Product details
Overview
BCR12CM-12LB#BB0 from Renesas Electronics is a 600V, 12A non-insulated planar passivated triac designed for medium-power AC phase control in industrial and consumer systems. It delivers 12 A RMS on-state current at Tc = 123°C, supports 720 V non-repetitive peak off-state voltage, and operates up to 150°C junction temperature - enabling robust motor and heater control in compact TO-220ABS packages.
For engineers reviewing the BCR12CM-12LB#BB0 datasheet, BCR12CM-12LB#BB0 pinout, BCR12CM-12LB#BB0 application, or BCR12CM-12LB#BB0 equivalent, key selection criteria include gate trigger sensitivity (≤30 mA), critical dv/dt immunity (10 V/μs at 125°C), thermal resistance (1.8 °C/W j-c), and compatibility with resistive/inductive AC loads requiring zero-crossing or phase-angle control.
Technical Context
This triac operates in all four quadrants with verified gate trigger characteristics across I, II, and III modes - each requiring ≤30 mA gate current and ≤1.5 V gate voltage at 25°C. Its planar passivation structure ensures stable blocking performance up to 600 V repetitive peak off-state voltage (VDRM) and low leakage (≤2.0 mA IDRM at 150°C).
Thermal design is enabled by a 1.8 °C/W junction-to-case thermal resistance and validated commutation behavior: it sustains 120 A surge current for one 60 Hz cycle and maintains reliable turn-off under inductive load conditions with di/dt = –6.0 A/ms and dv/dt up to 10 V/μs at 125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 600 V - Ensures reliable blocking of standard 230 VAC mains with ≥2.6× safety margin |
| IT(RMS) | 12 A - Supports continuous conduction at full sine-wave 360° for motor or heater loads |
| Tj max | +150°C - Enables operation in high-ambient industrial enclosures without derating |
| Rth(j-c) | 1.8 °C/W - Allows direct mounting to heatsinks for efficient thermal management |
| (dv/dt)c | 10 V/μs at 125°C - Prevents false triggering in noisy inductive switching environments |
| IGT | ≤30 mA - Compatible with low-power microcontroller GPIO or optocoupler drivers |
| VTM | ≤1.6 V at 20 A - Limits conduction loss to <32 W at full load, reducing heatsink requirements |
Pinout & Package
BCR12CM-12LB#BB0 uses the TO-220ABS package (Renesas code PRSS0004AG-A), featuring a non-insulated metal tab (T2) for direct heatsink mounting and standardized lead spacing compatible with manual or automated through-hole assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (T1) | Main Terminal 1 | AC line input or load return path - carries full load current in either direction |
| 2 (T2) | Main Terminal 2 | Common connection point and electrically exposed metal tab - must be isolated from chassis unless referenced to neutral |
| 3 (Gate) | Control Input | Triggers conduction when pulsed with ≥30 mA; polarity-sensitive per quadrant (I/II/III) |
| 4 (T2) | Main Terminal 2 (duplicate) | Second physical connection to same T2 node - improves current sharing and mechanical stability |
Key Features
| Feature | Design Value |
|---|---|
| Planar passivation | Ensures long-term VDRM stability and reduced surface leakage under humid or contaminated conditions |
| Non-insulated TO-220ABS | Enables low-thermal-resistance mounting while minimizing bill-of-materials cost vs. insulated variants |
| Quadrant III gate sensitivity | Guarantees reliable turn-on with negative gate pulses - essential for snubberless inductive load control |
| 120 A single-cycle surge rating | Withstands motor startup inrush and solenoid energization without failure |
| 1.8 °C/W Rth(j-c) | Permits use of compact heatsinks in space-constrained power modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac-based AC control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BTB12-600BW | Same 12 A/600 V rating; higher IGT (≤50 mA); TO-220AB package with insulated tab | Requires isolation between heatsink and circuit ground; less sensitive gate drive | Select when electrical isolation from heatsink is mandatory and gate drive strength exceeds 50 mA |
| ON Semiconductor MAC12N6G | 12 A/600 V; lower thermal resistance (1.5 °C/W); no quadrant III gate spec confirmed | Better thermal performance but unverified commutation robustness in inductive loads | Select when thermal budget is tight and load is primarily resistive or lightly inductive |
Compared with BTB12-600BW and MAC12N6G, BCR12CM-12LB#BB0 offers verified quadrant III gate sensitivity and documented 10 V/μs dv/dt immunity at 125°C - making it preferable for snubberless inductive control where gate drive headroom and noise immunity are constrained.

FAQ
What is the maximum junction temperature rating for BCR12CM-12LB#BB0?
The BCR12CM-12LB#BB0 has a maximum junction temperature (Tj) rating of +150°C, as specified in its Absolute Maximum Ratings table. This allows sustained operation in high-ambient environments such as enclosed motor drives or industrial heating cabinets. Derating curves in the datasheet confirm usable RMS current down to 0 A at 150°C ambient when mounted on a properly sized heatsink. The BCR12CM-12LB#BB0 must not exceed this limit to ensure reliability and prevent parametric shift or catastrophic failure.
Does BCR12CM-12LB#BB0 support all four quadrants of triac operation?
Yes, the BCR12CM-12LB#BB0 supports triggering in Quadrants I, II, and III - with fully characterized gate trigger voltage (≤1.5 V) and current (≤30 mA) for each. Quadrant IV operation is not explicitly tested or guaranteed per the datasheet. The device's planar passivation and symmetric structure enable bidirectional conduction, but design-in should follow the validated I/II/III gate drive waveforms shown in the Gate Trigger Characteristics Test Circuits section. For BCR12CM-12LB#BB0, Quadrant III operation is especially emphasized for inductive load commutation.
What is the thermal resistance from junction to case for BCR12CM-12LB#BB0?
The junction-to-case thermal resistance (Rth(j-c)) for BCR12CM-12LB#BB0 is 1.8 °C/W, measured under standard test conditions with case temperature taken at the T2 tab 1.5 mm from the molded case. This value assumes direct metal-to-metal contact with a greased heatsink; actual system-level thermal performance depends on interface material, mounting pressure, and heatsink geometry. The BCR12CM-12LB#BB0 datasheet also specifies Rth(c-f) = 1.0 °C/W for greased aluminum fins, enabling accurate thermal modeling in power module designs.
Is BCR12CM-12LB#BB0 RoHS compliant and lead-free?
Yes, BCR12CM-12LB#BB0 is RoHS compliant and lead-free, consistent with Renesas Electronics' environmental policy and the "General Notes for Handling and Using Semiconductor Devices" referenced in the datasheet. The device meets EU Directive 2011/65/EU (RoHS 2) requirements, with lead content below 0.1 wt% in homogeneous materials. Packaging markings and ordering codes (e.g., #BB0) align with Renesas' standard lead-free qualification process. Always verify latest compliance status via Renesas' official product page or material declaration before high-volume production of BCR12CM-12LB#BB0.
What does the #BB0 suffix indicate in BCR12CM-12LB#BB0?
The #BB0 suffix in BCR12CM-12LB#BB0 denotes the TO-220ABS package variant (Renesas code PRSS0004AG-A) supplied in 50-piece tubes, designated as an EOL Candidate per the Ordering Information table. It distinguishes this version from #BH0 (TO-220ABA, mass production). The #BB0 variant features a straight lead form and shares identical electrical specifications with other BCR12CM-12LB variants - including 12 A RMS current, 600 V VDRM, and ≤30 mA gate trigger current. BCR12CM-12LB#BB0 remains functional and supported for legacy design continuity.
