Product details
Overview
BCR20CM-12LB#BB0 from Renesas Electronics is a medium-power, non-insulated planar passivated triac rated for 20 A RMS on-state current and 600 V repetitive peak off-state voltage, with gate trigger current ≤30 mA (Quadrants I, II, III), designed for AC phase-control in motor-driven and resistive heating loads.
For engineers reviewing the BCR20CM-12LB#BB0 datasheet, BCR20CM-12LB#BB0 pinout, BCR20CM-12LB#BB0 application, or BCR20CM-12LB#BB0 equivalent, this device supports reliable zero-crossing–free switching in compact TO-220 packages where thermal management at Tc = 109°C and dv/dt immunity ≥10 V/µs are critical design requirements.
Technical Context
This triac operates in all four quadrants but specifies gate trigger parameters only for Quadrants I, II, and III per test conditions (VD = 6 V, RL = 6 Ω, RG = 330 Ω). It features a junction-to-case thermal resistance of 0.8°C/W and supports surge on-state current up to 200 A (60 Hz, 1-cycle sine peak).
Its commutation capability is characterized at Tj = 125°C with critical dv/dtc ≥10 V/µs and di/dtc = –10 A/ms under inductive load conditions, enabling stable operation in heater and motor controller circuits without external snubbers in many cases.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RMS On-State Current | 20 A - Sustains continuous conduction at full sine wave, 360°, with case temperature ≤109°C |
| Repetitive Peak Off-State Voltage | 600 V - Blocks line voltage surges up to 600 V in AC mains applications (e.g., 230 VAC systems) |
| Gate Trigger Current (IGT) | ≤30 mA - Low drive requirement compatible with microcontroller GPIO or optocoupler outputs |
| Critical dv/dt (commutating) | ≥10 V/µs - Resists false turn-on during rapid voltage transients in inductive load switching |
| Junction-to-Case Thermal Resistance | 0.8°C/W - Enables efficient heat transfer to heatsink; requires thermal interface material for optimal performance |
| Surge On-State Current | 200 A - Withstands short-duration inrush currents (e.g., cold filament lamps, motor startup) |
| On-State Voltage | ≤1.5 V - Limits conduction loss to <30 W at 20 A, reducing thermal stress in high-duty-cycle operation |
Pinout & Package
BCR20CM-12LB#BB0 uses the TO-220 package (RENESAS code PRSS0004AA-A), with metal tab (T2) serving as both terminal and thermal path. The device is non-insulated: the tab is electrically connected to T2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| T1 | Main Terminal 1 | Anode-side main current path; connects to load return or neutral in AC circuits |
| T2 | Main Terminal 2 | Cathode-side main current path; electrically tied to metal tab and heatsink |
| Gate | Control Input | Triggers conduction when forward-biased relative to T2; polarity-sensitive per quadrant |
Key Features
| Feature | Design Value |
|---|---|
| Planar Passivation Structure | Enhances long-term reliability and moisture resistance in industrial environments |
| Non-Insulated TO-220 Package | Reduces thermal impedance vs. insulated variants, enabling higher power density with direct heatsink mounting |
| Quadrant I/II/III Gate Sensitivity | Ensures robust triggering across common AC phase-control configurations without requiring negative gate drive circuitry |
| 167 A²s I²t Rating | Defines fusing limit for short-circuit protection coordination with fast-acting fuses |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac-based AC power control 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) | Requires isolation between heatsink and circuit ground; suited for safety-critical or floating-ground designs | Select when electrical isolation from heatsink is mandatory; accept higher gate drive demand |
| ON Semiconductor MAC20M | 20 A/600 V; non-insulated TO-220; IGT ≤50 mA; lower dv/dtc (8 V/µs) | Reduced commutation robustness in highly inductive loads; may require snubber network | Choose for cost-sensitive, low-dv/dt applications where thermal coupling to heatsink is acceptable |
Compared with BCR20CM-12LB#BB0, BTB20-600B adds insulation at the cost of higher gate drive and reduced thermal efficiency, while MAC20M trades dv/dt immunity for broader availability-neither is pin-compatible, and layout adaptation is required for either replacement.

FAQ
What is the maximum allowable case temperature for continuous operation of BCR20CM-12LB#BB0?
The BCR20CM-12LB#BB0 is rated for continuous RMS on-state current of 20 A at a case temperature (Tc) of 109°C, measured 1.5 mm from the molded case on the T2 tab. Exceeding this temperature reduces current capacity and risks thermal runaway; proper heatsinking and thermal interface material are essential to maintain Tc ≤109°C under full load. Derating curves in the BCR20CM-12LB#BB0 datasheet define allowable current at lower case temperatures.
Does BCR20CM-12LB#BB0 support triggering in all four quadrants?
The BCR20CM-12LB#BB0 datasheet specifies gate trigger voltage and current only for Quadrants I, II, and III under defined test conditions (VD = 6 V, RL = 6 Ω, RG = 330 Ω); no guaranteed triggering performance is provided for Quadrant IV. For reliable four-quadrant operation, consult Renesas' official documentation for BCR20CM-12LB#BB0 or consider explicitly rated alternatives.
Can BCR20CM-12LB#BB0 be used without a heatsink in low-duty-cycle applications?
BCR20CM-12LB#BB0 has a junction-to-case thermal resistance of 0.8°C/W but no specified junction-to-ambient value for unmounted use. In low-duty-cycle or pulsed operation below 5 A RMS, limited self-heating may permit short-term operation without a heatsink; however, sustained conduction-even at reduced current-requires heatsinking to prevent exceeding the 125°C maximum junction temperature. Thermal simulation using BCR20CM-12LB#BB0's transient impedance curves is recommended.
What is the gate non-trigger voltage specification for BCR20CM-12LB#BB0?
The BCR20CM-12LB#BB0 gate non-trigger voltage (VGD) is specified as 0.2 V minimum at Tj = 125°C and VD = ½ VDRM (300 V), ensuring immunity against false triggering from leakage or noise on the gate terminal during high-temperature, high-voltage blocking conditions. This parameter is critical for stable operation in noisy industrial environments where the BCR20CM-12LB#BB0 is deployed.
Is BCR20CM-12LB#BB0 RoHS compliant and lead-free?
Yes, BCR20CM-12LB#BB0 conforms to EU RoHS Directive requirements and is lead-free. Renesas Electronics confirms RoHS compliance for this part in its official environmental documentation; the TO-220 package uses matte tin plating on leads and meets JEDEC J-STD-609A Class 1 marking standards. Full compliance data, including substance declarations, is available through Renesas' website or authorized distributor portals for BCR20CM-12LB#BB0.
