Product details
Overview
TN5015H-6G from STMicroelectronics is a high-temperature, 50 A, 600 V RMS silicon-controlled rectifier (SCR) in D²PAK package, rated for continuous operation up to 150 °C junction temperature, with 500 V/µs dV/dt immunity at Tj = 150 °C and 15 mA gate trigger current - used in motorbike voltage regulator circuits, solid-state relays, and industrial inrush limiting.
For engineers reviewing the TN5015H-6G datasheet, TN5015H-6G pinout, TN5015H-6G application, or TN5015H-6G equivalent, key selection criteria include peak off-state voltage (600 V), thermal resistance (0.6 °C/W j-c), turn-on dI/dt capability (100 A/µs), gate sensitivity (IGT ≤ 15 mA), and ECOPACK®2-compliant SMD packaging.
Technical Context
This SCR features a robust thyristor structure optimized for high-temperature switching in AC line-controlled applications. Its 150 °C maximum junction temperature enables operation in thermally constrained environments without derating, while its 500 V/µs dV/dt rating at full temperature ensures noise-immune triggering in noisy motor drive and crowbar protection circuits.
The device supports fast turn-on (typ. 1.9 µs gate trigger delay) and rapid current rise (100 A/µs), enabling precise phase-angle control in motor starters and compact solid-state relay designs. Its low on-state voltage (max. 1.65 V at 100 A, 25 °C) and dynamic resistance (≤9 mΩ at 150 °C) minimize conduction losses during sustained 50 A RMS operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 600 V - blocks 600 V repetitive peak off-state voltage, suitable for 400 V AC mains applications with safety margin |
| IT(RMS) | 50 A at Tc = 120 °C - delivers full-rated RMS current with heatsink interface at 120 °C case temperature |
| IGT | ≤15 mA - low gate drive requirement enables direct MCU GPIO triggering without external amplification |
| dV/dt | ≥500 V/µs at Tj = 150 °C - prevents false triggering in high-noise industrial motor control environments |
| dI/dt | 100 A/µs - supports fast, controlled turn-on for inrush limiting and phase-controlled dimming |
| Rth(j–c) | ≤0.6 °C/W - enables efficient heat transfer to heatsink, critical for high-power density SMD designs |
| Tj max | 150 °C - allows operation in under-hood or enclosed industrial enclosures without forced cooling |
Pinout & Package
The TN5015H-6G uses a 3-pin D²PAK (TO-263) surface-mount package with exposed metal tab for thermal and electrical connection. Pin 1 (Anode), Pin 2 (Cathode), Pin 3 (Gate) are arranged linearly; the metal tab is electrically connected to the Anode and serves as primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1 + Tab) | Main power input terminal | Electrically and thermally tied to heatsink; carries full load current and dissipates heat directly |
| Cathode (Pin 2) | Main power output terminal | Reference node for gate drive; connects to load return path and gate circuit common |
| Gate (Pin 3) | Control input | Low-energy trigger point requiring ≤15 mA pulse; isolated from power terminals by internal PNPN structure |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction rated to 150 °C - eliminates need for oversized heatsinks in space-constrained motorbike regulators |
| Noise-immune triggering | 500 V/µs dV/dt at 150 °C - maintains reliable turn-on in EMI-heavy alternator and starter circuits |
| Fast turn-on dynamics | 1.9 µs typical gate trigger delay - enables precise phase-angle control in 50/60 Hz AC power regulation |
| Low conduction loss | 1.65 V max VTM at 100 A - reduces power dissipation and thermal stress in 50 A RMS continuous duty |
| ECOPACK®2 compliance | Lead-free, halogen-free, UL94 V0 epoxy - meets RoHS and environmental requirements for global industrial deployment |
Applications
| Motorbike Voltage Regulator | Solid-State Relay |
|---|---|
Use Scenario: Regulating alternator output in 12 V motorcycle electrical systems under wide ambient temperature swings (-40 to +125 °C). IC Role / Device Role / Timing Role: Main AC-to-DC rectifying and phase-controlled shunt regulator switch. Use Value: 150 °C Tj rating avoids thermal shutdown during prolonged idling; 600 V VDRM accommodates alternator transients up to 400 V peak. |

IC Role / Device Role / Timing Role: Bidirectional AC power switch triggered by optocoupler-isolated gate signal. Use Value: D²PAK SMD footprint enables compact PCB layout; 500 V/µs dV/dt prevents false turn-on from contactor-induced transients. |

Use Value: 15 mA IGT allows direct microcontroller drive; low VTM minimizes heating during extended partial-conduction startup cycles. |
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 |
|---|---|---|---|
| STTH5010D | 1000 V VRRM, 50 A IT(RMS), but diode (not SCR); no gate control | Replaces only in uncontrolled rectification; cannot perform phase control or crowbar functions | Select only if gate-triggered switching is not required and higher voltage blocking is needed |
| BT139-600E | 600 V VRRM, 16 A IT(RMS), TO-220 package, IGT = 15 mA, Tj = 125 °C | Lower current rating and thermal limit restrict use to <20 A RMS loads; through-hole mounting limits board density | Acceptable for lower-power motor controls where D²PAK SMD assembly is not required |
Compared with BT139-600E, TN5015H-6G delivers 3× higher RMS current and 25 °C higher junction temperature in an SMD package, enabling compact, high-power-density designs; versus STTH5010D, it adds gate controllability essential for regulation and protection functions.

FAQ
What is the maximum allowable case temperature for continuous 50 A RMS operation?
The TN5015H-6G supports 50 A RMS continuous current only when the case temperature (Tc) is maintained at ≤120 °C, as specified in Table 2. Exceeding this requires derating per Figure 2; thermal design must ensure Rth(j–c) ≤0.6 °C/W and adequate heatsinking to avoid exceeding 150 °C junction temperature.
Can TN5015H-6G be used in back-to-back configuration for AC switching?
Yes - the D²PAK package and symmetrical VDRM/VRRM (600 V) rating enable compact back-to-back mounting for full AC waveform control. The device's 500 V/µs dV/dt at 150 °C ensures reliable commutation in both directions without false triggering during voltage reversal.
Is a snubber circuit required for reliable operation?
A snubber is recommended when switching inductive loads or in high-dV/dt environments, despite the device's 500 V/µs rating. ST's application note AN4375 specifies RC snubber values based on load L/R ratio and operating frequency to prevent commutation failure and ensure safe turn-off.
Does TN5015H-6G meet automotive qualification standards?
While not AEC-Q101 qualified, TN5015H-6G is widely deployed in motorbike voltage regulators due to its 150 °C Tj rating, -40 to +150 °C storage range, and ECOPACK®2 compliance. For automotive-critical systems, ST recommends formal qualification testing per AEC-Q101 or using the AEC-Q101-qualified TN5015H-6GTR variant.
