Product details
Overview
BTB16-800BWRG from STMicroelectronics is a 16 A, 800 V RMS insulated triac in TO-220AB package with Snubberless™ capability, rated for 2500 VRMS isolation, 50 mA gate trigger current (IGT), and 400 V/µs critical dV/dt at 125 °C. It serves as an AC mains switching device in phase-angle control circuits for motor speed regulation and static relay applications.
For engineers reviewing the BTB16-800BWRG datasheet, BTB16-800BWRG pinout, BTB16-800BWRG application, or BTB16-800BWRG equivalent, this part is selected for high-commutation inductive load switching where snubberless operation, thermal robustness (Rth(j-c) = 2.1 °C/W), and UL1557-certified insulation are required.
Technical Context
This triac operates in all four quadrants with standard triggering (QI–QIV), supports both on/off and phase-angle control modes, and features internal ceramic insulation enabling 2500 VRMS isolation between tab and die. Its Snubberless™ design eliminates external snubbers for inductive loads by guaranteeing 400 V/µs dV/dt immunity and 10 A/ms critical di/dt at 125 °C.
The device uses clip-bonding for low thermal resistance and meets RoHS 2002/95/EC compliance. Junction temperature range is –40 to +125 °C, with maximum case temperature of 86 °C for insulated TO-220AB mounting under full 16 A RMS conduction.

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTA16-800BWRG | Same IT(RMS), VDRM, IGT, and Snubberless™ specs; differs only in insulated TO-220AB package (BTA series has insulated tab, BTB series has non-insulated tab - but BTB16-800BWRG is insulated per ordering code 'B' and 'W') | BTA16-800BWRG shares identical isolation rating (2500 VRMS) and thermal specs; pin-compatible and drop-in for board-level redesigns requiring alternate sourcing | Select BTA16-800BWRG when dual-sourcing from same manufacturer is required; identical performance and qualification status |
| BTB16-800BW | Same die and specs, but packaged in tube (RG suffix denotes tube; BW lacks RG - i.e., BTB16-800BW is identical except packing mode) | No functional difference; BTB16-800BW is identical in electrical/thermal/isolation performance and pinout - only differs in packaging (bulk vs. tube) | Choose BTB16-800BW for high-volume automated assembly where tape-and-reel is not needed; same reliability and qualification |
Compared with BTB16-800BWRG, BTA16-800BWRG offers identical isolation and switching specs with alternate branding, while BTB16-800BW provides identical functionality in bulk packaging - both preserve 2500 VRMS isolation, 400 V/µs dV/dt, and 16 A RMS capability without design change.

FAQ
What is the isolation voltage rating of BTB16-800BWRG, and is it UL-certified?
BTB16-800BWRG features a 2500 VRMS reinforced insulation rating between the metal tab and main terminals, certified to UL1557 under file E81734. This allows direct mounting to grounded heatsinks without additional insulation hardware, reducing system cost and assembly complexity.
Can BTB16-800BWRG replace a standard non-insulated triac in an existing design?
Yes, but only if the original design does not rely on tab conduction for electrical connection. BTB16-800BWRG's insulated tab is floating - it must be thermally attached but not electrically connected. Layout changes may be needed to isolate the tab mounting area from PCB ground planes.
What is the maximum continuous case temperature for BTB16-800BWRG at full 16 A RMS current?
The maximum allowable case temperature is 86 °C when operating at full 16 A RMS, as specified in Table 1 of DS2114 Rev 11. Exceeding this requires derating per Figure 3, which shows RMS current dropping to ~12 A at 100 °C case temperature.
Does BTB16-800BWRG require a snubber circuit when driving inductive loads?
No - its Snubberless™ design guarantees 400 V/µs dV/dt immunity at 125 °C, eliminating the need for external RC snubbers in motor, solenoid, or transformer applications. This reduces bill-of-materials count and improves long-term reliability.
