Product details
Overview
BCR8CS-12LA#B00 from Renesas Electronics is a planar passivated, non-insulated triac rated for 8 A RMS on-state current and 600 V repetitive peak off-state voltage, designed for medium-power AC switching in solid-state relays and hybrid ICs. It features low gate trigger current (≤30 mA), 1.5 V typical on-state voltage at 12 A, and operates across –40°C to +125°C junction temperature.
For engineers reviewing the BCR8CS-12LA#B00 datasheet, BCR8CS-12LA#B00 pinout, BCR8CS-12LA#B00 application, or BCR8CS-12LA#B00 equivalent, this device serves as a high-sensitivity, TO-220S-packaged triac optimized for reliable phase-control and zero-crossing switching in industrial control and appliance motor drives where thermal stability and dv/dt immunity are critical.
Technical Context
The BCR8CS-12LA#B00 is a four-quadrant sensitive-gate triac with gate trigger currents specified for I, II, and III quadrants (≤30 mA), enabling robust turn-on under diverse AC phase conditions. Its critical rate of rise of off-state commutating voltage is 10 V/µs at Tj = 125°C, supporting stable operation with inductive loads.
Thermal performance is defined by a junction-to-case thermal resistance of 2.0°C/W, validated with case temperature measured on the T2 tab. The device uses planar passivation technology and is packaged in the non-insulated TO-220S (RENESAS code PRSS0004AB-A) outline, with terminals T1, T2 (dual), and Gate arranged in a 4-pin SC-83 configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RMS On-State Current | 8 A - Supports continuous AC load switching up to 8 A at Tc = 105°C with full-wave conduction. |
| Repetitive Peak Off-State Voltage | 600 V - Withstands 600 V AC line transients in 230 V mains applications without false triggering. |
| Gate Trigger Current (I/II/III) | ≤30 mA - Enables direct drive from microcontroller GPIO or low-power optocouplers without external amplification. |
| On-State Voltage | ≤1.5 V - Limits conduction loss to ≤12 W at 8 A, reducing heatsink requirements in compact designs. |
| Critical dv/dt (commutating) | 10 V/µs - Ensures reliable commutation with inductive loads like solenoids and AC motors without snubber networks. |
| Junction Temperature Range | –40°C to +125°C - Qualified for industrial ambient environments including enclosed control panels and HVAC systems. |
| Surge On-State Current | 80 A - Withstands 60 Hz half-cycle surges (e.g., motor startup inrush), improving system robustness. |
Pinout & Package
BCR8CS-12LA#B00 is housed in a non-insulated TO-220S package (JEITA SC-83, RENESAS code PRSS0004AB-A), featuring a metal tab (T2) for thermal and electrical connection. Pin assignment follows standard triac terminal labeling with dual T2 connections for mechanical stability and current sharing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (T1) | Anode 1 / Main Terminal 1 | Primary current path input; connects to AC line or load return in bidirectional switching configurations. |
| 2 (T2) | Anode 2 / Main Terminal 2 | Main current path output; electrically tied to metal tab for heatsinking and common reference in PCB layout. |
| 3 (Gate) | Control Input | Sensitive gate requiring ≤30 mA trigger; polarity-independent for quadrants I, II, and III operation. |
| 4 (T2) | Anode 2 / Main Terminal 2 (redundant) | Second T2 connection improves mechanical mounting rigidity and reduces contact resistance at high current. |
Key Features
| Feature | Design Value |
|---|---|
| High Sensitivity Gate | IGT ≤ 30 mA across all quadrants enables direct MCU/optocoupler drive without buffer stages. |
| Planar Passivation Structure | Enhances long-term reliability and moisture resistance in humid or contaminated industrial environments. |
| Non-Insulated TO-220S Package | Reduces thermal resistance (Rth(j-c) = 2.0°C/W) and simplifies heatsink integration via conductive metal tab. |
| 10 V/µs Commutating dv/dt Rating | Supports snubberless operation with inductive loads, lowering BOM count and board space in SSR modules. |
| 8 A RMS / 80 A Surge Rating | Provides margin for intermittent overloads such as compressor startup or transformer magnetizing inrush. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BTB08-600CW | Same 8 A/600 V rating but insulated TO-220 package (Rth(j-c) = 2.5°C/W); higher IGT (≤50 mA). | Preferred where electrical isolation between heatsink and circuit ground is mandatory (e.g., Class I appliances). | Select BTB08-600CW when creepage/clearance requirements exceed non-insulated design limits. |
| ON Semiconductor MAC8QY8G | 8 A/600 V, TO-220AB package, lower IGT (≤25 mA), but only rated for 8 A at Tc = 80°C (not 105°C). | Better suited for consumer-grade products with lower ambient thermal demands and tighter gate drive budgets. | Choose MAC8QY8G for cost-sensitive, lower-duty-cycle applications where full 105°C derating is not required. |
Compared with BTB08-600CW and MAC8QY8G, the BCR8CS-12LA#B00 delivers superior thermal capability at elevated case temperatures and maintains consistent gate sensitivity across all quadrants-critical for noise-immune operation in electrically noisy industrial settings.

FAQ
What is the maximum junction temperature specification for the BCR8CS-12LA#B00?
The BCR8CS-12LA#B00 has a specified junction temperature range of –40°C to +125°C. This allows operation in demanding industrial environments where ambient temperatures may exceed 85°C, provided thermal design maintains Tj ≤ 125°C under worst-case load and ambient conditions. Derating curves in the datasheet confirm 8 A RMS capability at Tc = 105°C.
Does the BCR8CS-12LA#B00 require a heatsink in standard applications?
Yes-the BCR8CS-12LA#B00 requires a heatsink for continuous 8 A RMS operation. With Rth(j-c) = 2.0°C/W and typical VTM ≈ 1.5 V, power dissipation reaches ~12 W at full load. Without heatsinking, junction temperature would exceed 125°C even at modest ambient temperatures. A properly sized aluminum heatsink with thermal grease is mandatory for rated performance.
Is the BCR8CS-12LA#B00 compatible with zero-crossing trigger circuits?
Yes-the BCR8CS-12LA#B00 supports zero-crossing operation due to its low and symmetric gate trigger current (≤30 mA) across quadrants I, II, and III. When paired with a zero-crossing optocoupler (e.g., MOC3041), it enables low-EMI, low-dv/dt switching ideal for lighting and heater control without audible noise or electromagnetic interference.
What is the meaning of "Non-Insulated Type" in the BCR8CS-12LA#B00 datasheet?
"Non-Insulated Type" means the metal tab (T2 terminal) is electrically connected to the internal semiconductor die and must be treated as a live circuit node. Unlike insulated TO-220 variants, no internal isolation barrier exists between the tab and T2-requiring careful PCB layout to ensure the heatsink remains at the same potential as T2 or is fully isolated from user-accessible surfaces per safety standards.
Can the BCR8CS-12LA#B00 replace older NEC triacs like the BCR8CM-12L?
Yes-the BCR8CS-12LA#B00 is a direct functional and pin-compatible successor to the NEC BCR8CM-12L, retaining identical TO-220S package, terminal arrangement, and electrical specifications (8 A/600 V, ≤30 mA IGT). Renesas confirms backward compatibility in merged documentation, making it suitable for legacy design refreshes without layout changes.
