Product details
Overview
BCR20FM-12LB#BB0 from Renesas Electronics is a 600 V, 20 A insulated triac in TO-220FP package, designed for medium-power AC phase control in motor and heater circuits. It features 2000 V isolation voltage, 150 °C junction temperature rating, and gate trigger current ≤30 mA across all three quadrants (I/II/III), enabling reliable zero-crossing and non-zero-crossing switching in industrial solid-state relays.
For engineers reviewing the BCR20FM-12LB#BB0 datasheet, BCR20FM-12LB#BB0 pinout, BCR20FM-12LB#BB0 application, or BCR20FM-12LB#BB0 equivalent, this device supports thermally demanding AC load control where galvanic isolation, high dv/dt immunity (10 V/µs at 125 °C), and stable gate triggering under elevated junction temperatures are critical selection criteria.
Technical Context
This triac uses planar passivation technology and an insulated TO-220FP package to achieve 2000 V AC isolation between main terminals (T1/T2/Gate) and case. Its rated RMS on-state current of 20 A is specified at Tc = 104 °C, with thermal resistance Rth(j-c) = 2.3 °C/W - optimized for heatsink-mounted operation in continuous conduction mode.
It supports full-quadrant triggering (I/II/III) with identical gate trigger voltage (≤1.5 V) and current (≤30 mA) specifications, ensuring consistent turn-on behavior across inductive and resistive loads. Critical commutation parameters - including (dv/dt)c = 10 V/µs at 125 °C and (di/dt)c = –10 A/ms - define its robustness against false triggering during AC line transients and inductive load switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 600 V - Maximum repetitive peak off-state voltage; defines maximum AC line voltage it can block safely in steady state. |
| IT(RMS) | 20 A - Continuous RMS on-state current capability at case temperature 104 °C; sets thermal design baseline for heatsink sizing. |
| Viso | 2000 V AC - Isolation voltage between terminals and case for 1 minute; enables safe use in grounded-chassis industrial equipment. |
| Tj max | +150 °C - Maximum allowable junction temperature; determines derating curves and long-term reliability under thermal stress. |
| (dv/dt)c | 10 V/µs at Tj = 125 °C - Minimum critical rate of rise of off-state voltage before unintended turn-on; key for noise immunity in EMI-prone environments. |
| IGT (I/II/III) | ≤30 mA - Gate trigger current for all three operating quadrants; ensures compatibility with standard microcontroller GPIO or optocoupler drivers. |
| Rth(j-c) | 2.3 °C/W - Junction-to-case thermal resistance; directly used to calculate junction temperature rise above heatsink temperature. |
Pinout & Package
BCR20FM-12LB#BB0 is housed in an insulated TO-220FP package (Renesas code PRSS0003AG-A), featuring electrically isolated metal tab for direct heatsink mounting without insulating washers. The case serves as the thermal path only - no electrical connection to internal die.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| T1 | Main Terminal 1 | Anode-side AC line terminal; carries full load current in both half-cycles when triggered. |
| T2 | Main Terminal 2 | Cathode-side AC line terminal; completes conduction path with T1 during triggered conduction. |
| G | Gate | Control input for triggering; accepts low-energy pulse (≤2 A peak, ≤5 W peak power) to initiate conduction in any quadrant. |
Key Features
| Feature | Design Value |
|---|---|
| Insulated TO-220FP package | 2000 V AC isolation enables direct heatsink mounting without thermal interface insulation, reducing assembly cost and thermal resistance. |
| Full-quadrant gate sensitivity | Identical ≤30 mA IGT and ≤1.5 V VGT across I/II/III quadrants simplifies driver design and eliminates quadrant-specific biasing circuitry. |
| High dv/dt immunity | 10 V/µs critical rate at 125 °C prevents false triggering from line transients, supporting reliable operation in noisy industrial AC mains environments. |
| Planar passivation structure | Enhances long-term stability of blocking characteristics and reduces parameter drift over temperature and lifetime vs. mesa-type triacs. |
| 150 °C junction rating | Enables operation in high-ambient-temperature enclosures (e.g., sealed motor drives) with reduced derating compared to 125 °C-rated devices. |

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 BTB20-600CW | Same 600 V VDRM, 20 A IT(RMS), TO-220FP package, but non-insulated (Viso = 0 V); requires insulating pad for heatsink mounting. | Lacks 2000 V isolation; unsuitable where chassis-grounded heatsinks are mandatory per safety standards. | Select only if isolation is handled externally and cost reduction is prioritized over assembly simplicity. |
| ON Semiconductor MAC220A | Lower 200 V VDRM, 20 A IT(RMS), TO-220 package, non-insulated; gate trigger current ≤50 mA (higher drive requirement). | Restricted to 120 VAC systems; insufficient for global 230/240 VAC industrial use. | Valid only for North American 120 VAC applications with relaxed isolation requirements. |
Compared with BCR20FM-12LB#BB0, the BTB20-600CW requires added thermal interface insulation to meet safety isolation, increasing thermal resistance and assembly steps, while the MAC220A lacks voltage rating and isolation for 230 VAC industrial deployment - making BCR20FM-12LB#BB0 the sole option meeting 600 V blocking, 2000 V isolation, and 20 A RMS in one TO-220FP device.

FAQ
What is the isolation voltage rating of the BCR20FM-12LB#BB0?
The BCR20FM-12LB#BB0 has a certified isolation voltage (Viso) of 2000 V AC for 1 minute between all main terminals (T1, T2, Gate) and the case. This rating is measured at Ta = 25 °C and confirms suitability for applications requiring reinforced insulation per IEC 60747-5-1, such as grounded-chassis industrial controls where user safety and system reliability depend on galvanic separation.
Does the BCR20FM-12LB#BB0 support triggering in all four quadrants?
The BCR20FM-12LB#BB0 supports triggering in Quadrants I, II, and III only - not Quadrant IV. Its datasheet explicitly specifies gate trigger parameters (IFGTI, IRGTI, IRGTIII) for these three quadrants with identical ≤30 mA current and ≤1.5 V voltage limits. Quadrant IV triggering is not characterized or guaranteed, and attempting it may result in inconsistent or failed turn-on.
What is the thermal resistance from junction to case for the BCR20FM-12LB#BB0?
The junction-to-case thermal resistance (Rth(j-c)) of the BCR20FM-12LB#BB0 is 2.3 °C/W, as specified for the #BB0 variant in the datasheet's Maximum Ratings table. This value applies under standard mounting conditions with greased interface and is essential for calculating maximum allowable case temperature to maintain Tj ≤ 150 °C under 20 A RMS load.
Is the BCR20FM-12LB#BB0 still in active production?
No - the BCR20FM-12LB#BB0 has an "EOL announced" status per the official Renesas ordering information table on page 8 of the datasheet. While Aetrix Electronics maintains limited legacy stock, new designs should consider alternative variants like #BG0 or #BH0 (both in mass production) or evaluate drop-in replacements with verified compatibility.
What is the maximum surge current rating for the BCR20FM-12LB#BB0?
The BCR20FM-12LB#BB0 has a non-repetitive surge on-state current (ITSM) rating of 200 A, defined as the peak value of a single 60 Hz sine-wave half-cycle (16.7 ms). This rating enables reliable handling of inrush currents from capacitive or highly inductive loads, provided the corresponding I²t value (167 A²s) is not exceeded and the device is adequately heatsinked to prevent cumulative thermal stress.
