Product details
Overview
BCR20CM-16LB#BB0 from Renesas Electronics is a non-insulated, planar passivated 800 V, 20 A triac designed for medium-power AC phase-control applications. It delivers RMS on-state current of 20 A at Tc = 116°C, supports 200 A non-repetitive surge current, and operates up to 150°C junction temperature - enabling robust motor control, heater regulation, and power supply switching in industrial and appliance systems.
For engineers reviewing the BCR20CM-16LB#BB0 datasheet, BCR20CM-16LB#BB0 pinout, BCR20CM-16LB#BB0 application, or BCR20CM-16LB#BB0 equivalent, key selection criteria include repetitive peak off-state voltage (800 V), gate trigger current (30 mA), thermal resistance (1.4 °C/W j-c), and TO-220ABS package compatibility with heatsink mounting.
Technical Context
This triac operates in all four quadrants (I, II, III, IV) with symmetrical gate trigger characteristics across I and III quadrants. Its planar passivation structure ensures stable dv/dt immunity - 10 V/μs at Tj = 125°C and 1 V/μs at Tj = 150°C - critical for reliable commutation in inductive loads like motors and transformers.
It features low on-state voltage (≤1.5 V at 30 A), tight gate trigger voltage tolerance (≤1.5 V), and defined latching/holding currents validated across –40°C to +150°C. The device uses standard triac triggering circuitry with 330 Ω gate resistor and 6 Ω load per test procedures I–III.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 800 V - blocks full AC mains cycles up to 800 V peak without conduction, suitable for 230 VAC and 400 VAC industrial systems. |
| IT(RMS) | 20 A - delivers continuous sinusoidal AC current at 116°C case temperature, supporting 2.4 kW resistive load at 120 VAC. |
| ITSM | 200 A - withstands single-cycle 60 Hz surge, enabling robust startup handling for compressors and pumps. |
| Rth(j-c) | 1.4 °C/W - enables efficient heat transfer to heatsink; requires ≤28 W dissipation margin for 20 A conduction at 150°C max junction temp. |
| IFGTI / IRGTI / IRGTIII | 30 mA - consistent gate trigger current across quadrants, simplifying driver design with standard optotriac couplers (e.g., MOC3041). |
| (dv/dt)c | 10 V/μs @ 125°C - prevents false turn-on during fast voltage transients in noisy industrial environments. |
| VTM | ≤1.5 V @ 30 A - minimizes conduction loss (≤45 W at 30 A), reducing thermal stress and heatsink size requirements. |
Pinout & Package
BCR20CM-16LB#BB0 is housed in a TO-220ABS package (Renesas code PRSS0004AG-A), featuring a non-insulated metal tab (T2) for direct heatsink mounting. The package includes three terminals: T1, T2 (dual tab connection), and Gate - optimized for high-current AC switching with low thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| T1 | Anode 1 / Main Terminal 1 | Primary current path input; connects to AC line or load side depending on circuit topology (e.g., T1 to load in high-side switch). |
| T2 | Anode 2 / Main Terminal 2 | Common return path and mechanical heatsink interface; electrically connected to metal tab - must be isolated from chassis if insulation required. |
| Gate | Control terminal | Triggers conduction when ≥30 mA pulse applied; polarity-sensitive for quadrant-specific firing (e.g., G–/T2+ for Quadrant I). |
Key Features
| Feature | Design Value |
|---|---|
| Planar passivation | Ensures long-term stability of blocking voltage and dv/dt immunity under thermal cycling and humidity stress. |
| Quadrant I & III symmetry | Enables simplified zero-crossing or phase-angle control using single optocoupler configuration without polarity switching. |
| 150°C max junction temperature | Supports operation in sealed enclosures or high-ambient environments (e.g., HVAC control boards) without derating below 20 A. |
| Non-insulated TO-220ABS | Reduces thermal interface resistance vs insulated packages; requires external isolation if safety standards mandate reinforced insulation. |
| 1.4 °C/W junction-to-case | Allows use with compact extruded or stamped heatsinks - e.g., 50 mm × 50 mm × 25 mm finned aluminum achieves <70°C case rise at 20 A. |
Applications
| Motor Speed Control | Heater Power Regulation |
|---|---|
Use Scenario: Variable-speed control of universal motors in power tools and kitchen appliances using phase-angle firing.

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 BTB20-800CW | Same 20 A/800 V rating; insulated TO-220 package (VISO = 2500 VRMS); higher Rth(j-c) = 1.7 °C/W. | Eliminates need for insulating washer but increases thermal resistance - requires larger heatsink for same 20 A load. | Select when reinforced insulation is mandated by IEC 60335 or UL 60730; avoid if thermal budget is tight. |
| ON Semiconductor MAC20M8G | 20 A/800 V; TO-220AB package; lower (dv/dt)c = 6 V/μs @ 125°C; gate trigger current 50 mA (higher drive requirement). | Less immune to voltage transients; needs stronger gate driver - unsuitable for noisy motor-drive environments. | Select only for cost-sensitive, low-noise applications (e.g., basic lamp dimmers); verify dv/dt margin in final layout. |
Compared with BTB20-800CW and MAC20M8G, BCR20CM-16LB#BB0 offers superior dv/dt immunity and lower thermal resistance in a non-insulated TO-220ABS package - making it optimal for thermally constrained, high-noise industrial controls where external isolation is already implemented.

FAQ
What is the maximum allowable case temperature for continuous 20 A operation of BCR20CM-16LB#BB0?
The BCR20CM-16LB#BB0 supports 20 A RMS continuous conduction at a case temperature (Tc) of 116°C, as specified in the Maximum Ratings table. Exceeding this temperature requires current derating per the "Allowable Case Temperature vs. RMS On-State Current" curve on page 4 of the datasheet. Operation above 116°C risks exceeding the 150°C junction limit even with ideal heatsinking.
Does BCR20CM-16LB#BB0 require a heatsink for 20 A operation?
Yes - BCR20CM-16LB#BB0 requires a heatsink for 20 A RMS operation. With Rth(j-c) = 1.4 °C/W and max Tj = 150°C, even at ambient 40°C, the heatsink-to-ambient thermal resistance must be ≤32.9 °C/W to maintain safe junction temperature. A typical 50 mm × 50 mm × 25 mm aluminum heatsink meets this requirement under natural convection.
Is BCR20CM-16LB#BB0 compatible with zero-crossing optotriacs like MOC3041?
Yes - BCR20CM-16LB#BB0 is fully compatible with zero-crossing optotriacs such as the MOC3041. Its 30 mA gate trigger current (IFGTI) falls within the MOC3041's 100 mA peak output capability, and its 1.5 V gate trigger voltage matches the optocoupler's typical forward voltage drop. No external gate resistor is needed beyond the MOC3041's internal 330 Ω.
What is the difference between BCR20CM-16LB#BB0 and BCR20CM-16LB#BH0?
BCR20CM-16LB#BB0 uses the TO-220ABS package (Renesas code PRSS0004AG-A), while BCR20CM-16LB#BH0 uses TO-220ABA (PRSS0004AT-A). The ABS variant has a shorter body (15.7 mm vs. 18.95 mm) and different lead spacing - making them mechanically non-interchangeable despite identical electrical specs. #BB0 is marked EOL announced per the Ordering Information table on page 8.
Can BCR20CM-16LB#BB0 be used in DC applications?
No - BCR20CM-16LB#BB0 is a triac designed exclusively for AC operation. It cannot block DC voltage after turn-on and will remain latched until current falls below the holding current (typically ~50 mA). For DC switching, a MOSFET or IGBT solution is required. Using BCR20CM-16LB#BB0 in DC circuits risks destructive latch-up and device failure.
