Product details
Overview
T2535-600G from STMicroelectronics is a 25 A RMS, 600 V repetitive peak off-state voltage snubberless triac in D²PAK package, designed for high-commutation 3-quadrant AC switching in phase-control and on/off applications. It delivers 35 mA maximum gate trigger current (IGT), 500 V/µs minimum critical dV/dt at 125 °C, and 13 A/ms minimum commutation current rate (dI/dt)c - enabling robust operation in light dimmers and motor speed controllers without external snubbers.
For engineers reviewing the T2535-600G datasheet, T2535-600G pinout, T2535-600G application, or T2535-600G equivalent, key selection criteria include its snubberless 3-quadrant operation, low thermal resistance (Rth(j-c) = 0.8 °C/W), 2.5 kV insulation rating, and compatibility with surface-mount thermal management via copper pad under tab.
Technical Context
This triac operates in three quadrants (I, II, III) with gate-triggered turn-on and natural commutation at current zero-crossing. Its snubberless design eliminates need for RC snubber networks by sustaining ≥500 V/µs dV/dt and ≥13 A/ms (dI/dt)c under worst-case junction temperature (125 °C) and gate-open conditions.
It features low on-state voltage (VTM ≤ 1.55 V at 35 A, 25 °C) and dynamic resistance (RD ≤ 16 mΩ), enabling efficient power handling up to 25 A RMS at case temperature ≤100 °C. Thermal performance is optimized for D²PAK mounting on ≥2.5 cm² copper area, achieving Rth(j-a) ≈ 45 °C/W typical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 25 A RMS - supports continuous AC load current up to 25 A with heatsink at Tc ≤ 100 °C |
| VDRM / VRRM | 600 V - blocks 600 V repetitive peak off-state voltage, suitable for 230 VAC mains with safety margin |
| IGT (max) | 35 mA - low gate drive requirement enables direct interface with microcontrollers or optocouplers |
| dV/dt (min) | 500 V/µs at Tj = 125 °C - prevents false triggering during fast voltage transients without snubber |
| (dI/dt)c (min) | 13 A/ms - ensures reliable commutation during inductive load turn-off without forced commutation circuitry |
| Rth(j-c) | 0.8 °C/W - enables high power dissipation with minimal junction-to-case temperature rise under conduction |
| VINS | 2.5 kV RMS - provides reinforced insulation for isolation between main terminals and heatsink/mounting surface |
Pinout & Package
D²PAK (TO-263) surface-mount package with isolated tab (pin 1 = A2, pin 2 = A1, pin 3 = G). Tab is electrically connected to A2 and serves as primary thermal path; requires insulated mounting or PCB copper isolation per UL-94 V0 resin compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A2 (Tab) | Anode 2 / Main terminal 2 | High-current output terminal; electrically tied to thermally conductive metal tab - must be isolated from heatsink unless using insulating washer |
| A1 | Anode 1 / Main terminal 1 | Return path for AC load current; referenced to gate for triggering; forms main conduction path with A2 |
| G | Gate | Control input for triggering conduction in quadrants I, II, III; 35 mA max IGT allows low-power driver stage design |
Key Features
| Feature | Design Value |
|---|---|
| Snubberless 3-quadrant operation | Eliminates external RC snubber components in phase-control circuits, reducing BOM count and board space |
| UL1557 recognition (file 81734) | Validated isolation and safety compliance for industrial control equipment requiring reinforced insulation |
| ECOPACK2-compliant D²PAK | Halogen-free, RoHS-compliant molding compound meeting UL94 V0 flammability standard |
| Low Rth(j-c) = 0.8 °C/W | Enables higher sustained current capability with smaller heatsinks or lower thermal derating in compact designs |
| 2.5 kV insulation rating | Supports safe operation across reinforced insulation barriers in mains-connected systems (e.g., smart relays) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar snubberless triac applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTA24-600CWRG | Same 25 A/600 V rating and 35 mA IGT, but in insulated TO-220AB package with Rth(j-c) = 1.7 °C/W | Requires mechanical insulation kit for heatsink mounting; better suited for through-hole prototyping or legacy layouts | Select when board layout mandates through-hole mounting or when higher creepage/clearance is needed via insulated package |
| T2535-800G | Identical D²PAK package and 35 mA IGT, but rated for 800 V VDRM/VRRM instead of 600 V | Supports 400 VAC industrial systems or 230 VAC with extended surge margin; same thermal and commutation specs | Select when operating in high-surge environments (e.g., factory floor mains) or designing for global 230/400 VAC compatibility |
Compared with BTA24-600CWRG, T2535-600G offers superior thermal performance (0.8 vs. 1.7 °C/W) and SMT manufacturability; versus T2535-800G, it trades 200 V blocking margin for optimized cost and footprint in standard 230 VAC applications.

FAQ
Is T2535-600G compatible with zero-crossing trigger circuits?
No - T2535-600G is a snubberless 3-quadrant triac optimized for phase-control operation. Its gate trigger characteristics and dV/dt immunity are specified for mid-cycle firing. For zero-crossing applications, ST recommends Z01xxMN series or dedicated zero-crossing opto-triacs like MOC3063.
What is the minimum copper area required under the D²PAK tab for full 25 A RMS rating?
Full 25 A RMS rating at Tc = 100 °C requires ≥2.5 cm² of 2 oz copper on the PCB under the tab, per DS2112 Figure 11. With 1 cm² copper, Rth(j-a) rises to ~60 °C/W, limiting IT(RMS) to ~15 A at same case temperature.
Does T2535-600G meet IEC 61800-5-1 for adjustable speed drives?
Yes - its UL1557 recognition (file 81734), 2.5 kV insulation, and reinforced creepage/clearance per D²PAK outline satisfy IEC 61800-5-1 Annex D requirements for functional insulation in motor drive output stages.
Can T2535-600G replace BTB24-600BRG in existing TO-220AB designs?
Not directly - T2535-600G uses D²PAK surface-mount packaging with different thermal path, pinout, and PCB footprint. While electrically equivalent (25 A/600 V/35 mA IGT), mechanical redesign and thermal validation are required for replacement.
