this type are greater, so this is capable of higher specifications.

For this TO-126 type package, the pinout details are different as follows.

  1. Emitter (e) – Pin01
  2. Collector (c) – Pin02
  3. Base (b) – Pin03

This version of the transistor had high voltage and power capacity, due to this reason TO-126 package is available.


For the 13003 transistors other than TO-92 and TO-126 package, many more packages are available for different circuit applications.

Voltage ratings of 13003

  • Max collector – emitter = 400v
  • Max collector – base voltage = 700v
  • Max emitter – base voltage = 9v

The collector-to-emitter voltage rating is 400v and collector to base voltage rating is 700v, these voltage ratings will make it ideal to use in a wide variety of AC and DC high voltage circuit applications.

The maximum emitter to base voltage is 9v, this is the maximum biasing voltage for this transistor.

Current rating of 13003

  • Maximum collector current = 1.5A
  • Forward current transfer ratio or dc gain = 14 to 57 Hfe
  • Collector peak current = 3A

The maximum collector current is 1.5A, this value shows the maximum current load capacity of 13003 transistors.

The DC gain of transistors is 14 to 57 hfe, this amplification factor is low compare to other transistor types.

Power dissipation

The power dissipation of the 13003 transistor is different due to different package types, for TO-126 power dissipation is 40w and for TO92 the value will be 1.1w.

Maximum storage and operating temperature = -65 to +150˚C

Transition frequency = 10MHz

Storage time = 1us

Fall time = 0.7 us
