BT151 SCR TRIAC Thyristor Datasheet

A Thyristor is a solid-state semiconductor device with four alternating N and P-type material layers. They act as bistable switches, conducting when their gate receives a current trigger, and continue to work while they are forward biased. Thyristors are synonymous with Silicon-Controlled Rectifier (SCR). https://www.tme.eu/Document/a3f2a732350872eddd8f8a3aa9bbd52d/BT151-500C.pdf Features BT151 Thyristor: • High reliability • High surge current capability • High thermal cycling performance • The average on-state current of 7.5A • Maximum gate trigger current of 15mA • The maximum gate trigger voltage is 1.5V • Holding current is 20mA • RMS on-state current is 12A • Repetitive peak off-state voltage of 800V • Non-repetitive peak on-state current of 120A Specifications BT151 Thyristor: Attribute | Value | Rated Average On-State Current | 7.5A | Thyristor Type | SCR | Package Type | TO-220AB | Repetitive Peak Reverse Voltage | 800V | Surge Current Rating | 132A | Mounting Type | Through Hole | Maximum Gate Trigger Current | 15mA | Maximum Gate Trigger Voltage | 1.5V | Maximum Holding Current | 20mA | Pin Count | 3 | Length | 10.3mm | Width | 4.7mm | Height | 9.4mm | Dimensions | 10.3 x 4.7 x 9.4mm | Repetitive Peak Forward Blocking Voltage | 800V | Maximum Operating Temperature | +125 °C | Peak On-State Voltage | 1.75V | Repetitive Peak Off-State Current | 0.5mA | Minimum Operating Temperature | -40 °C | Package Includes: 1 x WeEn Semiconductors Co., Ltd, BT151-800R, Thyristor, 800V 7.5A, 15mA 3-Pin, TO-220AB
