Product details
Overview
TN1515-600B from STMicroelectronics is a 15 A, 600 V RMS-rated silicon-controlled rectifier (SCR) in DPAK surface-mount package, designed for high-density AC power control. It delivers 165 A non-repetitive surge current (tp = 8.3 ms), features 15 mA gate trigger current (IGT), and operates with 200 V/µs dV/dt immunity at 125 °C - enabling use in universal motor phase control and crowbar protection circuits.
For engineers reviewing the TN1515-600B datasheet, TN1515-600B pinout, TN1515-600B application, or TN1515-600B equivalent, key selection criteria include verified IT(RMS) = 15 A, VDRM/VRRM = 600 V, IGT = 15 mA, thermal resistance Rth(j-c) = 1.2 °C/W, and DPAK mechanical compatibility with FR4 PCB layouts using 0.5 cm² copper area.
Technical Context
The TN1515-600B is a four-layer p-n-p-n thyristor with gate-controlled turn-on and natural commutation. Its latching current (IL ≤ 60 mA) and holding current (IH ≤ 40 mA) ensure reliable conduction initiation and maintenance under varying load conditions. The device sustains 150 A repetitive surge (tp = 10 ms) and exhibits 25 mΩ dynamic on-state resistance (RD) at 125 °C.
Thermal design relies on junction-to-case conduction (Rth(j-c) = 1.2 °C/W) and is validated for Tc = 109 °C operation. Gate drive requires ≥2 mA minimum IGT and tolerates up to 5 V reverse gate voltage (VRGM), supporting robust triggering in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 15 A - supports continuous AC load current up to 15 A at 180° conduction angle with case temperature ≤109 °C |
| VDRM / VRRM | 600 V - blocks 600 V peak off-state voltage in both forward and reverse directions |
| IGT | 15 mA max - gate trigger current sufficient for standard 12 V/33 Ω driver circuits |
| dV/dt | 200 V/µs min - prevents false turn-on during rapid voltage transients at 125 °C junction temperature |
| Rth(j-c) | 1.2 °C/W - enables direct heatsinking via DPAK tab; 15 A operation requires ≤18 °C temperature rise across case interface |
| ITSM (tp = 8.3 ms) | 165 A - withstands single-cycle AC line surges without failure |
| VTM | 1.6 V max at 30 A - limits conduction loss to ≤48 W instantaneous power dissipation |
Pinout & Package
The TN1515-600B uses a 3-terminal DPAK (TO-252) surface-mount package with exposed metal tab serving as the cathode connection. Package dimensions comply with ST's mechanical drawing: D = 6.22 mm, E = 6.73 mm, L = 1.78 mm, and tab thickness A2 = 0.23 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Main current entry terminal | Connected to AC line or high-side load; must withstand full VDRM and ITSM stress |
| Cathode (K) | Main current exit terminal & thermal path | Exposed metal tab - electrically and thermally tied to PCB copper pour (SCU = 0.5 cm² recommended) |
| Gate (G) | Control input for turn-on | Low-energy trigger point; requires ≥2 mA IGT and ≤1.3 V VGT; sensitive to noise above VRGM = 5 V |
Key Features
| Feature | Design Value |
|---|---|
| High surge current density | 165 A non-repetitive peak (tp = 8.3 ms) enables robust overvoltage protection without external fusing |
| DPAK surface-mount footprint | Compact 6.22 × 6.73 mm outline allows high-power density layout on automated SMT lines |
| 125 °C dV/dt immunity | 200 V/µs minimum ensures stable operation in high-noise motor drive and regulator environments |
| Lead-free & halogen-free | ECOPACK®-compliant construction meets RoHS and JEDEC J-STD-020 reflow requirements |

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 |
|---|---|---|---|
| ST's TN1215-600B | 12 A IT(RMS), same VDRM/VRRM and DPAK package | Lower RMS current rating reduces thermal margin in sustained 15 A loads | Select when average load current remains ≤12 A and board space constraints match DPAK |
| ON Semiconductor's MCR12L6 | 12 A IT(RMS), TO-220 package, higher IGT (50 mA) | Through-hole mounting and higher gate drive requirement increase system cost and layout complexity | Choose only if legacy TO-220 footprint or higher surge tolerance (200 A) is prioritized over SMT efficiency |
Compared with TN1215-600B and MCR12L6, the TN1515-600B uniquely combines 15 A RMS rating, DPAK SMT compatibility, and 15 mA IGT in a single device - making it optimal for new designs requiring high-current density and automated assembly.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The TN1515-600B has an operating junction temperature range of –40 °C to +125 °C. For continuous 15 A RMS conduction, case temperature must be maintained at or below 109 °C per absolute ratings table - requiring thermal design with Rth(j-c) = 1.2 °C/W and adequate PCB copper area (0.5 cm² minimum).
Can the TN1515-600B be used in DC circuits?
No - the TN1515-600B is a half-wave controlled rectifier requiring natural current zero-crossing to commutate. It cannot sustain conduction in pure DC; forced commutation or additional circuitry would be required, which is outside its specified operation and not supported by ST's characterization.
Is the DPAK tab electrically isolated from the cathode?
No - the exposed metal tab of the DPAK package is internally connected to the cathode (K) terminal. This provides both electrical continuity and low-thermal-resistance heat transfer to the PCB copper pour, but requires appropriate isolation planning in high-voltage layouts.
What gate drive circuit is recommended for reliable triggering?
ST specifies a 12 V source with 33 Ω series resistor (delivering ~15 mA IGT) at 25 °C. At elevated temperatures, IGT may rise to 15 mA max; therefore, gate drivers should guarantee ≥15 mA into ≤1.3 V VGT while limiting peak gate current to 4 A (per IGM rating) and avoiding reverse gate voltage exceeding 5 V (VRGM).
