Product details
Overview
T16M5T600B from Littelfuse (LSC) is a sensitive-gate, 16A RMS, 600V bidirectional thyristor (TRIAC) designed for AC phase-control switching in mains-powered loads. It features uniform gate triggering across quadrants Q1–Q3, 2.0mA max IGT1, 1.8V max VTM at ±21A peak, and operates from –40°C to +150°C junction temperature - enabling direct microcontroller-driven dimming and motor speed control in industrial lighting and HVAC actuators.
For engineers reviewing the T16M5T600B datasheet, T16M5T600B pinout, T16M5T600B application, or T16M5T600B equivalent, key selection criteria include quadrant-triggering consistency, 120A non-repetitive surge rating, thermal resistance RthJC = 2.0°C/W, and compliance with industrial-grade thermal derating curves up to 70°C case temperature.
Technical Context
This TRIAC implements bidirectional conduction via MT1–MT2 terminals and uses a sensitive gate structure enabling reliable turn-on with low-current drive (≤5mA IGT across all quadrants). Its blocking capability is rated at 600V VDRM/VRRM with ≤2.0mA IDRM/IRRM at 110°C, supporting robust operation under noisy AC line conditions.
Dynamic performance includes dv/dt immunity of ≥25V/μs (typ. 75V/μs) and di/dt(c) ≥8.0A/ms, ensuring stable commutation in inductive loads like fans and solenoids without snubber networks in many designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 600 V - Sustains full AC line voltage (e.g., 230VAC RMS with 2× safety margin) without conduction. |
| IT(RMS) | 16 A @ TC = 70°C - Supports continuous load current up to 16A with heatsink mounting. |
| ITSM | 120 A - Withstands single half-cycle surges (e.g., motor startup inductance kickback). |
| IGT1 / IGT2 / IGT3 | ≤5.0 mA - Gate trigger current low enough for direct GPIO driving (e.g., STM32, ESP32) without buffer. |
| VTM | ≤1.8 V @ ±21A - Low on-state loss (~38W max conduction power), reducing heatsink requirements. |
| RthJC | 2.0 °C/W - Enables precise junction temperature estimation when mounted to heatsink. |
| dv/dt (min) | 25 V/μs - Resists false triggering from EMI or fast transients on AC lines. |
Pinout & Package
Package: TO-220AB - Molded plastic case, 2.0g weight, designed for vertical heatsink mounting with insulated washer or clip.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Main Terminal 1 (MT1) | Reference terminal for gate trigger polarity; common return path for AC load current. |
| 2 | Main Terminal 2 (MT2) | Primary current-carrying terminal; polarity defines quadrant conduction behavior. |
| 3 | Gate (G) | Sensitive control input; triggers conduction when voltage/current exceeds IGT/VGT thresholds in any quadrant. |
| 4 | Main Terminal 2 (MT2) | Duplicate MT2 connection for mechanical stability and lower thermal resistance path in TO-220AB package. |
Key Features
| Feature | Design Value |
|---|---|
| Quadrant-uniform gate sensitivity | IGT ≤5.0mA and VGT ≤1.5V across Q1/Q2/Q3 - eliminates need for external gate polarity reversal circuitry. |
| High surge current rating | ITSM = 120A - supports repeated inrush events (e.g., transformer energization, compressor startup) without degradation. |
| Pb-free TO-220AB package | RoHS-compliant, 260°C solderability - compatible with lead-free reflow and manual assembly processes. |
| Thermal derating curve support | Rated 16A RMS at TC = 70°C, linearly derated to zero at TC = 110°C - enables accurate thermal design using Fig.1 in datasheet. |
Applications
| Industrial Lighting Control | AC Motor Speed Regulation |
|---|---|
Use Scenario: Phase-angle dimming of 230VAC halogen and LED driver inputs in factory floor lighting panels. IC Role / Device Role / Timing Role: Bidirectional AC switch triggered by zero-crossing synchronized PWM from MCU.

IC Role / Device Role / Timing Role: Synchronized AC switch enabling capacitor insertion/removal at zero-voltage crossing. Use Value: Quadrant Q3 triggering capability supports reverse-conduction timing; IL ≤20mA ensures reliable latching even at elevated junction temperatures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TRIAC switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BTB16-600CW | Same 16A/600V rating; IGT1 = 10mA (higher than T16M5T600B's 5mA max); TO-220 package with isolated tab. | Requires higher gate drive current; better suited for optocoupler-isolated gate circuits. | Select when isolation between heatsink and MT2 is mandatory; avoid if driving directly from low-current MCU pins. |
| ON Semiconductor MAC16M | 16A/600V; IGT1 = 15mA; no Q2/Q3 IGT spec provided; RthJC = 2.5°C/W (higher thermal resistance). | Limited quadrant specification reduces predictability in asymmetric AC waveforms. | Prefer only in cost-sensitive, non-critical dimming where gate drive margin is ample and thermal headroom exists. |
Compared with BTB16-600CW and MAC16M, the T16M5T600B offers superior gate sensitivity (≤5mA IGT), verified Q1–Q3 uniformity, and lower thermal resistance - making it optimal for space-constrained, microcontroller-direct, and thermally demanding industrial controls.

FAQ
What is the maximum allowable case temperature for continuous 16A RMS operation?
The T16M5T600B is rated for 16A RMS only at TC = 70°C, as shown in Fig.1 of the datasheet. Operation above this temperature requires linear derating - e.g., 12A at 90°C, 0A at 110°C. Exceeding 70°C case temperature without derating risks thermal runaway due to positive temperature coefficient of on-state voltage.
Can the T16M5T600B be driven directly by an ESP32 GPIO pin?
Yes - its IGT1 ≤5.0mA and VGT1 ≤1.5V allow direct drive from ESP32 GPIO (3.3V, 40mA sink/source). Use a 220Ω series resistor to limit gate current to ~10mA peak and ensure clean turn-on. Avoid floating gate; always tie G to MT1 via ≥10kΩ pull-down when inactive.
Is heatsinking required for 10A RMS operation at 25°C ambient?
Yes - even at 10A RMS, power dissipation exceeds 10W (VTM × IT ≈ 1.8V × 10A × 0.5 duty ≈ 9W). With RthJC = 2.0°C/W and typical RthCH ≈ 1.5°C/W, junction temperature would exceed 125°C without a heatsink. A minimum 5°C/W heatsink is recommended for sustained 10A operation.
Does the T16M5T600B support gate triggering in Quadrant IV?
No - the datasheet explicitly states "All polarities are reference to MT1, with in-phase signal… quadrants I and III are used." Q4 (MT2 negative, gate positive relative to MT1) is not characterized or guaranteed. Design must restrict triggering to Q1 (MT2+, G+), Q2 (MT2–, G+), and Q3 (MT2–, G–) per Fig.7–Fig.8 curves.
