Product details
Overview
ACT108-600E from NXP Semiconductors is an AC thyristor power switch in SOT54 (TO-92) package, designed for low-to-medium power AC load control with self-protective transient suppression. It delivers 600 V repetitive peak off-state voltage, 0.8 A RMS on-state current, and exclusive negative gate triggering for robust noise immunity in inductive/resistive motor circuits.
For engineers reviewing the ACT108-600E datasheet, ACT108-600E pinout, ACT108-600E application, or ACT108-600E equivalent, this device serves as a self-protected, gate-isolated AC switching solution for fan and pump motor control where dV/dt immunity (>1000 V/µs), clamping voltage (650 V), and high-energy transient turn-on behavior are critical selection criteria.
Technical Context
The ACT108-600E operates as a three-terminal AC thyristor with common (CM), load (LD), and gate (G) terminals. Its negative gate triggering enables full-cycle conduction while isolating gate drive circuitry from load current transients. The device integrates intrinsic overvoltage protection via safe clamping at 650 V and self-protective turn-on during high-energy surges per IEC 61000-4-5.
It exhibits 1000 V/µs dV/dt immunity at 125 °C with gate open, latching current ≤30 mA, holding current 9–25 mA, and on-state voltage ≤1.3 V at 1.1 A. Thermal resistance junction-to-lead is 60 K/W with heatsink compound, supporting reliable operation up to 125 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 600 V - maximum repetitive off-state voltage; ensures safe blocking across standard 230 V AC mains with margin. |
| IT(RMS) | 0.8 A - continuous RMS current rating at Tlead ≤71 °C; supports fan/pump motors up to ~180 W resistive or inductive loads. |
| dV/dt | 1000 V/µs - minimum rate-of-rise immunity with gate open at 125 °C; prevents false triggering in noisy industrial environments. |
| VCL | 650 V - clamping voltage at 100 µA, 1 ms pulse; limits transient energy without external snubbers. |
| VPP | 2 kV - non-repetitive peak pulse voltage rating; meets IEC 61000-4-5 surge immunity requirements. |
| IGT | 1–10 mA - gate trigger current range at 12 V, 100 mA load; enables direct drive from microcontrollers or optocouplers. |
| Rth(j-lead) | 60 K/W - thermal resistance junction-to-lead with heatsink compound; allows PCB-level thermal management without dedicated heatsinks. |
Pinout & Package
SOT54 (TO-92) plastic single-ended leaded through-hole package with 3 leads; compact 5.2 × 4.8 × 14.5 mm outline per IEC/JEDEC SC-43A standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - CM | Common terminal | Reference node for gate drive; connects to neutral or common return path in AC line-switching topologies. |
| 2 - G | Gate | Negative-trigger input; enables full-cycle conduction with isolated gate driver design and high noise immunity. |
| 3 - LD | Load terminal | AC load connection point; carries full RMS current and withstands 600 V blocking; electrically separated from gate path. |
Key Features
| Feature | Design Value |
|---|---|
| Exclusive negative gate triggering | Enables gate drive decoupling from load current path, eliminating ground loop interference in motor control circuits. |
| Self-protective turn-on during high-energy transients | Activates conduction under surge conditions (e.g., IEC 61000-4-5 2 kV pulses), diverting energy and preventing downstream component damage. |
| Safe clamping of low-energy over-voltage transients | Maintains 650 V clamping limit at 100 µA, suppressing fast spikes without external TVS diodes or RC snubbers. |
| Very high noise immunity | Validated 1000 V/µs dV/dt immunity and <10 mA gate trigger current ensure stable operation in EMI-heavy environments like HVAC or appliance control. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar AC thyristor switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BT134-600E | Same SOT54 package, 4 A RMS rating, no integrated clamping; requires external snubber for >500 V/µs dV/dt. | Higher current capacity but lacks self-protective turn-on and 650 V clamping; suitable only where external protection is acceptable. | Select BT134-600E only if higher RMS current (4 A vs. 0.8 A) is required and board space permits snubber components. |
| MAC97A6 | TO-92 package, 0.8 A RMS, 600 V VDRM, but positive gate triggering and no clamping function. | No transient self-protection; lower noise immunity due to positive gate architecture and 500 V/µs dV/dt rating. | Choose MAC97A6 only for cost-sensitive, low-noise environments where surge immunity is managed externally. |
Compared with BT134-600E and MAC97A6, the ACT108-600E uniquely combines negative gate triggering, 650 V clamping, and self-protective turn-on-enabling simplified, snubberless designs for safety-critical and EMI-prone AC motor control where reliability under surge stress is mandatory.

FAQ
What is the maximum RMS current rating for the ACT108-600E?
The ACT108-600E has a maximum RMS on-state current (IT(RMS)) of 0.8 A under full sine-wave conditions with lead temperature ≤71 °C. This rating assumes proper PCB thermal management and is validated per Figure 2 in the datasheet. Exceeding this value risks thermal runaway or premature failure, especially at elevated ambient temperatures.
Does the ACT108-600E require an external snubber circuit?
No, the ACT108-600E does not require an external snubber due to its integrated 650 V clamping voltage (VCL) and self-protective turn-on behavior during high-energy transients. Its 1000 V/µs dV/dt immunity further reduces false triggering risk. Snubbers may still be added for extreme EMI mitigation but are not necessary for basic surge compliance per IEC 61000-4-5.
What is the gate trigger polarity requirement for the ACT108-600E?
The ACT108-600E uses exclusive negative gate triggering: the gate must be driven negative relative to the common (CM) terminal to initiate conduction. This architecture isolates the gate driver from load current effects and provides superior noise immunity compared to positive-trigger devices. Gate trigger current ranges from 1 mA to 10 mA at 12 V.
Can the ACT108-600E replace a mechanical relay in fan control applications?
Yes, the ACT108-600E is commonly used as a solid-state relay replacement in fan motor circuits. It supports full-cycle AC conduction, handles inductive kickback inherently, and offers 2 kV non-repetitive peak pulse voltage tolerance. Unlike mechanical relays, it provides silent operation, infinite cycle life, and faster switching-provided heat dissipation and gate drive meet datasheet specifications.
What is the thermal resistance from junction to ambient for the ACT108-600E?
The ACT108-600E has a typical junction-to-ambient thermal resistance (Rth(j-a)) of 150 K/W when mounted on a printed-circuit board with 4 mm lead length. This value assumes standard FR-4 board material and no heatsink. For sustained 0.8 A operation, PCB copper area and airflow must be optimized to keep junction temperature below 125 °C.
