Product details
Overview
MAC97A8/DG,412 from NXP Semiconductors is a planar passivated 4-quadrant triac in TO-92 (SOT54) package, designed for direct interfacing with microcontrollers and logic ICs. It delivers 600 V repetitive peak off-state voltage, 0.6 A RMS on-state current, and gate trigger current as low as 1 mA in T2+ G+ quadrant - enabling low-power phase control in compact AC load switching applications.
For engineers reviewing the MAC97A8/DG,412 datasheet, MAC97A8/DG,412 pinout, MAC97A8/DG,412 application, or MAC97A8/DG,412 equivalent, key selection criteria include four-quadrant triggering capability, sub-5 mA maximum IGT across all quadrants, thermal resistance of 60 K/W (junction-to-lead), and compatibility with through-hole PCB assembly for solid-state relay and appliance control designs.
Technical Context
This 4Q triac uses planar passivation to ensure voltage ruggedness and stable blocking behavior up to 600 V. Its symmetric gate sensitivity enables reliable turn-on in all four quadrants without external polarity conditioning circuitry.
The device supports full-sine-wave conduction with RMS current up to 0.6 A at lead temperature ≤50 °C and withstands non-repetitive surge currents up to 8 A (20 ms). Critical dV/dt immunity reaches 45 V/µs at 110 °C, minimizing false triggering in noisy AC environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 600 V - ensures reliable blocking of standard 230 VAC mains with safety margin |
| IT(RMS) | 0.6 A - supports continuous AC load switching up to ~138 W at 230 VAC |
| IGT (T2+ G+) | 1–5 mA - enables direct drive from 3.3 V/5 V GPIO without buffer stage |
| dV/dt (min) | 30 V/µs - suppresses false triggering in inductive or noisy line environments |
| Rth(j-lead) | 60 K/W - allows thermal management via PCB copper pour or heatsinked leads |
| VT | 1.4–1.9 V - limits conduction loss to <1.6 W at 0.85 A, reducing self-heating |
| IH | 1–10 mA - ensures stable latching after gate pulse removal under light loads |
Pinout & Package
MAC97A8/DG,412 is housed in a plastic single-ended leaded TO-92 (SOT54) package with 3 through-hole leads. The package measures 4.8 × 4.2 × 14.5 mm (D × E × L) and features 2.54 mm lead pitch for standard PCB layout compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | T2 | Main terminal 2 - connects to AC line (hot) side; carries full load current |
| 2 | G | Gate - receives low-current trigger signal; polarity-insensitive due to 4Q operation |
| 3 | T1 | Main terminal 1 - connects to AC neutral/load return; completes conduction path |
Key Features
| Feature | Design Value |
|---|---|
| Four-quadrant triggering | Enables gate control with either polarity on T2/G or T1/G - eliminates need for external diode networks |
| Very sensitive gate | IGT ≤ 5 mA in all quadrants - compatible with 3.3 V MCU outputs and open-collector logic drivers |
| Planar passivation | Provides consistent VDRM stability and long-term reliability under thermal cycling and humidity stress |
| High dV/dt immunity | 45 V/µs typical at 110 °C - prevents spurious turn-on during zero-crossing transients or EMI events |
| Low holding current | IH ≤ 10 mA - maintains conduction down to very light loads (e.g., LED drivers, small solenoids) |
Applications
| Smart Appliance Control | LED Dimming Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4Q triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BT134-600E | Same TO-92 package; higher IT(RMS) = 4 A but requires ≥10 mA IGT; no T2+ G+ quadrant spec | Better for higher-power loads (>100 W); less suitable for direct 3.3 V MCU drive | Choose when load current exceeds 0.6 A and gate drive strength is ≥10 mA |
| ON Semiconductor MAC97A6 | Identical pinout and package; lower VDRM = 400 V; IGT max 10 mA in T2− G+ | Limited to 120 VAC systems; reduced noise immunity due to lower dV/dt rating | Choose only for cost-sensitive 120 VAC applications where 600 V margin is unnecessary |
Compared with BT134-600E and MAC97A6, MAC97A8/DG,412 uniquely balances ultra-low gate drive (≤5 mA), full 4Q symmetry, and 600 V blocking - making it optimal for space-constrained, low-power AC control where MCU GPIO directly drives the gate without level-shifting.

FAQ
What is the maximum RMS on-state current rating for MAC97A8/DG,412?
The MAC97A8/DG,412 has an RMS on-state current rating of 0.6 A under full sine-wave conditions with lead temperature ≤50 °C. This corresponds to approximately 138 W at 230 VAC and defines the continuous power-handling limit before thermal derating becomes necessary.
Does MAC97A8/DG,412 support triggering in all four quadrants?
Yes, MAC97A8/DG,412 is explicitly specified as a 4Q triac with verified gate trigger current values in all four quadrants: T2+ G+, T2+ G−, T2− G−, and T2− G+. Its symmetric gate sensitivity eliminates the need for external polarity conditioning circuitry.
What is the gate trigger voltage range for MAC97A8/DG,412?
The gate trigger voltage (VGT) for MAC97A8/DG,412 is specified as 0.1–0.7 V at VD = 400 V, IT = 0.1 A, and Tj = 110 °C. This low threshold ensures reliable turn-on even with weak gate drive sources or elevated junction temperatures.
Can MAC97A8/DG,412 be used with 3.3 V microcontrollers?
Yes, MAC97A8/DG,412 can be driven directly by 3.3 V microcontrollers: its maximum gate trigger current is 5 mA in the most sensitive quadrant (T2+ G+), and VGT remains ≤0.7 V at high temperature - well within typical GPIO sink/source capability.
What is the thermal resistance from junction to lead for MAC97A8/DG,412?
The thermal resistance from junction to lead (Rth(j-lead)) for MAC97A8/DG,412 is 60 K/W under full-cycle conditions. This value enables effective heat transfer to PCB copper or external heatsinks via the TO-92 leads, supporting sustained operation at rated current.
