Product details
Overview
TN2015H-6FP from STMicroelectronics is a high-temperature, insulated 20 A rms silicon controlled rectifier (SCR) in TO-220FPAB package, rated for 600 V repetitive peak off-state voltage (VDRM/VRRM), 15 mA gate triggering current (IGT), and 750 V/µs dV/dt immunity at 150 °C junction temperature-designed for motorbike voltage regulators and solid-state relays.
For engineers reviewing the TN2015H-6FP datasheet, TN2015H-6FP pinout, TN2015H-6FP application, or TN2015H-6FP equivalent, key selection criteria include insulated package voltage rating (2000 VRMS), thermal resistance (Rth(j-c) = 4.0 °C/W), dI/dt capability (100 A/µs), and UL certification (File E81734).
Technical Context
This SCR operates with a latching current (IL) ≤ 60 mA and holding current (IH) ≤ 50 mA at 25 °C, enabling reliable turn-on and sustained conduction in phase-controlled AC circuits. Its gate sensitivity (IGT ≤ 15 mA at 12 V) and high dV/dt immunity (≥750 V/μs up to 150 °C) support robust triggering in noisy industrial environments.
The device features low on-state voltage (VTM ≤ 1.6 V at 40 A, 25 °C) and dynamic resistance (Rd ≤ 17.5 mΩ at 150 °C), minimizing conduction losses in high-current motor control and inrush limiting applications. Its insulated TO-220FPAB package enables back-to-back configuration without external isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 600 V - supports 230 VAC mains with ≥2.6× safety margin against transient overvoltage |
| IT(RMS) | 20 A at Tc = 80 °C - delivers full-rated current with standard heatsink mounting |
| dV/dt | 750 V/µs at Tj = 150 °C - prevents false triggering in high-noise motor drive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR-based AC power control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BT139-600E | Non-insulated TO-220 package; Rth(j-c) = 3.5 °C/W; IGT = 10 mA max; VDRM = 600 V | Requires external insulation for back-to-back use; higher thermal efficiency but no built-in 2000 VRMS barrier | Select when board-level isolation is already implemented and lower gate drive current is prioritized. |
| TYN612 | TO-220AB (non-insulated); IT(RMS) = 12 A; VDRM = 600 V; IGT = 50 mA max; dV/dt = 200 V/µs | Lower current rating and noise immunity; not rated for 150 °C operation; UL not specified | Choose only for cost-sensitive, low-noise, low-temperature ambient applications where 20 A and 150 °C are not required. |
Compared with BT139-600E and TYN612, the TN2015H-6FP uniquely combines 20 A RMS current, 150 °C junction rating, 750 V/µs dV/dt, and 2000 VRMS insulation in one package-making it the only drop-in solution for thermally demanding, safety-certified, back-to-back AC control designs.

FAQ
What is the maximum allowable case temperature for continuous 20 A RMS operation?
The TN2015H-6FP supports 20 A RMS continuous conduction at Tc = 80 °C, as specified in Table 2. Operation above this requires derating per Figure 2; at Tc = 99 °C, IT(RMS) drops to 10 A. Thermal design must ensure junction temperature remains ≤150 °C using Rth(j-c) = 4.0 °C/W and appropriate heatsinking.
Can TN2015H-6FP be used in back-to-back configuration without additional isolation?
Yes-the TO-220FPAB package provides 2000 VRMS insulation between terminals and mounting tab, enabling direct back-to-back mounting on a common heatsink. This eliminates external isolation components and simplifies PCB layout for bidirectional AC switching in dimmers and SSRs.
Is a snubber circuit required for reliable operation?
A snubber is recommended when switching inductive loads or in high-dV/dt environments, even though the device has 750 V/µs immunity at 150 °C. The datasheet does not waive snubber use for all conditions; typical design uses RC snubber across A–K to suppress voltage transients exceeding VDRM during commutation.
Does TN2015H-6FP meet RoHS and REACH requirements?
Yes-TN2015H-6FP is ECOPACK®2 compliant, meaning it meets RoHS Directive 2011/65/EU, is lead-free, and uses halogen-free molding compound. Full compliance documentation, including material declarations and test reports, is available via ST's official product page and ECOPACK® portal.
