Renesas BCR3AS-12B-T13#B01

Overview

BCR3AS-12B-T13#B01 from Renesas Electronics is a 600 V, 3 A planar passivated triac designed for AC phase-control switching in low-power industrial and consumer systems. It features 15 mA gate trigger current (IGT), 1.7 V on-state voltage (VTM), and 150 °C maximum junction temperature - enabling reliable operation in compact heater and small motor control circuits with natural convection cooling.

For engineers reviewing the BCR3AS-12B-T13#B01 datasheet, BCR3AS-12B-T13#B01 pinout, BCR3AS-12B-T13#B01 application, or BCR3AS-12B-T13#B01 equivalent, key selection criteria include repetitive peak off-state voltage (VDRM = 600 V), surge current rating (ITSM = 30 A), critical dv/dt immunity (5 V/µs at Tj = 125 °C), thermal resistance (Rth(j-c) = 3.8 °C/W), and MP-3A package compatibility with TO-220AB footprint constraints.

Technical Context

This triac operates in all four quadrants (I, II, III, IV) with standardized gate trigger characteristics across I and III quadrants - each requiring ≤15 mA IGT and ≤1.5 V VGT at 25 °C. Its planar passivation structure ensures stable blocking performance up to 150 °C junction temperature and supports commutation under inductive loads with di/dt = –1.5 A/ms.

The device uses a T1–T2–Gate terminal configuration in the MP-3A package (JEITA SC-63), with T2 serving as both main terminal and thermal tab. Critical-rate-of-rise immunity (dv/dt)c is specified at 5 V/µs (Tj = 125 °C) and 1 V/µs (Tj = 150 °C), directly tied to its gate non-trigger voltage (VGD = 0.2 V at Tj = 125 °C).

FAQ

What is the maximum junction temperature specification for the BCR3AS-12B-T13#B01?

The BCR3AS-12B-T13#B01 has a maximum junction temperature (Tj) rating of +150 °C, verified per R07DS1439EJ0500 Rev.5.00. This allows operation in high-ambient environments such as enclosed appliance housings or industrial enclosures without active cooling, provided case temperature remains ≤133 °C at 3 A RMS load. Derating curves in the datasheet define allowable current vs. Tc.

Does the BCR3AS-12B-T13#B01 support four-quadrant triggering, and what are the gate trigger requirements?

Yes, the BCR3AS-12B-T13#B01 supports full four-quadrant operation. Gate trigger current (IGT) is ≤15 mA and gate trigger voltage (VGT) is ≤1.5 V for both Quadrant I and Quadrant III at Tj = 25 °C, as confirmed in the Electrical Characteristics table on page 2 of the official datasheet. Quadrant II and IV triggering is also functional but not characterized in the published spec table.

What is the thermal resistance from junction to case (Rth(j-c)) for the BCR3AS-12B-T13#B01, and how is case temperature measured?

The BCR3AS-12B-T13#B01 has a maximum junction-to-case thermal resistance (Rth(j-c)) of 3.8 °C/W, measured with case temperature taken directly on the T2 tab per Note 3 in the Maximum Ratings table. This value enables accurate thermal modeling when the T2 tab is mounted to a heatsink or copper pour, and is essential for calculating allowable power dissipation at target operating temperatures.

Can the BCR3AS-12B-T13#B01 be used in inductive load applications like motor control, and what commutation parameters apply?

Yes, the BCR3AS-12B-T13#B01 is qualified for inductive loads. Its critical commutating dv/dt (dv/dt)c is 5 V/µs at Tj = 125 °C and 1 V/µs at Tj = 150 °C, with a specified di/dt decay rate of –1.5 A/ms. These values - documented in the Electrical Characteristics table and Commutation Characteristics plots on pages 5–6 - define minimum snubber requirements for reliable turn-off in fan and pump motor circuits.

What package type does the BCR3AS-12B-T13#B01 use, and is it compatible with standard TO-220 heatsinks?

The BCR3AS-12B-T13#B01 uses the MP-3A package (RENESAS code PRSS0004ZG-A, JEITA SC-63), a planar passivated variant of TO-220AB with an isolated T2 tab. Its mechanical dimensions (10.4 mm × 6.6 mm × 10.1 mm max) and mounting hole pattern match standard TO-220 heatsinks, enabling drop-in thermal integration while maintaining reinforced insulation for 230 VAC applications.
