Product details
Overview
BCR25FM-12LB#BH0 from Renesas Electronics is a 600V, 25A insulated triac in TO-220FPA package, designed for medium-power AC switching in heater control, copiers, and contactless AC load management. It features 2000 V isolation voltage, 150 °C junction temperature rating, and gate trigger current of 50 mA across all quadrants.
For engineers reviewing the BCR25FM-12LB#BH0 datasheet, BCR25FM-12LB#BH0 pinout, BCR25FM-12LB#BH0 application, or BCR25FM-12LB#BH0 equivalent, key selection criteria include RMS on-state current (25 A), repetitive peak off-state voltage (600 V), thermal resistance (2.8 °C/W), and insulated package suitability for safety-critical AC mains interfaces.
Technical Context
This triac operates in all four quadrants with symmetrical gate trigger characteristics: IFGTI, IRGTI, and IRGTIII each rated at 50 mA at 25 °C. Its planar passivation structure ensures stable dv/dt immunity-10 V/μs at 125 °C and 1 V/μs at 150 °C-critical for inductive load commutation.
The device uses an insulated TO-220FPA package with creepage/clearance optimized for 2000 V AC isolation (1 min), enabling direct mounting to grounded heatsinks without additional insulation barriers. Thermal design is constrained by Rth(j-c) = 2.8 °C/W and maximum case temperature of 62 °C at full 25 A RMS conduction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 600 V - Maximum repetitive off-state voltage; defines safe blocking capability across AC mains cycles. |
| IT(RMS) | 25 A - Continuous RMS current handling at Tc = 62 °C; determines usable load power in resistive/inductive applications. |
| Viso | 2000 V AC - Isolation voltage between terminals and case; enables direct heatsink mounting without insulating pads. |
| Tj max | +150 °C - Maximum junction temperature; sets thermal derating limits and heatsink sizing requirements. |
| Rth(j-c) | 2.8 °C/W - Junction-to-case thermal resistance; used to calculate temperature rise under given power dissipation. |
| (dv/dt)c | 10 V/μs @ 125 °C - Critical rate of rise of off-state voltage before unintended turn-on; impacts snubber design for inductive loads. |
| IGM | 2 A - Peak gate current capability; supports robust triggering even with aging or high-impedance gate drive circuits. |
Pinout & Package
BCR25FM-12LB#BH0 uses the TO-220FPA package (Renesas code PRSS0003AP-A), featuring insulated mounting tab and 3-terminal configuration optimized for high-voltage AC switching with creepage compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| T1 | Main terminal 1 | Anode-side main current path; connected to AC line or load return depending on circuit topology. |
| T2 | Main terminal 2 | Cathode-side main current path; forms bidirectional conduction path with T1 during triggered half-cycles. |
| G | Gate | Control input for all-quadrant triggering; requires ≤2.0 V and ≥50 mA pulse to initiate conduction in any quadrant. |
Key Features
| Feature | Design Value |
|---|---|
| All-quadrant gate sensitivity | IFGTI/IRGTI/IRGTIII ≤ 50 mA at 25 °C - Enables reliable triggering from microcontroller GPIOs without external amplification. |
| Insulated package | Viso = 2000 V AC - Eliminates need for isolating thermal pads when mounting to grounded metal chassis or heatsinks. |
| High dv/dt immunity | (dv/dt)c = 10 V/μs @ 125 °C - Reduces false triggering risk in noisy industrial environments with fast-switching adjacent loads. |
| Planar passivation | Stable leakage and breakdown performance over lifetime - Ensures long-term reliability in continuous-duty heater and motor control. |
| Thermal robustness | Tj = –40 to +150 °C operating range - Supports deployment in unventilated enclosures or high-ambient industrial settings. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac-based AC switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BTB24-600BW | 24 A RMS, 600 V VDRM, TO-220AB package (non-insulated), Rth(j-c) = 2.5 °C/W | Requires insulated mounting hardware for 2000 V isolation; lower IT(RMS) limits max load power | Select when cost-sensitive designs can accommodate external insulation and accept 4% lower current rating. |
| ON Semiconductor MAC225A8G | 25 A RMS, 600 V VDRM, TO-220 package (non-insulated), Rth(j-c) = 2.7 °C/W, Viso not specified | No certified isolation voltage; unsuitable for direct heatsink mounting in safety-critical mains interfaces | Choose only for double-insulated or low-risk AC applications where isolation certification is not required. |
Compared with BCR25FM-12LB#BH0, BTB24-600BW offers slightly better thermal resistance but lacks integrated isolation, while MAC225A8G matches current rating but provides no isolation specification-making BCR25FM-12LB#BH0 the sole option among the three with certified 2000 V AC isolation and full 25 A capability in one package.

FAQ
What is the maximum RMS on-state current rating for BCR25FM-12LB#BH0?
The BCR25FM-12LB#BH0 has a rated RMS on-state current (IT(RMS)) of 25 A under standard test conditions: commercial frequency sine full-wave, 360° conduction, and case temperature (Tc) maintained at 62 °C. This rating assumes proper heatsinking and thermal management per the datasheet's allowable case temperature curves.
Does BCR25FM-12LB#BH0 support all-quadrant triggering, and what are the gate trigger current requirements?
Yes, BCR25FM-12LB#BH0 supports all-quadrant triggering with confirmed gate trigger current ratings of 50 mA for IFGTI, IRGTI, and IRGTIII at 25 °C. Each quadrant exhibits identical gate sensitivity, enabling flexible control architecture without polarity constraints on gate drive signals.
What is the isolation voltage specification for BCR25FM-12LB#BH0, and how is it tested?
The BCR25FM-12LB#BH0 provides a certified isolation voltage (Viso) of 2000 V AC, measured for 1 minute at Ta = 25 °C between all main terminals (T1, T2, G) and the case. This rating permits direct mounting to grounded heatsinks without additional insulating hardware, simplifying mechanical design and improving thermal performance.
What package type does BCR25FM-12LB#BH0 use, and how does it differ from TO-220FP?
BCR25FM-12LB#BH0 uses the TO-220FPA package (Renesas code PRSS0003AP-A), which features an insulated mounting tab and modified leadform versus the non-insulated TO-220FP (PRSS0003AG-A). The "A" suffix denotes the insulated variant, critical for achieving the 2000 V isolation rating without external barriers.
Can BCR25FM-12LB#BH0 be used in zero-cross switching applications, and what gate drive considerations apply?
Yes, BCR25FM-12LB#BH0 is suitable for zero-cross switching due to its symmetrical all-quadrant gate characteristics and low gate trigger voltage (≤2.0 V). For reliable zero-cross operation, gate drive must deliver ≥50 mA pulses within ±100 μs of the zero-crossing point, with adequate di/dt and dv/dt immunity ensured by the device's 10 V/μs (dv/dt)c rating at 125 °C.
