Product details
Overview
TN1215-600H from STMicroelectronics is a standard 12 A, 600 V repetitive peak off-state voltage (VDRM/VRRM) silicon-controlled rectifier (SCR) in IPAK package, with 15 mA maximum gate trigger current (IGT), designed for overvoltage crowbar protection and motor control circuits in power tools and kitchen appliances.
For engineers reviewing the TN1215-600H datasheet, TN1215-600H pinout, TN1215-600H application, or TN1215-600H equivalent, key selection considerations include RMS on-state current rating (12 A), thermal resistance junction-to-case (1.3 °C/W), critical dI/dt (50 A/µs), and IPAK mounting compatibility with FR4 PCB layouts.
Technical Context
This SCR operates as a unidirectional, gate-triggered thyristor requiring latching current (IL ≤ 80 mA) and holding current (IH ≤ 40 mA) to sustain conduction after triggering. It features a threshold voltage (Vto) of ≤ 0.85 V and dynamic resistance (Rd) ≤ 30 mΩ at Tj = 125 °C, enabling low conduction loss in high-current switching.
Its 600 V VDRM/VRRM rating supports operation in 230 V AC mains-fed systems with margin, while the 115 A non-repetitive surge rating (tp = 8.3 ms) accommodates inrush and fault transients. The device is rated for junction temperatures from –40 °C to +125 °C and uses halogen-free, lead-free ECOPACK® packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 12 A - Sustained RMS load current capability at Tc = 110 °C, defining continuous power-handling capacity |
| VDRM / VRRM | 600 V - Maximum repetitive blocking voltage in both forward and reverse directions, ensuring safe operation across 230 V AC peaks with safety margin |
| IGT (max) | 15 mA - Maximum gate current required to reliably trigger conduction, setting driver circuit current budget |
| dI/dt (critical) | 50 A/µs - Minimum rate of rise of on-state current that avoids false turn-on, guiding snubber design |
| Rth(j-c) | 1.3 °C/W - Junction-to-case thermal resistance, determining heatsink requirement for 12 A RMS operation |
| VTM (max) | 1.6 V @ 24 A - Peak on-state voltage drop under pulsed test, directly impacting conduction loss and thermal dissipation |
| I2t (fusing) | 60 A²s - Thermal energy tolerance before fuse failure, used for coordination with fast-acting fuses in crowbar circuits |
Pinout & Package
The TN1215-600H is housed in an IPAK (TO-251AA) surface-mount package with three terminals: anode (A), cathode (K), and gate (G). The package features a single exposed metal tab (anode-connected) for thermal and electrical connection, compatible with standard FR4 PCB layouts per Figure 13 and Table 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Main current entry terminal | Connected to high-side AC line or DC bus; electrically and thermally tied to exposed tab for heatsinking |
| Cathode (K) | Main current exit terminal | Reference node for gate drive; carries full load current back to return path |
| Gate (G) | Control input | Low-energy trigger point requiring ≤15 mA pulse; sensitive to dv/dt-induced false turn-on without proper RC snubbing |
Key Features
| Feature | Design Value |
|---|---|
| Optimized for crowbar and phase-control topologies | Guaranteed latching (IL ≤ 80 mA) and holding (IH ≤ 40 mA) currents enable reliable turn-on/hold in low-power gate drive designs |
| High surge robustness | 115 A non-repetitive surge (8.3 ms) supports inrush limiting and short-circuit protection without latch-up |
| Low conduction loss | On-state voltage ≤1.6 V at 24 A and dynamic resistance ≤30 mΩ reduce power dissipation and thermal stress |
| ECOPACK® environmental compliance | Halogen-free molding resin, lead-free terminations, and UL94 V0 epoxy meet RoHS and WEEE requirements |
Applications
| Overvoltage Crowbar Protection | Power Tool Motor Control |
|---|---|
Use Scenario: Fast-acting shutdown circuit triggered by overvoltage detection to short main supply and blow fuse. IC Role / Device Role / Timing Role: SCR acts as high-current switch activated by comparator-driven gate pulse; conduction must initiate within microseconds of fault detection. Use Value: 600 V VDRM ensures safe blocking during normal 230 V AC operation; 115 A surge rating handles transient energy until fuse clears. | Use Scenario: Phase-angle controlled speed regulation in universal motor-based corded drills and sanders. IC Role / Device Role / Timing Role: SCR serves as line-synchronized AC switch; precise gate timing determines conduction angle and average motor power. Use Value: 12 A IT(RMS) supports continuous motor loads up to ~1.8 kW; 50 A/µs dI/dt rating prevents commutation failure during zero-crossing transitions. |
| Inrush Current Limiting | Voltage Regulation Circuits |
Use Scenario: Soft-start for transformer-coupled or capacitive-input power supplies to prevent fuse nuisance blowing. IC Role / Device Role / Timing Role: SCR is gated after initial delay to bypass NTC thermistor or series resistor once bulk capacitor charges. Use Value: 15 mA IGT enables direct drive from microcontroller GPIO via small buffer; IPAK package allows compact layout near input stage. | Use Scenario: Adjustable AC output regulation using feedback-controlled firing angle in lab-grade bench supplies. IC Role / Device Role / Timing Role: SCR functions as precision-controlled bidirectional switch in back-to-back or single-phase regulator topology. Use Value: Low Vto (≤0.85 V) and Rd (≤30 mΩ) minimize regulation error and improve line/load regulation stability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TYN612RG | Same 600 V VDRM, 12 A IT(RMS), but TO-220AB through-hole package; 15 mA IGT; Rth(j-c) = 1.3 °C/W | Requires through-hole assembly and larger board area; better natural convection cooling without heatsink | Select when manual assembly, higher thermal mass, or legacy footprint compatibility is required |
| TN1215-600G | Same electrical specs, but D2PAK package; Rth(j-c) = 1.3 °C/W; weight = 1.5 g vs. 0.3 g for IPAK | Higher thermal inertia and larger pad area; suited for higher ambient or sustained 12 A operation | Select when PCB copper area is available and junction temperature margin is prioritized over size |
Compared with TYN612RG and TN1215-600G, the TN1215-600H offers identical electrical performance in a smaller, lighter IPAK footprint optimized for automated SMT lines-ideal where board space and assembly efficiency are constrained, though thermal interface design must ensure tab contact integrity.

FAQ
What is the maximum junction temperature for continuous operation?
The TN1215-600H has an operating junction temperature range of –40 °C to +125 °C. For continuous 12 A RMS operation, case temperature must be maintained at ≤110 °C per Table 2, requiring thermal design that limits junction rise to ≤15 °C above case using Rth(j-c) = 1.3 °C/W.
Can TN1215-600H be driven directly from a microcontroller GPIO?
No-direct GPIO drive is unsafe. With IGT(max) = 15 mA and VGT(max) = 1.3 V, a microcontroller GPIO (typically 3.3 V/20 mA) may trigger the SCR but risks false turn-on due to dv/dt sensitivity. A dedicated gate driver with RC snubber and current-limiting resistor is required for reliable, noise-immune operation.
Is the IPAK package lead-free and RoHS compliant?
Yes. The TN1215-600H uses ST's ECOPACK® packaging, which specifies halogen-free molding compound, lead-free terminations, and UL94 V0-rated epoxy-fully compliant with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1 (unlimited floor life at ≤30 °C/85% RH).
How does the 60 A²s I²t rating impact fuse selection?
The 60 A²s fusing I²t value defines the maximum let-through energy the SCR can withstand before thermal failure. Fuse selection must ensure its I²t rating is ≤60 A²s at the prospective short-circuit current-e.g., a 10 A fast-blow fuse with 45 A²s I²t provides coordination margin for crowbar operation without SCR destruction.
