Product details
Overview
T16M10T800UD from Diodes Incorporated is a glass-passivated, bidirectional silicon thyristor (TRIAC) designed for AC power phase control in mains-connected loads. It features 800V repetitive peak off-state voltage (VDRM/VRRM), 16A RMS on-state current (IT(RMS)), 10mA maximum gate trigger current (IGT1) in Quadrant I, and operates up to +125°C junction temperature. It is used in light dimmers, fan speed controllers, and heating systems requiring reliable zero-crossing–independent triggering.
For engineers reviewing the T16M10T800UD datasheet, T16M10T800UD pinout, T16M10T800UD application, or T16M10T800UD equivalent, key selection criteria include quadrant-triggering behavior, dV/dt immunity (40 V/µs min at TJ = +125°C), thermal resistance (RθJC = 1.9 °C/W), and TO220AB package compatibility with standard heatsinking solutions.
Technical Context
This TRIAC operates in three quadrants (I, II, III) only - excluding Quadrant IV - enabling robust triggering under diverse AC phase conditions while avoiding unreliable gate sensitivity in reverse-conducting modes. Its glass passivation ensures stable VDRM/VRRM performance across temperature and humidity stress.
With a minimum commutating dI/dt rating of 8.5 A/ms and dV/dt capability of 40 V/µs (at TJ = +125°C, gate open), it supports snubberless operation in moderate-noise industrial AC line environments. The internally insulated TO220AB package provides creepage/clearance compliance for reinforced insulation in Class I appliances.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 800 V - Withstands 800V peak AC line transients without conduction; suitable for 230VAC mains with safety margin. |
| IT(RMS) | 16 A - Sustains continuous 16A RMS load current at TJ ≤ +125°C with appropriate heatsinking (RθJC = 1.9 °C/W). |
| IGT1 (Max) | 10 mA - Minimum gate drive required in Quadrant I; enables direct drive from microcontroller GPIO or low-power optocouplers. |
| dV/dt (Min) | 40 V/µs - Resists false turn-on from rapid voltage transients; eliminates need for external snubbers in many 50/60Hz applications. |
| IL1 / IL3 (Max) | 25 / 50 mA - Latching current thresholds define minimum load current needed to sustain conduction after gate pulse removal. |
| RθJC | 1.9 °C/W - Junction-to-case thermal resistance enables predictable thermal design when mounted on finned aluminum heatsinks. |
| TJ Range | −40°C to +125°C - Supports operation in enclosed industrial enclosures and automotive cabin-adjacent environments. |
Pinout & Package
Package: TO220AB (Type WX), molded plastic, lead-free, RoHS-compliant, UL 94V-0 rated. Internally insulated case; matte tin-plated leads solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MT1 (Main Terminal 1) | Anode 1 / Cathode reference | Primary current path terminal; polarity defines TRIAC quadrant behavior during triggering. |
| MT2 (Main Terminal 2) | Anode 2 / Main conduction path | Second main current terminal; voltage polarity between MT2 and MT1 determines conduction direction. |
| G (Gate) | Control input | Triggers conduction in Quadrants I, II, and III only; requires ≥10mA pulse for reliable turn-on at room temperature. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivation | Ensures long-term VDRM stability and resistance to moisture-induced leakage in humid environments. |
| Three-quadrant triggering only | Eliminates Quadrant IV operation, improving noise immunity and reducing risk of unintended turn-on during negative gate pulses. |
| Internally insulated package | Provides reinforced electrical isolation between MT2 and case, enabling safe mounting without insulating hardware in Class I appliances. |
| High dV/dt immunity (40 V/µs) | Supports snubberless operation in 230VAC motor control and heating applications with typical EMI profiles. |
| AEC-Q101 capable process | Manufactured in IATF 16949-certified facilities; qualified for automotive-grade reliability with PPAP support upon request. |

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 BTB16-800BW | Same 16A/800V rating but 35mA IGT max; higher gate drive requirement. | Requires stronger gate driver; less suitable for low-power MCU interfaces. | Select when legacy gate driver circuitry already supports ≥35mA drive. |
| Littelfuse Q6016LH4TP | 16A/600V rating; lower VDRM limits use to 120VAC or derated 230VAC designs. | Not recommended for 230VAC mains without additional overvoltage protection. | Choose only for cost-sensitive 120VAC applications where 600V margin suffices. |
Compared with BTB16-800BW and Q6016LH4TP, T16M10T800UD offers superior gate sensitivity (10mA vs. 35mA/50mA), higher voltage rating (800V vs. 800V/600V), and verified internal insulation - making it optimal for compact, thermally constrained 230VAC consumer appliance designs.

FAQ
What is the maximum gate trigger current required for reliable turn-on?
The T16M10T800UD specifies a maximum gate trigger current (IGT1) of 10 mA under standard test conditions (VAK = 12 V, RL = 100 Ω). This value is measured in Quadrant I and remains valid up to +125°C junction temperature, though IGT increases with temperature per Figure 1 in the datasheet.
Can this TRIAC be used without a snubber circuit?
Yes - its minimum dV/dt rating of 40 V/µs (at TJ = +125°C, gate open) supports snubberless operation in many 50/60 Hz AC control applications, including resistive and lightly inductive loads like heaters and universal motors, provided layout parasitics are minimized.
Is the TO220AB package internally insulated?
Yes - the T16M10T800UD uses an internally insulated TO220AB (Type WX) package, meaning the metal tab (MT2) is electrically isolated from the die. This allows direct mounting to grounded heatsinks without additional insulating hardware in Class I appliance designs.
How does the latching current vary with temperature?
Latching current (IL1) increases with junction temperature: typical values range from ~25 mA at 25°C to ~50 mA at +125°C (per Figure 3). Designers must ensure minimum load current exceeds IL at worst-case operating temperature to maintain conduction after gate pulse removal.
