STMicroelectronics DMV1500HDFD6

Overview

DMV1500HDFD6 from STMicroelectronics is a dual-function high-voltage damper + modulation diode in a single insulated TO-220FPAB F6 package, designed for horizontal deflection stages in CRT TVs with E/W correction. It integrates a 1500 V damper diode (IF(AV) = 6 A, trr = 150 ns, VF = 1.0 V) and a 600 V modulation diode (IF(AV) = 3 A, trr = 60 ns, VFP = 5 V), enabling compact, thermally efficient deflection circuit design.

For engineers reviewing the DMV1500HDFD6 datasheet, DMV1500HDFD6 pinout, DMV1500HDFD6 application, or DMV1500HDFD6 equivalent, key selection criteria include verified dual-diode isolation (2000 VRMS), low conduction loss equations, turn-on switching timing (tfr ≤ 470 ns), and thermal resistance (Rth(j-c) = 3.8 °C/W) for CRT horizontal output stage reliability.

Technical Context

This device implements two functionally independent silicon planar diodes on one die: a high-breakdown 1500 V damper diode optimized for energy recovery during flyback, and a faster 600 V modulation diode with 60 ns typical reverse recovery for precise E/W correction waveform shaping. Both share common thermal management via the insulated case but operate with separate electrical paths.

Its TO-220FPAB F6 package features bent leads (FD6 variant), 2000 VRMS insulation, 7 pF inter-terminal capacitance, and UL94 V0 epoxy - all validated for sustained operation at Tj = 150 °C with junction-to-case thermal resistance of 3.8 °C/W under defined mounting torque (0.4–0.6 N·m).

FAQ

What is the maximum junction temperature and how is it enforced?

The DMV1500HDFD6 has a maximum operating junction temperature of 150 °C, validated per absolute maximum ratings in Table 2. This limit is enforced through its 3.8 °C/W junction-to-case thermal resistance and specified mounting torque (0.4–0.6 N·m), ensuring safe heat transfer to an adequately sized heatsink under 6 A average damper current and 3 A modulation current.

Can the damper and modulation sections share the same heatsink?

Yes - the TO-220FPAB F6 package features a single insulated metal tab rated for 2000 VRMS isolation between damper and modulation terminals. This allows both sections to mount to the same heatsink without electrical shorting, while maintaining functional separation and minimizing thermal resistance across the entire device.

How does the FD6 bending affect PCB layout?

The FD6 designation indicates bent leads optimized for surface-mount-like insertion into through-hole PCBs with reduced height clearance. Per Figure 16 and Table 8, lead bend radius is 1 mm typ, with L3 = 4.8 mm and L4 = 3.4–4.8 mm - enabling compact placement near horizontal output transistors while maintaining creepage distance for 2000 VRMS isolation.

Is this part compliant with RoHS and halogen-free standards?

Yes - DMV1500HDFD6 is supplied in an ECOPACK® package with lead-free second-level interconnect, compliant with JEDEC JESD97 and RoHS Directive 2011/65/EU. The UL94 V0 epoxy is halogen-free, and full compliance documentation is marked on inner box labels per ST's environmental policy.
