Renesas BCR16KM-12LA-1#B00

Overview

BCR16KM-12LA-1#B00 from Renesas Electronics is a non-insulated planar passivated triac rated for 16 A RMS on-state current and 600 V repetitive peak off-state voltage, designed for medium-power AC switching in household appliances and industrial controls. It features gate trigger currents of ≤30 mA across all quadrants (I, II, III), 1.5 V maximum on-state voltage at 25 A, and a critical commutating dv/dt rating of 10 V/µs at 125°C.

For engineers reviewing the BCR16KM-12LA-1#B00 datasheet, BCR16KM-12LA-1#B00 pinout, BCR16KM-12LA-1#B00 application, or BCR16KM-12LA-1#B00 equivalent, this device serves as a robust, TO-220 packaged AC power switch requiring precise gate drive timing, thermal management at Tc = 100°C, and compatibility with resistive/inductive loads in phase-control and zero-crossing configurations.

Technical Context

The BCR16KM-12LA-1#B00 operates as a bidirectional thyristor with four-quadrant gate triggering capability, supporting both I- and III-quadrant triggering per JEDEC SC-46/TO-220 outline. Its planar passivation structure ensures stable blocking characteristics up to 720 V non-repetitive peak off-state voltage and low leakage (≤2.0 mA IDRM at 125°C).

Thermal performance is defined by a junction-to-case thermal resistance of 1.4 °C/W, enabling 16 A RMS conduction at 100°C case temperature with appropriate heatsinking. The device sustains surge on-state current up to 170 A (60 Hz, 1-cycle) and exhibits latching and holding behavior validated across –40°C to +125°C junction temperature range.

Key Specifications

Pinout & Package

FAQ

What is the maximum junction temperature specification for BCR16KM-12LA-1#B00?

The BCR16KM-12LA-1#B00 has a specified junction temperature range of –40°C to +125°C. This allows operation in demanding environments such as enclosed appliance cabinets or industrial control panels. Derating of RMS current is required above Tc = 100°C, and thermal design must ensure Rth(j-c) = 1.4 °C/W is maintained with proper heatsinking and thermal interface material.

Does BCR16KM-12LA-1#B00 support all four triggering quadrants?

Yes, BCR16KM-12LA-1#B00 supports gate triggering in Quadrants I, II, and III with guaranteed gate trigger current ≤30 mA under standard test conditions (VD = 6 V, RL = 6 Ω, RG = 330 Ω, Tj = 25°C). Quadrant IV triggering is not characterized in the official datasheet and should not be relied upon in production designs.

Is BCR16KM-12LA-1#B00 insulated or non-insulated?

BCR16KM-12LA-1#B00 is a non-insulated triac: its metal tab (T2 terminal) is electrically connected to the T2 semiconductor terminal. This requires mechanical isolation (e.g., mica washer + thermal grease) if mounting to a grounded heatsink. Insulated alternatives like ST's BTB16-600BW require no such isolation but exhibit higher thermal resistance.

What is the surge current rating of BCR16KM-12LA-1#B00 and how is it tested?

The BCR16KM-12LA-1#B00 has a non-repetitive surge on-state current (ITSM) rating of 170 A, measured as the peak value of a single 60 Hz sine-wave half-cycle. This rating validates its ability to handle inrush currents from cold filaments, motor windings, or transformer primaries without latch-up or thermal runaway, provided case temperature remains within limits.

Can BCR16KM-12LA-1#B00 be used with zero-crossing detection circuits?

Yes, BCR16KM-12LA-1#B00 is compatible with zero-crossing detection circuits when paired with an appropriate zero-crossing optocoupler (e.g., MOC3041). Its low gate trigger current (≤30 mA) and stable turn-on characteristics at low dV/dt make it well-suited for noise-immune, low-EMI switching in heating and fan control applications where precise timing relative to AC zero crossings is required.
