Product details
Overview
BCR08AM-14A#BD0 from Renesas Electronics is a 700 V, 0.8 A planar passivated triac in TO-92 package, designed for AC phase control in low-power consumer appliances. It delivers 8 A non-repetitive surge current, operates up to 125 °C junction temperature, and features 5 mA gate trigger current (Quadrants I/II/III) for robust turn-on under noisy conditions - used in washing machine motor speed control.
For engineers reviewing the BCR08AM-14A#BD0 datasheet, BCR08AM-14A#BD0 pinout, BCR08AM-14A#BD0 application, or BCR08AM-14A#BD0 equivalent, this page provides verified electrical specs, thermal derating curves, gate trigger behavior across temperature, dv/dt immunity, and real-world AC load switching context for residential appliance design.
Technical Context
The BCR08AM-14A#BD0 is a three-quadrant sensitive-gate triac optimized for zero-crossing and random-phase AC switching in resistive and inductive loads. Its 50 °C/W junction-to-case thermal resistance and 0.5 V/μs critical commutating dv/dt rating at 125 °C define its safe operating area in fan motor drivers and solid-state relay modules.
Gate trigger characteristics are specified across all three active quadrants (I, II, III) with identical 2.0 V max VGT and 5 mA max IGT, enabling reliable firing with simple RC or optocoupler-based drive circuits without polarity constraints on gate voltage relative to T2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 700 V - blocks full AC mains waveform (e.g., 240 V RMS + margin) without conduction in off-state |
| IT(RMS) | 0.8 A - continuous RMS current handling at 67 °C case temperature, suitable for <100 W AC loads |
| ITSM | 8 A - withstands single-cycle 60 Hz surge (e.g., motor startup inrush), limiting need for external fusing |
| IGT (I/II/III) | 5 mA max - enables direct drive from microcontroller GPIO or low-current optocouplers like MOC3021 |
| (dv/dt)c | 0.5 V/μs - minimum rate of voltage rise before unintended turn-on; requires snubber only for highly inductive loads |
| Rth(j-c) | 50 °C/W - defines thermal path from junction to T2 terminal; mandates heatsinking above ~0.4 A RMS in sealed enclosures |
| Tj Range | –40 to +125 °C - supports operation in ambient temperatures up to 85 °C with proper derating per curve on page 4 |
Pinout & Package
BCR08AM-14A#BD0 uses the PRSS0003DJ-A package, a standard TO-92 variant with 0.23 g mass and JEITA SC-43A footprint. Pin assignment follows the 1–2–3 layout: Terminal 1 = T1 (Main Terminal 1), Terminal 2 = T2 (Main Terminal 2), Terminal 3 = Gate.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (T1) | Main Anode 1 | Primary current path entry point; connected to line side of AC load in common-T2 configurations |
| 2 (T2) | Main Anode 2 / Heat Sink Reference | Current return path and thermal interface; case temperature measured here for derating calculations |
| 3 (Gate) | Trigger Control Input | Sensitive gate requiring ≤5 mA to initiate conduction in any quadrant; referenced to T2 |
Key Features
| Feature | Design Value |
|---|---|
| Three-Quadrant Operation | Enables gate triggering with either polarity of gate-to-T2 voltage, simplifying driver design vs. four-quadrant triacs |
| Planar Passivation | Provides stable leakage current (<1.0 mA IDRM at 125 °C) and long-term reliability in humid environments |
| RoHS & Halogen-Free | Complies with PRSS0003DJ-A environmental spec - no lead, bromine, or chlorine compounds in mold compound or leads |
| Low IGT Consistency | 5 mA max across all quadrants ensures predictable turn-on timing in variable-load AC applications like air cleaner fan stages |
| High Tj Rating | 125 °C maximum junction temperature allows use in compact, thermally constrained appliance PCBs without forced cooling |
Applications
| Washing Machine Motor Control | Air Cleaner Fan Speed Regulation |
|---|---|
Use Scenario: Variable-speed agitation cycle using phase-angle control on universal motor. IC Role / Device Role / Timing Role: Triac acting as AC power switch triggered by microcontroller-generated zero-crossing synchronized pulses. Use Value: Enables precise torque modulation with 0.8 A RMS rating matching typical 60–90 W motor draw, reducing mechanical wear vs. relay-based control. | Use Scenario: Multi-stage fan speed selection in compact indoor air purifiers. IC Role / Device Role / Timing Role: Main AC switching element in random-phase dimming circuit driven by optocoupler-isolated MCU output. Use Value: 5 mA gate sensitivity allows direct drive from low-power optocouplers, eliminating external transistor buffers and saving board space. |
| Solid-State Relay Module | Electric Fan Speed Controller |
Use Scenario: DIN-rail mounted SSR replacing electromechanical relays in HVAC zone dampers. IC Role / Device Role / Timing Role: Output switching device providing galvanically isolated AC load control with zero-crossing detection. Use Value: 700 V VDRM supports global 230/240 VAC mains with safety margin; TO-92 package enables cost-effective through-hole assembly in high-volume SSRs. | Use Scenario: Wall-mounted fan controller with rotary encoder input and multi-tap speed settings. IC Role / Device Role / Timing Role: AC power regulator implementing leading-edge phase control for shaded-pole motor. Use Value: 0.5 V/μs (dv/dt)c rating ensures stable operation with minimal snubber components when driving inductive fan windings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BT134-600E | 600 V VDRM, 4 A IT(RMS), TO-92 package, 5 mA IGT (Q1/Q3 only) | Higher current rating but lower voltage blocking; limited to 230 VAC systems without margin | Select when >0.8 A continuous load current is required and 600 V blocking suffices |
| ON Semiconductor MAC97A6 | 600 V VDRM, 0.8 A IT(RMS), TO-92, 5 mA IGT (Q1/Q2/Q3), 1.5 V VTM | Identical RMS rating and gate sensitivity; slightly higher on-state voltage increases conduction loss | Prefer for legacy designs already qualified with MAC97A6; verify thermal margin due to higher VTM |
Compared with BCR08AM-14A#BD0, BT134-600E offers higher current headroom but reduced voltage safety margin, while MAC97A6 matches RMS rating and gate drive but incurs ~0.5 W extra conduction loss at 0.8 A - impacting thermal design in sealed enclosures.

FAQ
What is the maximum allowable case temperature for continuous operation of BCR08AM-14A#BD0?
The BCR08AM-14A#BD0 is rated for 0.8 A RMS continuous current at Tc = 67 °C, as specified in the Maximum Ratings table. Derating curves on page 4 show allowable RMS current drops to 0.4 A at 100 °C case temperature. Exceeding 67 °C without derating risks exceeding the 125 °C junction limit, especially with 50 °C/W thermal resistance. Always measure Tc at the T2 terminal 1.5 mm from the molded case per datasheet note.
Does BCR08AM-14A#BD0 support triggering in all four quadrants?
No, BCR08AM-14A#BD0 is a three-quadrant triac supporting triggering only in Quadrants I (T2+, G+), II (T2–, G+), and III (T2–, G–). Quadrant IV (T2+, G–) triggering is not characterized or guaranteed. The datasheet explicitly specifies gate trigger parameters only for I, II, and III - confirming intentional three-quadrant design to improve noise immunity and simplify drive circuitry.
Can BCR08AM-14A#BD0 be used without a snubber network?
BCR08AM-14A#BD0 can operate without a snubber for resistive loads or lightly inductive loads where the commutating dv/dt remains below 0.5 V/μs. However, for motor or transformer loads, the datasheet's (dv/dt)c test condition (0.5 V/μs at 125 °C) indicates snubbers are recommended to prevent false triggering during voltage transients. Page 5 shows breakover voltage degrades with rising dv/dt, so snubber selection must ensure actual circuit dv/dt stays within this limit.
What is the meaning of the "#BD0" suffix in BCR08AM-14A#BD0?
The "#BD0" suffix in BCR08AM-14A#BD0 is Renesas' ordering code indicating an active, TO-92 packaged version with plastic bag packing (1000 pcs straight lead form). Per page 7 of the datasheet, #BD0 replaces obsolete #B00 and denotes the current production version - ensuring compatibility with existing TO-92 footprints while guaranteeing RoHS, halogen-free, and Pb-free compliance per PRSS0003DJ-A specification.
How does the gate trigger current of BCR08AM-14A#BD0 vary with junction temperature?
Per page 3's "Gate Trigger Current vs. Junction Temperature" curve, BCR08AM-14A#BD0's IGT increases approximately 2× from 25 °C to 125 °C - e.g., from ~2.5 mA to ~5 mA max. This positive temperature coefficient ensures stable turn-on behavior across the full –40 to +125 °C range. Designers must size gate drive circuits to deliver ≥5 mA at worst-case high temperature, not just room-temperature typical values.
