Product details
Overview
T16M35T800HC from LSC is a 16 A RMS, 800 V bidirectional thyristor (triac) designed for AC phase-control switching in mains-powered loads. It features three-quadrant triggering, isolated mounting base (ITO-220AB), 1.3 V typical on-state voltage at ±16 A peak, and 500 V/μs critical dv/dt rating at 150°C junction temperature. Used in solid-state relays, motor speed controllers, and lighting dimmers.
For engineers reviewing the T16M35T800HC datasheet, T16M35T800HC pinout, T16M35T800HC application, or T16M35T800HC equivalent, key selection criteria include blocking voltage (800 V), RMS current rating (16 A), gate trigger current (≤35 mA), thermal resistance (4.3 °C/W junction-to-heatsink), and isolated package compliance for high-voltage isolation requirements.
Technical Context
This triac operates in quadrants I and III with in-phase AC line signals and supports full-cycle sine-wave conduction at 60 Hz. Its passivated die ensures stable blocking characteristics across -40°C to +150°C junction temperature range, and low-level gate drive enables compatibility with microcontroller GPIOs via simple RC networks.
The device uses an isolated mounting base (ITO-220AB) to eliminate need for insulating hardware when mounted to heatsinks. Its 93 A²s I²t rating supports robust surge immunity against single-cycle 150 A surges, while 2500 VAC dielectric strength between terminals and case meets industrial isolation standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Blocking Voltage | 800 V - Withstands peak AC line voltages up to 566 V RMS (e.g., 400 VAC industrial systems) without conduction. |
| RMS Current Rating | 16 A at TC = 80°C - Supports continuous load switching of ~3.5 kW resistive loads at 230 VAC with proper heatsinking. |
| Gate Trigger Current | ≤35 mA - Compatible with standard logic-level drivers (e.g., ULN2003, optocouplers like MOC3021) without external amplification. |
| Junction-to-Heatsink Rθ | 4.3 °C/W - Enables thermal design for ≤14 W power dissipation at 150°C max junction temperature with 80°C case temp. |
| Critical dv/dt | 500 V/μs at TJ = 150°C - Resists false triggering from fast transients in noisy industrial environments without snubber circuits. |
| Isolation Voltage | 2500 VAC - Provides reinforced insulation between power terminals and heatsink-mounting surface per IEC 60747-6. |
| Holding Current | 3–50 mA - Ensures reliable turn-off after zero-crossing in low-power loads (e.g., LED drivers, small solenoids). |
Pinout & Package
Package: ITO-220AB - Molded plastic case with electrically isolated metal tab (mounting base), 1.625 g weight, compliant with JEDEC TO-220 mechanical outline but with enhanced creepage/clearance for 800 V applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Main Terminal 1 (MT1) | Reference terminal for gate triggering polarity; defines quadrant I/III operation relative to MT2. |
| 2 | Main Terminal 2 (MT2) | High-side AC line or load connection point; carries full load current during conduction. |
| 3 | Gate (G) | Control input requiring ≤35 mA pulse to initiate conduction; referenced to MT1 for triggering sensitivity. |
Key Features
| Feature | Design Value |
|---|---|
| Three-quadrant triggering | Enables gate control only in quadrants I and III, reducing susceptibility to false triggering from noise on MT2. |
| Passivated die | Ensures long-term parameter stability and uniform leakage current (<5 µA @ 25°C) across production lots and temperature extremes. |
| Isolated mounting base | Eliminates need for mica washers or silicone pads-direct bolt-down to grounded heatsink with 2500 VAC isolation integrity. |
| Low holding current | 3 mA minimum allows reliable commutation in low-current AC loads (e.g., pilot lamps, indicator circuits) without latch-up. |
| High dv/dt immunity | 500 V/μs rating at 150°C permits use in variable-frequency drives and SCR-controlled rectifiers without added snubbers. |
Applications
| AC Motor Speed Control | Industrial Lighting Dimming |
|---|---|
Use Scenario: Phase-angle control of single-phase induction motors in HVAC blowers and conveyor drives. IC Role / Device Role / Timing Role: Bidirectional AC switch triggered near zero-crossing to regulate average power delivered to motor windings. Use Value: Enables smooth torque control without audible whine; 16 A rating supports motors up to 2.2 kW at 230 VAC. | Use Scenario: Dimming of high-intensity discharge (HID) and incandescent lamps in factory lighting systems. IC Role / Device Role / Timing Role: Main power switching element in leading-edge dimmer circuits synchronized to AC line zero-crossing. Use Value: 800 V blocking withstands transient overvoltages on unregulated industrial mains; isolated base simplifies EMI-filtered enclosure design. |
| Solid-State Relay (SSR) | Heating Element Control |
Use Scenario: Replacement for electromechanical relays in PLC output modules controlling 240 VAC resistive loads. IC Role / Device Role / Timing Role: Output-stage triac providing galvanically isolated, bounce-free switching of AC loads. Use Value: 150 A non-repetitive surge rating handles inrush currents of transformers and solenoids; 4.3 °C/W RthJC supports compact SSR form factors. | Use Scenario: Temperature-regulated heating in industrial ovens and plastic extruders using PID-controlled AC power cycling. IC Role / Device Role / Timing Role: Power switch modulated by zero-crossing SSR driver to deliver precise duty-cycle-controlled energy to resistive heaters. Use Value: Low 1.3 V on-state voltage minimizes self-heating at 16 A, improving thermal stability in closed-loop temperature control systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BTB16-800CW | Same 16 A/800 V rating, but 4-pin TO-220 package with insulated tab; higher IGT (50 mA max) and lower dv/dt (250 V/μs). | Requires identical heatsink isolation but less noise-immune in high-dv/dt environments. | Prefer when legacy ST ecosystem support or dual-gate variants are needed. |
| ON Semiconductor Q6016LH4 | 16 A/600 V rating, 3-pin ITO-220AB, 35 mA IGT, but lower blocking voltage limits use to 277 VAC systems. | Not suitable for 400 VAC industrial lines or surge-prone 800 V applications. | Select only for cost-sensitive 240–277 VAC lighting or appliance designs. |
Compared with BTB16-800CW and Q6016LH4, T16M35T800HC offers superior 800 V blocking margin and 500 V/μs dv/dt immunity-critical for reliability in 400 VAC industrial mains and noisy factory floor environments-while maintaining identical pinout and thermal interface.

FAQ
What is the maximum allowable case temperature for continuous 16 A operation?
The datasheet specifies 16 A RMS current at TC = 80°C. Exceeding this requires derating per Figure 7: at 100°C case temperature, maximum RMS current drops to ~12 A. Thermal design must ensure heatsink interface resistance and ambient conditions maintain TC ≤ 80°C under full load.
Does T16M35T800HC require a heatsink in all applications?
Yes-its 4.3 °C/W RthJC and 14 W typical power dissipation at 16 A necessitate a heatsink for any continuous operation above ~2 A. Without heatsinking, junction temperature exceeds 150°C within seconds, risking thermal runaway and failure.
Can this triac be used with zero-crossing optocouplers like MOC3041?
Yes-its ≤35 mA gate trigger current and 0.9 V typical gate trigger voltage match MOC3041's 15–50 mA output capability. The triac's three-quadrant operation also avoids false triggering common with random-phase optocouplers in sensitive control loops.
Is the ITO-220AB package truly isolated, and what is its creepage distance?
Yes-the ITO-220AB package provides 2500 VAC isolation between terminals and mounting base. While exact creepage isn't specified in the datasheet, the molded plastic body and recessed leadframe meet ≥8 mm creepage per IEC 60664-1 for Pollution Degree 2, validated by the 2500 VAC dielectric test.
