STMicroelectronics STTD6050H-12M2Y

Overview

STTD6050H-12M2Y from STMicroelectronics is a top-cooled ACEPACK SMIT surface-mount module integrating a single-phase half-controlled bridge rectifier with two 1200 V SCRs (TN6050HP-12) and two 1200 V diodes (STBR6012). It delivers 75 A_AV full-wave DC output current, supports 150 °C junction temperature, and provides 1000 V/µs static dV/dt immunity - enabling robust inrush current limiting in on-board chargers and motor drive AC-DC converters.

For engineers reviewing the STTD6050H-12M2Y datasheet, STTD6050H-12M2Y pinout, STTD6050H-12M2Y application, or STTD6050H-12M2Y equivalent, this device serves as a high-reliability, AEC-Q101-qualified solution for solid-state AC line rectification with integrated SCR/diode pairing, thermal robustness, and UL-recognized 4 kV insulated tab-to-lead isolation.

Technical Context

This module implements a half-controlled bridge topology where two SCRs control conduction angle while two diodes provide freewheeling paths - enabling phase-angle soft-start and bypass-based inrush current limitation. Its dual-die integration (SCR + diode per leg) allows independent gate triggering (G1/G2) and shared D+/D− outputs, supporting both mixed-control and bypass topologies per AN4606.

The ACEPACK SMIT package features isolated top-cooled metal tab (4000 V insulation), terminal pins opposite the cooling side, and optimized thermal resistance (R_th(j-c) = 0.75 °C/W per die), enabling fully automatic PCB-to-heat sink assembly without mechanical fasteners while meeting IEC 60664-1 creepage requirements (6.6 mm pin-to-pin).

Key Specifications

FAQ

What is the maximum continuous output current rating for STTD6050H-12M2Y?

The device is rated for 75 A_AV average full-wave DC output current under specified thermal conditions (T_c ≤ 106 °C). This corresponds to 85 A_RMS AC input current capability, validated per DS13702 Table 1 and Figure 6. Derating applies above 106 °C case temperature.

How is thermal management implemented given the top-cooled package?

Heat is extracted exclusively through the isolated metal tab on the top surface, requiring direct mechanical contact with a heatsink using 50 N clamping force per AN5384. No bottom-side thermal interface is needed; PCB traces serve only for electrical connection, not heat conduction.

Can STTD6050H-12M2Y replace four discrete TO-247 thyristors/diodes?

Yes - it integrates two 60 A_RMS SCRs and two 60 A_RMS diodes into a single 25 × 32.7 mm ACEPACK SMIT module, reducing footprint by >40% versus four TO-247 devices. Pinout and gate drive requirements differ, so layout and driver circuitry must be redesigned accordingly.

What standards does the insulation rating satisfy?

The 4 kV RMS tab-to-leads insulation (UL File E81734) and 6.6 mm pin-to-pin creepage meet IEC 60664-1 requirements for 600 VAC, material group II, pollution degree 2. It also satisfies AQG324 for automotive module-level qualification including thermal cycling and humidity testing.
