STMicroelectronics DMV1500HFD5

Overview

DMV1500HFD5 from STMicroelectronics is a dual-function insulated high-voltage damper and modulation diode in a single TO-220FPAB-F5 package, designed for horizontal deflection stages in CRT video displays with E/W correction. It integrates a 1500 V damper diode (IF(AV) = 6 A, trr ≤ 125 ns, VF ≤ 1.7 V) and a 600 V modulation diode (IF(AV) = 3 A, trr ≤ 50 ns, VF ≤ 1.4 V), enabling compact, thermally stable EHT circuitry in analog TV and monitor designs.

For engineers reviewing the DMV1500HFD5 datasheet, DMV1500HFD5 pinout, DMV1500HFD5 application, or DMV1500HFD5 equivalent, key selection criteria include verified dual-diode isolation (2000 VRMS), fast recovery performance under high dIF/dt (−50 A/µs), low conduction loss modeling (P = 1.35×IF(AV) + 0.59×IF²RMS for damper), and F5-bent lead configuration for automated through-hole assembly.

Technical Context

This device implements two planar-junction diodes on a shared die within an insulated TO-220FPAB-F5 housing: one optimized for high-voltage energy recycling in flyback damper circuits (1500 V VRRM, 80 A IFSM), the other for precise video signal modulation (600 V VRRM, 35 A IFSM). Both share thermal coupling to the case (Rth(j–c) = 3.6 °C/W) but operate with distinct switching profiles-damper exhibits tfr ≤ 350 ns and VFP ≤ 25 V at 6 A, while modulation achieves tfr ≤ 240 ns and VFP ≤ 8 V at 3 A.

Its design targets CRT horizontal deflection systems requiring simultaneous high breakdown, fast turn-off, low forward drop, and galvanic isolation between primary-side switching and secondary-side modulation paths. The 7 pF junction capacitance (at VR = 30 V) and controlled reverse recovery charge (Qrr typ. 100–200 nC depending on dIF/dt) support stable timing and minimal ringing in resonant line scan circuits.

FAQ

What is the maximum junction temperature rating for DMV1500HFD5?

The absolute maximum operating junction temperature is 150 °C, validated per Table 3 in the official datasheet. This rating applies to both damper and modulation diodes under continuous conduction. Derating is required above 125 °C ambient when mounted on a heatsink with Rth(j–c) = 3.6 °C/W and Rth(c–a) ≤ 15 °C/W.

Can DMV1500HFD5 be used in non-CRT applications such as switch-mode power supplies?

No-DMV1500HFD5 is characterized and qualified exclusively for CRT horizontal deflection use cases. Its recovery behavior, surge ratings, and thermal profile are optimized for 15.625 kHz flyback waveforms, not generic SMPS topologies. Using it in non-CRT applications voids ST's reliability guarantees and may result in premature failure due to unvalidated dIF/dt stress or reverse recovery charge mismatch.

How does the F5 lead bending affect PCB layout and thermal performance?

The F5 bend positions pins at 15° outward from vertical, enabling secure through-hole retention in high-vibration environments and simplifying wave soldering. Thermal resistance remains unchanged (Rth(j–c) = 3.6 °C/W) because the metal tab contact area and interface pressure are preserved; however, bent leads reduce mechanical stress on solder joints during thermal cycling.

Is the common cathode (Pin 2) internally connected to the metal tab?

Yes-Pin 2 (common cathode) is electrically bonded to the isolated metal tab. The 2000 VRMS insulation rating applies between this cathode/tab structure and both anode terminals (Pin 1 and Pin 3). No external connection to the tab is required for circuit functionality, but it must be thermally attached to a heatsink for rated power dissipation.
