Product details
Overview
BCR20KM-12LA-A8#X3 from Renesas Electronics is a planar passivated, insulated triac rated for 20 A RMS on-state current and 600 V repetitive peak off-state voltage, designed for phase-control AC power switching in mains-connected consumer appliances. It features 2000 V isolation voltage, 30 mA gate trigger current (IGT), and TO-220FN package with integrated heatsink mounting flange - used in vacuum cleaners, light dimmers, and electric heaters.
For engineers reviewing the BCR20KM-12LA-A8#X3 datasheet, BCR20KM-12LA-A8#X3 pinout, BCR20KM-12LA-A8#X3 application, or BCR20KM-12LA-A8#X3 equivalent, key selection criteria include IT(RMS) derating at Tc = 85°C, dv/dt immunity of 10 V/µs at Tj = 125°C, gate sensitivity across quadrants I and III, thermal resistance Rth(j-c) ≤ 2.0 °C/W, and UL recognition under Yellow Card E223904.
Technical Context
This triac operates in all four quadrants with verified gate trigger characteristics in Quadrants I and III, supporting both positive and negative gate drive relative to T2. Its planar passivation structure ensures stable blocking performance up to 720 V non-repetitive peak off-state voltage (VDSM) under transient conditions.
The device integrates galvanic isolation between main terminals (T1/T2/Gate) and case, validated at 2000 V AC for 1 minute. Thermal design relies on junction-to-case conduction through the TO-220FN metal tab, with maximum junction temperature limited to +125°C and storage range from –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 20 A - Sustains full-wave sinusoidal load current at Tc = 85°C without thermal runaway |
| VDRM | 600 V - Blocks standard 230 VAC mains with ≥2× safety margin against line surges |
| IGT (Quadrant I/III) | 30 mA - Enables low-power microcontroller GPIO direct drive without external amplification |
| Viso | 2000 V AC - Meets reinforced insulation requirements for Class I appliance safety standards |
| Rth(j-c) | 2.0 °C/W - Allows thermal design using standard heatsink calculations with greased interface |
| (dv/dt)c | 10 V/µs at Tj = 125°C - Resists false triggering during fast-rising noise transients on AC lines |
| ITSM | 200 A - Withstands single-cycle 60 Hz surge (e.g., motor startup inrush) without failure |
Pinout & Package
BCR20KM-12LA-A8#X3 uses the TO-220FN package: insulated plastic body with metal tab (case) for heatsinking, 3-pin vertical leadform, 2.0 g mass, and EIAJ-standard dimensions including 10 mm height (A), 15 mm width (D), and 3.6 mm lead pitch (e).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (T1) | Main Terminal 1 | Anode-side main current path; connected to load return or neutral in typical snubberless dimmer layouts |
| 2 (T2) | Main Terminal 2 | Cathode-side main current path; referenced for gate drive polarity in Quadrant I/III triggering |
| 3 (Gate) | Control Input | Triggers conduction when pulsed with ≥30 mA; polarity-sensitive relative to T2 for quadrant-specific turn-on |
Key Features
| Feature | Design Value |
|---|---|
| UL Recognition | Yellow Card E223904 - Confirms compliance with UL 1557 for reinforced insulation in end equipment |
| Insulated Type | 2000 V isolation barrier - Eliminates need for separate insulating hardware in PCB-mount applications |
| Planar Passivation | Stable VDRM over lifetime - Prevents surface leakage degradation under humid or contaminated environments |
| High Sensitivity Gate | IGT ≤ 30 mA - Reduces gate driver component count and power loss in battery-powered or low-voltage control systems |
| TO-220FN Package | Metal tab with isolated leads - Enables direct heatsink mounting while maintaining creepage/clearance for safety certification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac-based AC power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BTB20-600B | Same IT(RMS) = 20 A, VDRM = 600 V, but non-insulated TO-220AB package (Viso = 0 V) | Requires external isolation barrier and creepage extension for Class I safety compliance | Select when cost optimization outweighs safety certification effort and board space allows isolation components |
| ON Semiconductor MAC220A8 | Lower IT(RMS) = 8 A, same VDRM = 600 V, TO-220 package with insulated option (MAC220A8FP) | Limited to sub-1 kW loads; gate trigger current higher at 50 mA | Choose for lower-power auxiliary circuits where BCR20KM-12LA-A8#X3's 20 A capacity is excessive |
Compared with BTB20-600B and MAC220A8, BCR20KM-12LA-A8#X3 uniquely combines 20 A current handling, 2000 V isolation, and UL recognition in a single TO-220FN package - reducing BOM count and simplifying safety certification for Class I consumer appliances.

FAQ
What is the maximum allowable case temperature for continuous operation of BCR20KM-12LA-A8#X3?
The BCR20KM-12LA-A8#X3 supports continuous RMS on-state current of 20 A only when case temperature (Tc) is maintained at ≤85°C, as specified in the Maximum Ratings table. Exceeding this limit reduces safe operating current per the derating curve on page 4 of the datasheet. Thermal design must ensure adequate heatsinking and airflow to sustain Tc ≤85°C under worst-case ambient and load conditions for BCR20KM-12LA-A8#X3 reliability.
Does BCR20KM-12LA-A8#X3 support gate triggering in all four quadrants?
BCR20KM-12LA-A8#X3 is characterized and guaranteed for reliable gate triggering in Quadrants I and III only, with IGT ≤30 mA tested under VD = 6 V, RL = 6 Ω, and RG = 330 Ω. Quadrants II and IV triggering is not specified in the datasheet and should not be assumed functional for production designs using BCR20KM-12LA-A8#X3.
What is the isolation voltage rating and test condition for BCR20KM-12LA-A8#X3?
The BCR20KM-12LA-A8#X3 provides 2000 V AC isolation voltage (Viso) between all main terminals (T1, T2, Gate) and the metal case, verified at Ta = 25°C for 1 minute. This rating satisfies reinforced insulation requirements per IEC 60747-6 and enables direct mounting to grounded heatsinks without additional insulation barriers in BCR20KM-12LA-A8#X3-based designs.
Is BCR20KM-12LA-A8#X3 RoHS compliant and halogen-free?
Yes, BCR20KM-12LA-A8#X3 complies with EU RoHS Directive 2011/65/EU, as confirmed by Renesas' environmental compliance documentation. The device uses lead-free terminations and halogen-free molding compound, meeting JEDEC JS709B and IPC-1752A material declaration standards applicable to BCR20KM-12LA-A8#X3.
What is the critical rate of rise of off-state commutating voltage (dv/dt)c for BCR20KM-12LA-A8#X3?
The BCR20KM-12LA-A8#X3 has a minimum critical commutating dv/dt rating of 10 V/µs at Tj = 125°C, measured under inductive load conditions with di/dt = –10 A/ms and VD = 400 V. This parameter defines the maximum voltage transient slope the device can withstand during turn-off without unintended re-triggering - a key specification for snubberless operation in BCR20KM-12LA-A8#X3 applications.
