Product details
Overview
BCR20KM-12LB-AN#X6 from Renesas Electronics is a 20 A, 600 V insulated triac in TO-220FN package, rated for 150°C maximum junction temperature, with 2000 V isolation voltage and 30 mA gate trigger current - used for AC power control in vacuum cleaners, electric heaters, and light dimmers.
For engineers reviewing the BCR20KM-12LB-AN#X6 datasheet, BCR20KM-12LB-AN#X6 pinout, BCR20KM-12LB-AN#X6 application, or BCR20KM-12LB-AN#X6 equivalent, this page delivers verified triac specifications, thermal derating curves, gate trigger behavior across temperature, dv/dt immunity, and real-world control circuit guidance per Renesas' Rev.2.00 datasheet.
Technical Context
This triac operates in all four quadrants (I, II, III, IV) with symmetrical gate trigger characteristics, supporting phase-angle and zero-crossing control topologies. Its planar passivation structure ensures stable blocking performance up to 150°C junction temperature and 720 V non-repetitive peak off-state voltage.
It features high commutation robustness: critical dv/dt rating of 10 V/µs at 125°C and 1 V/µs at 150°C under inductive load conditions (di/dt = –10 A/ms), with thermal resistance Rth(j–c) = 2.0°C/W enabling reliable conduction at 20 A RMS with proper heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 600 V - guarantees repetitive blocking capability in AC mains applications up to 240 V RMS with safety margin |
| IT(RMS) | 20 A - continuous RMS on-state current at Tc = 110°C, defining heatsink sizing baseline |
| Tj(max) | +150°C - extended junction temperature rating enables higher ambient operation vs. standard 125°C triacs |
| Viso | 2000 V AC - reinforced insulation between terminals and case supports Class I safety compliance in consumer appliances |
| IGT | 30 mA max - low gate trigger current reduces driver stage power loss and simplifies optocoupler selection |
| Rth(j–c) | 2.0°C/W - quantifies thermal path efficiency from junction to case, critical for calculating safe operating area |
| (dv/dt)c | 10 V/µs @ Tj=125°C - defines minimum snubber requirements for inductive loads like motor windings |
Pinout & Package
BCR20KM-12LB-AN#X6 uses the TO-220FN package: insulated plastic housing with metal tab (electrically isolated from terminals), 3-pin vertical through-hole outline, 2.0 g mass, and standardized EIAJ/JEDEC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| T1 | Main Terminal 1 | Anode-side main current path; connects to load return or neutral in single-phase AC circuits |
| T2 | Main Terminal 2 | Cathode-side main current path; connects to AC line input or hot side in phase-control configurations |
| Gate | Control Electrode | Triggers conduction when forward-biased relative to T1; polarity determines quadrant sensitivity (I/III preferred) |
Key Features
| Feature | Design Value |
|---|---|
| Insulated Package | 2000 V isolation enables direct mounting to grounded heatsinks without insulating washers |
| 150°C Junction Rating | Supports sustained 20 A RMS operation in compact enclosures where ambient exceeds 85°C |
| Planar Passivation | Improves long-term reliability under humidity and thermal cycling vs. mesa-structured triacs |
| Quadrant I/III Optimization | Guaranteed low IGT in I/III quadrants reduces gate drive complexity in standard optocoupler-based drivers |
| High Surge Withstand | 200 A non-repetitive surge (60 Hz, 1 cycle) accommodates motor startup inlets and transformer inrush |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac-based AC power control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BTB20-600B | Same 20 A/600 V rating, but 125°C Tj(max); TO-220AB (non-insulated) package requires isolation hardware | Lacks 2000 V isolation; unsuitable for direct heatsink mounting without mica washer | Select only if cost-sensitive and PCB layout allows added insulation components |
| ON Semiconductor MAC20M-600 | 20 A/600 V, 150°C Tj(max), but 1000 V Viso; TO-220AB package | Half the isolation voltage; requires external creepage/clearance reinforcement for Class I safety | Acceptable only in non-safety-critical industrial controls with full system-level isolation design |
Compared with BCR20KM-12LB-AN#X6, BTB20-600B trades isolation for lower cost and MAC20M-600 sacrifices isolation margin for broader distributor availability - neither matches the integrated safety, thermal headroom, and simplified thermal design of the Renesas insulated 150°C triac.

FAQ
What is the maximum junction temperature rating for BCR20KM-12LB-AN#X6?
The BCR20KM-12LB-AN#X6 has a guaranteed maximum junction temperature of +150°C, confirmed in Renesas' Rev.2.00 datasheet. This exceeds standard triac ratings (typically +125°C), allowing operation in thermally constrained environments such as sealed appliance enclosures. Derating curves in the datasheet define allowable RMS current versus case temperature, ensuring safe conduction at 20 A up to Tc = 110°C.
Does BCR20KM-12LB-AN#X6 require an insulating washer when mounted to a heatsink?
No, BCR20KM-12LB-AN#X6 does not require an insulating washer because it uses the TO-220FN insulated package with 2000 V AC isolation between terminals and case. The metal tab is electrically isolated, enabling direct mounting to grounded heatsinks - a key design advantage over non-insulated TO-220AB variants like BTB20-600B.
What is the gate trigger current specification for BCR20KM-12LB-AN#X6?
The gate trigger current (IGT) for BCR20KM-12LB-AN#X6 is specified as ≤30 mA maximum at Tj = 25°C, VD = 6 V, RL = 6 Ω, and RG = 330 Ω (Test Procedure I). This low IGT value simplifies driver design and supports compatibility with common optocouplers such as MOC3021 or IL420 without additional amplification stages.
Can BCR20KM-12LB-AN#X6 be used in zero-crossing switching applications?
Yes, BCR20KM-12LB-AN#X6 supports zero-crossing switching due to its symmetrical gate trigger characteristics across quadrants I and III. When paired with a zero-crossing optocoupler (e.g., MOC3041), it enables low-EMI, low-dv/dt turn-on ideal for resistive loads like heaters and incandescent lamps - though phase-angle control remains viable for motor and dimmer use cases.
What is the critical rate of rise of off-state commutating voltage (dv/dt)c for BCR20KM-12LB-AN#X6?
The critical (dv/dt)c for BCR20KM-12LB-AN#X6 is 10 V/µs at Tj = 125°C and 1 V/µs at Tj = 150°C under inductive load conditions (di/dt = –10 A/ms). These values define the minimum snubber network (RC) required to prevent false triggering during commutation - especially critical in motor control and transformer-coupled applications.
