Product details
Overview
BCR20AM-12LBA6#B01 from Renesas Electronics is a 20 A, 600 V medium-power triac designed for phase-controlled AC power switching in resistive and inductive loads. It features non-insulated TO-220 packaging, 30 mA gate trigger current (IGT), 1.5 V on-state voltage (VTM), and supports full-cycle conduction at Tc = 109°C. It is used in vacuum cleaners, electric heaters, light dimmers, and motor controllers.
For engineers reviewing the BCR20AM-12LBA6#B01 datasheet, BCR20AM-12LBA6#B01 pinout, BCR20AM-12LBA6#B01 application, or BCR20AM-12LBA6#B01 equivalent, this page delivers verified triac specifications, thermal resistance (Rth(j-c) = 0.8°C/W), critical dv/dt rating (10 V/µs), gate trigger characteristics across quadrants I/II/III, and real-world use context for industrial and appliance-grade AC control.
Technical Context
This triac operates in all four quadrants with confirmed gate trigger currents ≤30 mA across I, II, and III modes at Tj = 25°C, VD = 6 V, RL = 6 Ω, and RG = 330 Ω. Its planar passivation structure ensures stable blocking performance up to 600 V repetitive peak off-state voltage (VDRM) and 720 V non-repetitive peak (VDSM), with gate non-trigger voltage (VGD) of 0.2 V at Tj = 125°C.
Thermal design is enabled by a junction-to-case thermal resistance of 0.8°C/W and validated surge capability: 200 A ITSM (60 Hz, 1-cycle sine), 167 A²s I²t rating, and commutation robustness under di/dt = –10 A/ms and dv/dt = 10 V/µs at Tj = 125°C - supporting reliable turn-off in inductive motor and heater loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 600 V - Sustains repetitive AC line peaks up to 424 V RMS without conduction. |
| IT(RMS) | 20 A - Continuous RMS current handling at case temperature 109°C with full 360° conduction. |
| IGT (I/II/III) | ≤30 mA - Low gate drive requirement enables direct interface with microcontrollers or optocouplers. |
| VTM | ≤1.5 V - Low on-state voltage minimizes conduction losses and heatsink requirements. |
| Rth(j-c) | 0.8 °C/W - Enables thermal management using standard TO-220 heatsinks with known derating curves. |
| (dv/dt)c | 10 V/µs - Minimum critical rate of rise for reliable commutation in inductive loads at 125°C junction. |
| ITSM | 200 A - Withstands short-duration surges (e.g., motor startup) without latch-up or failure. |
Pinout & Package
BCR20AM-12LBA6#B01 uses the non-insulated TO-220 package (RENESAS code PRSS0004AA-A, JEITA SC-46), with metal tab serving as T2 terminal and integral heat transfer path. Mounting requires electrical isolation if circuit ground referencing differs from heatsink potential.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| T1 | Anode 1 / Main Terminal 1 | Primary current path input; connects to AC line or load return depending on configuration. |
| T2 | Anode 2 / Main Terminal 2 | Current path output and thermal interface; metal tab must be mounted to heatsink with insulating washer if isolation required. |
| G | Gate | Control input for triggering; polarity-sensitive per quadrant (I: T2+, G–; II: T2–, G–; III: T2–, G+). |
Key Features
| Feature | Design Value |
|---|---|
| Quadrant I/II/III operation | Enables universal AC phase control without external polarity reversal circuitry. |
| Planar passivation construction | Ensures long-term stability of VDRM and leakage current under thermal cycling and humidity stress. |
| Low IGT (≤30 mA) | Reduces gate driver component count and power consumption in microcontroller-based systems. |
| Non-insulated TO-220 package | Optimizes thermal performance via direct metal tab contact while requiring system-level isolation planning. |
| 167 A²s I²t rating | Provides predictable fuse coordination and surge withstand margin for motor-start transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac-based AC power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BTB20-600B | Same 20 A/600 V rating; insulated TO-220 package; higher IGT (50 mA max); lower Rth(j-c) (0.7°C/W). | Eliminates need for insulating hardware but requires higher gate drive energy. | Select when board-level isolation is preferred over heatsink-level isolation. |
| ON Semiconductor MAC20M | 20 A/600 V; non-insulated TO-220; IGT ≤ 50 mA; higher VTM (≤1.7 V); Rth(j-c) = 0.9°C/W. | Slightly higher conduction loss and thermal resistance; broader availability in high-volume distribution. | Select when supply chain flexibility outweighs marginal thermal or gate drive optimization. |
Compared with BCR20AM-12LBA6#B01, BTB20-600B offers built-in insulation at the cost of gate sensitivity, while MAC20M trades minor efficiency for wider logistics support - making BCR20AM-12LBA6#B01 optimal where low IGT and proven thermal performance in non-isolated mounting are prioritized.

FAQ
What is the maximum junction temperature rating for BCR20AM-12LBA6#B01?
The BCR20AM-12LBA6#B01 has a specified junction temperature range of –40°C to +125°C. This allows operation in demanding environments such as enclosed heater housings or motor control enclosures with limited airflow. Thermal design must ensure that actual junction temperature remains within this limit under worst-case conduction and ambient conditions, using the documented Rth(j-c) = 0.8°C/W and derating curves from the datasheet.
Does BCR20AM-12LBA6#B01 support all four quadrants of triac triggering?
Yes, BCR20AM-12LBA6#B01 supports triggering in Quadrants I, II, and III - confirmed by gate trigger current measurements (IFGTI, IRGTI, IRGTIII ≤ 30 mA) under standardized test conditions. Quadrant IV triggering is not characterized in the official datasheet and should not be assumed functional. Designers must verify quadrant-specific gate polarity and voltage compliance per application circuit topology.
What is the gate trigger voltage specification for BCR20AM-12LBA6#B01?
The gate trigger voltage (VGT) for BCR20AM-12LBA6#B01 is specified as ≤1.5 V across all three tested quadrants (I, II, III) at Tj = 25°C, VD = 6 V, RL = 6 Ω, and RG = 330 Ω. This low threshold ensures compatibility with standard logic-level drivers and optocouplers such as MOC3021 or IL420 without additional level-shifting circuitry.
Can BCR20AM-12LBA6#B01 be used in inductive load applications like motor control?
Yes, BCR20AM-12LBA6#B01 is explicitly rated for inductive loads, with validated commutation performance: (dv/dt)c = 10 V/µs and (di/dt)c = –10 A/ms at Tj = 125°C. Its planar passivation structure and 167 A²s I²t rating provide robust turn-off margin during motor coil energy discharge - essential for vacuum cleaner and copier motor drives.
What is the thermal resistance from junction to case for BCR20AM-12LBA6#B01?
The junction-to-case thermal resistance (Rth(j-c)) of BCR20AM-12LBA6#B01 is 0.8°C/W, measured at the T2 tab 1.5 mm from the molded case. This value enables accurate heatsink sizing using standard TO-220 mounting practices and published derating curves. When greased, the case-to-heatsink resistance adds ~1.0°C/W, defining total thermal path performance.
