Product details
Overview
T16M35T800UB from Diodes Incorporated is a glass-passivated, lead-free, halogen-free TRIAC rated for 800V repetitive peak off-state voltage (VDRM/VRRM), 16A RMS on-state current (IT(RMS)), and 35mA maximum gate trigger current (IGT) in Quadrants I, II, and III. It operates up to +125°C junction temperature and is used in AC motor speed control, heating element regulation, and resistive load dimming circuits.
For engineers reviewing the T16M35T800UB datasheet, T16M35T800UB pinout, T16M35T800UB application, or T16M35T800UB equivalent, key selection criteria include verified dV/dt immunity (2000 V/µs at TJ = +125°C), latching current (IL3 ≤ 50 mA), holding current (IH3 ≤ 50 mA), and TO220AB thermal resistance (RθJC = 1.4 °C/W).
Technical Context
This bidirectional thyristor supports phase-angle control in AC line-powered systems with three-quadrant triggering only-excluding Quadrant IV-ensuring predictable turn-on behavior under both positive and negative half-cycles. Its glass passivation enhances voltage ruggedness and long-term reliability in high-noise industrial environments.
The device delivers 130A non-repetitive surge capability (t = 16.7ms, 60Hz), an I²t rating of 84.5 A²s for fuse coordination, and a minimum dI/dt rating of 8.5 A/ms without snubber, enabling robust commutation in inductive loads like universal motors and solenoids.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 800 V - Withstands 800V peak reverse/forward blocking voltage before conduction, suitable for 230VAC mains with safety margin. |
| IT(RMS) | 16 A - Sustains continuous 16A RMS current at TJ = +125°C, supporting medium-power AC loads (e.g., 3.5 kW resistive). |
| IGT (max) | 35 mA - Maximum gate trigger current required in Quadrant III, defining minimum driver strength needed for reliable turn-on. |
| dV/dt (min) | 2000 V/µs - Minimum rate-of-rise of off-state voltage at TJ = +125°C, preventing false triggering in noisy AC environments. |
| RθJC | 1.4 °C/W - Junction-to-case thermal resistance enables efficient heatsink coupling; 16A operation requires ≤ 22.4°C temperature rise across case interface. |
| IL3 / IH3 | 50 mA / 50 mA - Latching and holding currents at worst-case conditions ensure stable conduction after gate pulse removal. |
Pinout & Package
Package: TO220AB (Type WX), molded plastic, matte tin-plated leads, UL 94V-0 rated, 2.08 g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MT1 (Main Terminal 1) | Anode for forward conduction; cathode for reverse conduction | Primary current path terminal-must be connected to load return side in standard phase-control topology. |
| MT2 (Main Terminal 2) | Cathode for forward conduction; anode for reverse conduction | Main power input terminal-typically tied to AC line or neutral depending on circuit configuration. |
| G (Gate) | Control electrode for triggering conduction | Receives low-energy pulse to initiate bidirectional conduction; referenced to MT1 in all quadrants. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivation | Enables stable VDRM/VRRM performance over lifetime and humidity exposure, critical for outdoor or humid-environment controls. |
| Three-quadrant triggering only | Eliminates Quadrant IV operation, reducing susceptibility to false turn-on from noise-induced gate coupling during negative MT2–positive MT1 transitions. |
| High dV/dt immunity (2000 V/µs) | Supports direct connection to noisy AC lines (e.g., motor back-EMF, relay switching) without external snubbers in many applications. |
| AEC-Q101 readiness | Manufactured in IATF 16949-certified facilities with PPAP capability-enables qualification for automotive HVAC blower and seat heater modules. |
Applications
| AC Motor Speed Control | Resistive Load Dimming |
|---|---|
Use Scenario: Variable-speed control of universal motors in power tools (e.g., electric drills, sanders) using phase-angle firing. IC Role / Device Role / Timing Role: Bidirectional AC switch triggered by zero-crossing synchronized gate pulses to regulate average power delivered to motor winding. Use Value: Enables smooth torque control with 16A IT(RMS) handling stall currents up to 130A surge, while glass passivation ensures longevity under mechanical vibration. |
Use Scenario: Brightness adjustment of incandescent/halogen lamps in residential lighting systems. IC Role / Device Role / Timing Role: Main AC switching element in leading-edge dimmer circuits, gated by microcontroller-driven optocoupler. Use Value: 800V VDRM accommodates 230VAC mains with 2× safety margin; 35mA IGT allows direct drive from common logic-level optocouplers (e.g., MOC3023). |

IC Role / Device Role / Timing Role: Solid-state relay replacement for ON/OFF or phase-controlled thermal regulation. Use Value: 125°C max TJ and 1.4 °C/W RθJC allow compact heatsinking in space-constrained appliances; RoHS/Green compliance meets global regulatory requirements. |
Use Scenario: Speed modulation of AC induction fans in HVAC blowers and kitchen exhaust systems. IC Role / Device Role / Timing Role: Line-synchronized AC switch controlling RMS voltage applied to fan winding. Use Value: Three-quadrant triggering ensures consistent turn-on timing across AC half-cycles, minimizing audible hum and torque ripple in fan operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TRIAC-based AC power control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BTB16-800CW | Same TO220AB package, 16A/800V rating, but 50mA IGT (Quadrant I/II/III), lower dV/dt (1000 V/µs). | Requires stronger gate drive; less robust in high-dV/dt environments (e.g., motor commutation noise). | Prefer when gate driver has ≥50mA sourcing capability and system noise is low. |
| Littelfuse Q6016LH4 | TO220AB, 16A/600V rating, 35mA IGT, but lower VDRM/VRRM limits use to 120VAC or 230VAC with derating. | Not suitable for full 230VAC mains without voltage margin compromise; higher IH (60mA) risks dropout at high temperature. | Select only for 120VAC systems or where 600V blocking suffices and cost is primary constraint. |
Compared with BTB16-800CW and Q6016LH4, T16M35T800UB offers superior dV/dt immunity (2000 V/µs vs. 1000/- V/µs) and full 800V blocking margin for 230VAC, making it optimal for noise-prone industrial and appliance motor controls where reliability trumps marginal cost savings.

FAQ
What is the maximum junction temperature and how does it affect thermal design?
The T16M35T800UB has a maximum junction temperature (TJ) of +125°C. With RθJC = 1.4 °C/W, a 16A RMS load generating ~25.6W conduction loss (VT ≈ 1.6V) requires ≤17.7°C rise from case to junction-so heatsink selection must keep case temperature ≤107.3°C under worst-case ambient and airflow conditions.
Can this TRIAC be used in Quadrant IV, and why is it excluded?
No, the T16M35T800UB is specified for triggering in Quadrants I, II, and III only. Quadrant IV (MT2 negative, gate positive relative to MT1) is intentionally disabled to prevent erratic turn-on caused by capacitive coupling or noise in high-dV/dt applications-improving system predictability and EMI resilience.
What gate drive circuitry is recommended for reliable triggering?
A logic-level optocoupler (e.g., MOC3023) with ≥35mA peak output current into a 100Ω load is sufficient for Quadrant I/II/III triggering. For improved noise immunity, add a 100Ω series gate resistor and 0.01µF capacitor from gate to MT1, per Diodes' application guidance in AN-4001.
Is this part qualified for automotive applications?
While not pre-qualified to AEC-Q101, the T16M35T800UB is manufactured in IATF 16949-certified facilities, supports PPAP documentation, and meets all electrical and environmental specs required for automotive cabin applications (e.g., HVAC blower control); formal qualification requires customer-specific testing and validation.
