STMicroelectronics TN2010H-6FP

Overview

TN2010H-6FP from STMicroelectronics is a high-temperature, insulated-packaged silicon controlled rectifier (SCR) rated for 20 A RMS conduction, 600 V peak off-state voltage, and 150 °C junction operation. It features 10 mA gate trigger current, 400 V/µs dV/dt immunity at 150 °C, and 100 A/µs critical dI/dt, enabling robust motorbike voltage regulators and solid-state relays.

For engineers reviewing the TN2010H-6FP datasheet, TN2010H-6FP pinout, TN2010H-6FP application, or TN2010H-6FP equivalent, key selection criteria include insulated TO-220FPAB thermal performance, high-temperature gate sensitivity, surge current capability (197 A), and noise-immune triggering in compact AC control circuits.

Technical Context

This SCR operates as a unidirectional, gate-triggered power switch with latching behavior after turn-on. Its insulated TO-220FPAB package enables back-to-back configuration without external isolation, supporting bidirectional AC control topologies like light dimmers and motor starters.

Designed for high-noise industrial environments, it maintains 400 V/µs dV/dt immunity up to 150 °C and delivers low on-state voltage (1.6 V max at 40 A, 25 °C) with dynamic resistance of 17.5 mΩ at 150 °C - critical for minimizing conduction losses in thermally constrained designs.

Key Specifications

Pinout & Package

Packaged in an insulated TO-220FPAB housing with creepage/clearance optimized for 2000 VRMS isolation, this device uses a 3-terminal configuration: Anode (A), Cathode (K), and Gate (G). The case is electrically isolated from all terminals.

FAQ

What is the maximum allowable case temperature for continuous 20 A RMS operation?

The datasheet specifies IT(RMS) = 20 A at Tc = 80 °C. Operation at higher case temperatures requires derating: 12.7 A at 99 °C and 8 A at 112 °C. Exceeding these limits risks thermal runaway due to increased on-state voltage and reduced dV/dt immunity.

Can TN2010H-6FP be used in back-to-back configuration without external isolation?

Yes - its TO-220FPAB package provides 2000 VRMS insulation between case and terminals, enabling direct back-to-back mounting on a common heatsink for bidirectional AC switching in dimmers and soft-start circuits without additional isolation barriers.

What gate drive circuitry is recommended for reliable triggering?

A pulse of ≥10 mA (max), ≥1.3 V, with rise time ≤100 ns and duration ≥10 µs is required. A series resistor (e.g., 100 Ω) with a 12 V source and RC snubber (100 Ω + 100 nF) at the gate suppresses ringing and ensures clean turn-on under high dV/dt conditions.

Is TN2010H-6FP compliant with modern environmental standards?

Yes - it is ECOPACK®2 certified: lead-free, halogen-free, and RoHS-compliant. The epoxy meets UL94 V0 flammability rating, and packaging adheres to JEDEC J-STD-020 moisture sensitivity level (MSL) 1 for unlimited floor life at <30 °C/85% RH.
