BTA201 series B, E and ER
1 A Three-quadrant triacs high commutation
Rev. 04 — 4 February 2008
Product data sheet
1. Product profile
1.1 General description
Passivated, guaranteed commutation triacs in a plastic package. The ‘sensitive gate’ E
and ER series are intended for interfacing with low power drivers, including
microcontrollers. The high commutation B series are designed to commutate the full RMS
current at the maximum junction temperature without the aid of a snubber.
1.2 Features
I Suitable for interfacing with low power
drivers, including microcontrollers
I Reverse pinning option (ER type)
1.3 Applications
I Motor controls
I Solenoid drivers
1.4 Quick reference data
I ITSM ≤ 12.5 A
I IT(RMS) ≤ 1 A
I VDRM ≤ 600 V (BTA201-600B/E)
I VDRM ≤ 800 V (BTA201-800B/E/ER)
I IGT ≤ 50 mA (BTA201-600B/800B)
I IGT ≤ 10 mA (BTA201-600E/800E/ER)
I IGT ≥ 5 mA (BTA201-600B/800B)
I IGT ≥ 1 mA (BTA201-600E/800E/ER)
