Product details

Overview

TN2010H-6G-TR from STMicroelectronics is a high-temperature, 20 A RMS sensitive-gate silicon-controlled rectifier (SCR) in D²PAK package, rated for 600 V peak off-state voltage, 10 mA gate trigger current, and 150 °C junction operation-designed for motorbike voltage regulators, solid-state relays, and inrush limiting circuits.

For engineers reviewing the TN2010H-6G-TR datasheet, TN2010H-6G-TR pinout, TN2010H-6G-TR application, or TN2010H-6G-TR equivalent, key selection criteria include dV/dt immunity at 150 °C (≥400 V/µs), turn-on dI/dt capability (100 A/µs), thermal resistance (R_th(j-c) ≤ 1.0 °C/W), and ECOPACK®2 compliance for industrial-grade reliability.

Technical Context

This SCR operates as a unidirectional, phase-controlled power switch with latching behavior after gate-triggered conduction. Its sensitive gate (I_GT ≤ 10 mA) enables direct drive from low-power microcontrollers or optocouplers without external amplification.

Thermal design centers on junction-to-case conduction (R_th(j-c) ≤ 1.0 °C/W) and 150 °C maximum T_j, allowing sustained 20 A RMS conduction at T_c = 132 °C. The D²PAK package supports SMD assembly and back-to-back configurations for AC control.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DRM/V_RRM	600 V - blocks line-voltage transients in 230 V AC systems with safety margin
I_T(RMS)	20 A at T_c = 132 °C - supports continuous motor-load currents without forced cooling
I_GT	10 mA max - compatible with standard optocoupler outputs (e.g., MOC302x)
dV/dt	400 V/µs at T_j = 150 °C - resists false triggering from EMI in noisy motor environments
dI/dt	100 A/µs - sustains rapid current rise during zero-crossing switching in dimmers and starters
R_th(j-c)	≤ 1.0 °C/W - enables compact heatsink design with <10 K temperature rise at full load
T_j max	150 °C - extends operational life in under-hood or enclosed industrial enclosures

Pinout & Package

The TN2010H-6G-TR uses a 3-pin D²PAK (TO-263) surface-mount package with exposed metal tab for thermal and electrical connection to drain/cathode. Pin 1 = Anode, Pin 2 = Cathode, Pin 3 = Gate. The tab is electrically connected to the cathode.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Pin 1)	Main current input terminal	Connects to AC line or DC source; carries full load current during conduction
Cathode (Pin 2 + Tab)	Main current return terminal	Tab provides low-inductance, high-current path to PCB ground plane or heatsink
Gate (Pin 3)	Trigger control input	Accepts low-energy pulse (≥10 mA, ≥1.3 V) to initiate conduction; isolated from power terminals

Key Features

Feature	Design Value
High junction temperature rating	150 °C operation enables use in sealed enclosures without derating at ambient up to 85 °C
High noise immunity	400 V/µs dV/dt at 150 °C prevents spurious turn-on in EMI-heavy motorbike regulator environments
Sensitive gate drive	10 mA I_GT allows direct interface with logic-level drivers or low-power optocouplers
Robust surge capability	197 A non-repetitive surge (8.3 ms) handles inrush events in lighting and motor start applications
ECOPACK®2 compliance	Lead-free, halogen-free, UL94 V0 epoxy ensures RoHS/REACH compliance and flame resistance

Applications

Motorbike Voltage Regulator

Inrush Current Limiter

Use Scenario: Regulates alternator output in 12 V motorcycle electrical systems under variable engine RPM and load conditions.

IC Role / Device Role / Timing Role: SCR acts as phase-controlled shunt regulator, clamping excess voltage by diverting current through field winding.

Use Value: 150 °C T_j and 400 V/µs dV/dt ensure stable regulation despite under-hood thermal cycling and ignition noise.

Use Scenario: Limits inrush current into large capacitive loads (e.g., power supplies, LED drivers) during cold start.

IC Role / Device Role / Timing Role: SCR is triggered after soft-start delay to bypass NTC thermistor or series resistor once steady state is reached.

Use Value: 100 A/µs dI/dt and 197 A surge rating safely handle capacitor charging transients without failure.

Solid-State Relay (AC Output)

Light Dimmer Circuit

Use Scenario: Replaces electromechanical relay in industrial control panels requiring silent, bounce-free, long-life AC switching.

IC Role / Device Role / Timing Role: SCR serves as main AC power switch, triggered via optocoupler for galvanic isolation and zero-crossing control.

Use Value: D²PAK package enables SMD mounting and thermal coupling to heatsink, supporting 20 A continuous switching at 60 Hz.

Use Scenario: Controls brightness of incandescent or halogen lamps in residential/commercial dimming modules.

IC Role / Device Role / Timing Role: SCR conducts during adjustable portion of AC half-cycle, delivering phase-cut power to lamp filament.

Use Value: Low 10 mA I_GT simplifies timing circuit design using RC networks and DIAC triggers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar SCR-based phase-control applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ST's TN2010-6G	Same die, but rated for T_j = 125 °C (not 150 °C); lower dV/dt (200 V/µs @ 125 °C)	Not suitable for under-hood or high-ambient industrial use where 150 °C operation is required	Select TN2010H-6G-TR when thermal margin >25 K above ambient is needed
Littelfuse S4025L	40 A RMS rating, 25 mA I_GT, TO-220 package, T_j = 125 °C	Better current headroom but requires higher gate drive and through-hole assembly	Choose for higher current capacity where SMD is not mandatory and gate drive >25 mA is available

Compared with TN2010-6G, the TN2010H-6G-TR delivers 25 °C higher junction rating and doubled dV/dt immunity-critical for automotive and high-noise environments-while S4025L trades SMD compatibility and gate sensitivity for raw current capacity and legacy packaging.

FAQ

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

The TN2010H-6G-TR supports 20 A RMS conduction at T_c = 132 °C, as specified in Table 2. Exceeding this case temperature requires derating per Figure 2; at T_c = 140 °C, maximum IT(AV) drops to 8 A. Thermal design must ensure the tab remains at or below 132 °C under worst-case ambient and airflow conditions.

Can TN2010H-6G-TR be used in back-to-back configuration for AC switching?

Yes-the D²PAK package and symmetrical blocking capability (V_DRM = V_RRM = 600 V) make it suitable for anti-parallel mounting to achieve full-wave AC control. Layout must maintain equal thermal paths and minimize stray inductance between devices; ST recommends using identical layout symmetry and shared heatsink mounting.

Is a snubber circuit required for reliable operation?

A snubber is recommended when driving inductive loads (e.g., motor windings) or operating near dV/dt limits. With 400 V/µs immunity at 150 °C, the device tolerates moderate transients, but a simple RC snubber (e.g., 100 Ω + 100 nF) improves robustness against voltage spikes caused by transformer leakage or contactor switching elsewhere in the system.

Does the "-TR" suffix indicate tape-and-reel packaging only, or does it affect electrical specs?

The "-TR" suffix denotes tape-and-reel packaging (1000 units per reel) and has no effect on electrical or thermal specifications. TN2010H-6G-TR is functionally and parametrically identical to TN2010H-6G (tube-packaged); only mechanical handling and logistics differ. Both share identical D²PAK footprint, marking ("TN2010H6"), and full production qualification.
