Product details
Overview
BCR20KM-12LB-A8#X2 from Renesas Electronics is a 600 V, 20 A insulated triac in TO-220FN package, rated for 150°C maximum junction temperature and designed for AC mains switching in medium-power resistive and inductive loads. It features 2000 V isolation voltage, 30 mA gate trigger current (IGT), and critical dv/dt immunity of 10 V/µs at 125°C.
For engineers reviewing the BCR20KM-12LB-A8#X2 datasheet, BCR20KM-12LB-A8#X2 pinout, BCR20KM-12LB-A8#X2 application, or BCR20KM-12LB-A8#X2 equivalent, key selection criteria include RMS on-state current derating at elevated case temperatures, gate sensitivity under high junction temperature, and thermal resistance (Rth(j-c) = 2.0°C/W) for heatsink design in vacuum cleaners, light dimmers, and heater controls.
Technical Context
This triac operates in all four quadrants with verified I/III quadrant triggering characteristics, supporting phase-control and zero-crossing switching topologies. Its planar passivation structure ensures stable blocking behavior up to 600 V repetitive peak off-state voltage (VDRM) and 720 V non-repetitive peak (VDSM).
Thermal performance is defined by junction-to-case thermal resistance of 2.0°C/W, requiring heatsinking for continuous 20 A RMS conduction at Tc ≤ 110°C. Gate drive compliance is specified at VD = 6 V, RL = 6 Ω, RG = 330 Ω, with guaranteed IGT ≤ 30 mA across –40°C to +150°C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 600 V - Sustains full AC mains voltage (230 VAC RMS → ~325 V peak) with margin for transients |
| IT(RMS) | 20 A - Supports continuous load current up to 4.6 kW at 230 VAC with proper heatsinking |
| Tj(max) | +150°C - Enables operation in high-temperature environments where standard 125°C triacs fail |
| Viso | 2000 V AC - Provides reinforced insulation between main terminals/gate and metal tab for safety-critical appliances |
| Rth(j-c) | 2.0°C/W - Dictates minimum heatsink thermal resistance required to maintain Tj ≤ 150°C at 20 A conduction |
| (dv/dt)c | 10 V/µs @ Tj=125°C - Determines immunity to false triggering from fast-rising line noise or commutation spikes |
| IGT | 30 mA max - Specifies minimum gate drive capability needed from microcontroller GPIO or optocoupler output |
Pinout & Package
BCR20KM-12LB-A8#X2 uses the TO-220FN (flat no-tab) package with insulated mounting surface and 2.0 g mass. The metal backside is electrically isolated from all terminals, enabling direct heatsink mounting without insulating washers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| T1 | Main Terminal 1 | Anode-side connection; carries full load current in both directions during conduction |
| T2 | Main Terminal 2 | Cathode-side connection; referenced to gate for triggering in Quadrants I and III |
| Gate | Control Input | Low-power input that initiates conduction when IGT ≥ 30 mA is applied with proper polarity relative to T2 |
Key Features
| Feature | Design Value |
|---|---|
| Insulated TO-220FN package | Enables direct metal heatsink mounting without electrical isolation hardware, reducing assembly cost and thermal interface resistance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BTB20-600B | Same 20 A/600 V rating but 125°C Tj(max); Rth(j-c) = 2.5°C/W; non-insulated TO-220AB package | Requires insulating pad for heatsink mounting; lower thermal margin in compact enclosures | Select when cost sensitivity outweighs thermal headroom and isolation requirements |
| ON Semiconductor Q6008LH4 | 20 A/600 V, 150°C Tj(max), insulated TO-220 package; IGT = 50 mA; Viso = 2500 V | Higher gate drive requirement; superior isolation for medical-grade equipment | Select when enhanced safety certification (e.g., UL 60730-1 Annex H) is mandatory |
Compared with BCR20KM-12LB-A8#X2, BTB20-600B trades thermal robustness for lower cost and wider distributor availability, while Q6008LH4 prioritizes higher isolation and safety margins at the expense of gate sensitivity-making BCR20KM-12LB-A8#X2 optimal for thermally constrained consumer appliance designs requiring 150°C operation without over-spec'ing gate drive.

FAQ
What is the maximum allowable case temperature for continuous 20 A RMS operation of BCR20KM-12LB-A8#X2?
The BCR20KM-12LB-A8#X2 datasheet specifies that 20 A RMS conduction is rated at Tc = 110°C. Exceeding this temperature requires derating per the "Allowable Case Temperature vs. RMS On-State Current" curve on page 4. At Tc = 125°C, the maximum sustainable IT(RMS) drops to approximately 16 A. Thermal design must ensure Rth(j-c) + Rth(c-sink) + Rth(sink-amb) keeps Tj ≤ 150°C under worst-case ambient and load conditions. BCR20KM-12LB-A8#X2's 2.0°C/W Rth(j-c) value is critical for calculating required heatsink performance.
Does BCR20KM-12LB-A8#X2 support gate triggering in all four quadrants?
BCR20KM-12LB-A8#X2 is characterized and guaranteed for triggering in Quadrants I (T2+, G+) and III (T2–, G–), as confirmed by test procedures I and III in the datasheet. While it may conduct in Quadrants II and IV under certain conditions, Renesas does not specify or guarantee performance there. Designers must use gate drive circuits aligned with I/III quadrant polarity-such as optocouplers with cathode tied to T2-to ensure reliable turn-on. BCR20KM-12LB-A8#X2's gate trigger voltage remains ≤1.5 V across these quadrants at Tj = 25°C.
How does the 2000 V isolation voltage of BCR20KM-12LB-A8#X2 impact system-level safety certification?
The 2000 V AC isolation rating (Viso) of BCR20KM-12LB-A8#X2 meets reinforced insulation requirements per IEC 60730-1 Annex H and UL 1459 for Class I appliances, allowing direct mounting to grounded heatsinks without additional creepage/clearance barriers. This eliminates the need for insulating pads or sleeves in vacuum cleaner or heater designs, simplifying mechanical assembly and improving thermal transfer. BCR20KM-12LB-A8#X2's TO-220FN package maintains this isolation across its full temperature range (–40°C to +150°C), supporting certification validity over product lifetime.
Can BCR20KM-12LB-A8#X2 replace older 125°C triacs in existing designs without layout changes?
BCR20KM-12LB-A8#X2 shares identical TO-220FN mechanical dimensions and pinout with legacy 125°C triacs like BCR20KM-12L, enabling drop-in replacement in most cases. However, its higher 150°C junction rating allows increased power density or extended lifetime in thermally constrained layouts. Designers must verify gate drive compatibility (IGT ≤ 30 mA remains unchanged) and confirm that existing heatsinking supports the same thermal resistance-since Rth(j-c) is identical at 2.0°C/W, no PCB or mechanical redesign is needed solely for thermal reasons. BCR20KM-12LB-A8#X2 thus provides immediate reliability uplift without requalification overhead.
What is the surge current rating of BCR20KM-12LB-A8#X2 and how is it validated?
BCR20KM-12LB-A8#X2 has a non-repetitive surge on-state current (ITSM) rating of 200 A for one full 60 Hz sine cycle (16.7 ms), corresponding to an I²t rating of 167 A²s. This is validated per JEDEC standards using half-wave 60 Hz surge testing, ensuring robustness against motor startup inrush, transformer magnetizing currents, and capacitor charging spikes. The device's planar passivation structure prevents localized hot-spot formation during such events. For BCR20KM-12LB-A8#X2, this surge capability directly enables use in copy machine paper feed solenoids and vacuum cleaner brush motors without external current-limiting circuitry.
