Product details
Overview
BCR8FM-20LA#BH0 from Renesas Electronics is a 1000 V, 8 A insulated triac in TO-220FPA package, designed for medium-power AC phase control. It delivers 80 A non-repetitive surge current, supports 2000 V isolation, and operates across –40 °C to +125 °C junction temperature-enabling robust motor and heater control in industrial solid-state relays.
For engineers reviewing the BCR8FM-20LA#BH0 datasheet, BCR8FM-20LA#BH0 pinout, BCR8FM-20LA#BH0 application, or BCR8FM-20LA#BH0 equivalent, key selection criteria include repetitive peak off-state voltage (1000 V), RMS on-state current (8 A), gate trigger current (30 mA), isolation voltage (2000 V), and thermal resistance (3.7 °C/W).
Technical Context
This triac uses planar passivation technology and features insulated construction with T1/T2/Gate terminals isolated from the case. Its critical dv/dt rating of 10 V/μs at 125 °C ensures reliable commutation under inductive loads, while latching and holding currents remain stable across –40 °C to +125 °C.
Gate triggering is specified across three quadrants (I, II, III) with identical 1.5 V max trigger voltage and 30 mA max trigger current at 25 °C. The device meets commercial-frequency sine-wave conduction requirements with 360° full-wave capability and 26 A²s I²t rating for single-cycle surge protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 1000 V - Maximum repetitive peak off-state voltage; defines maximum AC line voltage it can block reliably. |
| IT(RMS) | 8 A - Continuous RMS on-state current at Tc = 88 °C; sets thermal design baseline for heatsink sizing. |
| Viso | 2000 V AC - Isolation voltage between terminals and case for 1 minute; enables safe operation in grounded-heatsink configurations. |
| ITSM | 80 A - Non-repetitive surge current (60 Hz, 1 cycle); determines short-circuit withstand capability. |
| Rth(j–c) | 3.7 °C/W - Junction-to-case thermal resistance; used with case temperature to calculate max junction temp under load. |
| (dv/dt)c | 10 V/μs - Minimum critical rate of rise of off-state voltage at 125 °C; prevents false turn-on during fast transients. |
| VTM | 1.6 V max - On-state voltage at 12 A instantaneous; directly impacts conduction loss and power dissipation. |
Pinout & Package
BCR8FM-20LA#BH0 is housed in the TO-220FPA package (RENESAS code PRSS0003AP-A), an insulated variant of TO-220 with plastic body and metal tab electrically isolated from internal terminals. The case serves as a mechanical mounting surface only-not a circuit node.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| T1 | Main Terminal 1 | Anode-side main current path; connects to AC line or load return depending on circuit topology. |
| T2 | Main Terminal 2 | Cathode-side main current path; typically connected to AC neutral or load input in standard configurations. |
| G | Gate | Control input for triggering conduction in all four quadrants; requires ≤30 mA pulse for reliable turn-on. |
Key Features
| Feature | Design Value |
|---|---|
| Insulated TO-220FPA package | Enables direct mounting to grounded heatsinks without external insulation, reducing system BOM and assembly cost. |
| Planar passivation structure | Provides stable electrical characteristics over time and temperature, improving long-term reliability in industrial environments. |
| Three-quadrant gate trigger capability | Supports simplified gate drive circuits by eliminating need for polarity reversal in AC phase control applications. |
| 26 A²s I²t rating | Defines fusing energy limit; allows coordination with upstream fuses for selective protection in AC power stages. |
| 125 °C max junction temperature | Permits operation in high-ambient industrial enclosures without derating below 8 A RMS at Tc = 88 °C. |

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 BTB08-600CW | 600 V VDRM, same 8 A IT(RMS), non-insulated TO-220 package, 1000 V isolation rating. | Requires external insulation for grounded heatsink use; lower voltage rating limits 400 VAC three-phase compatibility. | Select when cost sensitivity outweighs isolation requirement and line voltage stays ≤277 VAC. |
| ON Semiconductor MAC8QD8G | 800 V VDRM, 8 A IT(RMS), insulated TO-220 package, 2500 V isolation, higher 15 V/μs (dv/dt)c. | Better noise immunity and higher isolation margin; slightly larger package footprint (TO-220AB vs TO-220FPA). | Prefer for harsh EMI environments or safety-critical designs requiring >2000 V isolation margin. |
Compared with BCR8FM-20LA#BH0, BTB08-600CW trades isolation and voltage headroom for lower cost, while MAC8QD8G offers enhanced dv/dt immunity and isolation at the expense of minor layout adaptation-neither is pin-compatible, but both serve overlapping AC control functions with verified thermal and surge performance.

FAQ
What is the maximum allowable case temperature for continuous operation of BCR8FM-20LA#BH0?
The BCR8FM-20LA#BH0 supports continuous operation at up to 88 °C case temperature when delivering its rated 8 A RMS on-state current. This value is defined in the Maximum Ratings table and corresponds to the thermal condition where junction temperature remains within its –40 °C to +125 °C operating range. Exceeding 88 °C requires current derating per the Allowable Case Temperature vs. RMS On-State Current curve on page 4 of the datasheet. BCR8FM-20LA#BH0 must be mounted on a heatsink with adequate thermal interface to maintain this limit.
Does BCR8FM-20LA#BH0 support gate triggering in all four quadrants?
BCR8FM-20LA#BH0 supports gate triggering in Quadrants I, II, and III as explicitly defined in the Electrical Characteristics table-each with identical 30 mA max gate trigger current and 1.5 V max gate trigger voltage at 25 °C. Quadrant IV triggering is not characterized or guaranteed in the datasheet. For full four-quadrant operation, designers should verify gate drive polarity and timing alignment with the test circuits shown on page 6. BCR8FM-20LA#BH0 is optimized for standard phase-control topologies using I/III or II/III combinations.
What is the significance of the "20" in the part number BCR8FM-20LA#BH0?
The "20" in BCR8FM-20LA#BH0 denotes the voltage class code, indicating a 1000 V repetitive peak off-state voltage (VDRM) rating. Renesas uses standardized voltage class codes where "20" maps to 1000 V, "12" to 600 V, and "16" to 800 V. This coding is confirmed in the Maximum Ratings table on page 1 and aligns with industry conventions for triac voltage classification. BCR8FM-20LA#BH0 is therefore rated for use on 400 VAC three-phase and 277 VAC single-phase distribution systems with safety margin.
Can BCR8FM-20LA#BH0 be used without a heatsink in low-duty-cycle applications?
BCR8FM-20LA#BH0 may operate without a heatsink only at significantly reduced current levels and duty cycles, as shown in the Allowable Ambient Temperature vs. RMS On-State Current curves on page 4. At 25 °C ambient and natural convection (no fins), the device sustains only ~2.5 A RMS continuously. For any application approaching its 8 A rating-or operating above 40 °C ambient-a heatsink is mandatory. The 3.7 °C/W junction-to-case thermal resistance means even modest power dissipation rapidly elevates junction temperature. BCR8FM-20LA#BH0 must be evaluated thermally using actual load profiles before omitting heatsinking.
Is BCR8FM-20LA#BH0 compliant with RoHS and lead-free assembly requirements?
Yes, BCR8FM-20LA#BH0 is RoHS-compliant and qualified for lead-free reflow soldering per JEDEC J-STD-020. The datasheet confirms compliance in the "Environmental Information" section referenced via Renesas' general handling notes, and the ordering code suffix "#BH0" indicates standard lead-free finish. The device meets Pb-free soldering peak temperatures up to 260 °C for 10 seconds. BCR8FM-20LA#BH0 is suitable for modern SMT and through-hole assembly processes without exemption requests or special handling.
