Product details
Overview
DMV1500HFD from STMicroelectronics is a dual-function insulated high-voltage damper and modulation diode in a single TO-220FPAB 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 deflection circuitry.
For engineers reviewing the DMV1500HFD datasheet, DMV1500HFD pinout, DMV1500HFD application, or DMV1500HFD equivalent, key selection criteria include verified dual-diode isolation (2000 VRMS), junction-to-case thermal resistance of 3.6 °C/W, specified turn-on switching behavior (tfr ≤ 350 ns damper / 240 ns modulator), and low conduction loss equations per diode function.
Technical Context
The DMV1500HFD implements two planar-junction diodes on a shared die within an insulated TO-220FPAB housing: one optimized for high-voltage energy recovery (damper) and the other for fast signal modulation (modulator). Its design targets CRT horizontal output stage requirements-specifically handling triangular flyback waveforms with peak currents up to 80 A (damper) and 35 A (modulator), while maintaining tight thermal dispersion under automated assembly.
Electrical separation between diodes is ensured by 2000 VRMS insulation and 7 pF inter-terminal capacitance. Recovery performance is characterized at dIF/dt = −50 A/µs (damper) and dIF/dt = 80 A/µs (modulator), with distinct trr, Qrr, and Irm dependencies confirmed across Tj = 25°C to 125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM (Damper) | 1500 V - Withstands repetitive reverse voltage in CRT flyback transformer primary clamp applications |
| VRRM (Modulator) | 600 V - Supports E/W correction voltage swing without breakdown during horizontal retrace |
| trr (Damper) | ≤125 ns - Enables efficient energy transfer with minimal switching loss at ~15.7 kHz horizontal frequency |
| trr (Modulator) | ≤50 ns - Ensures clean, low-distortion modulation edge timing for dynamic geometry correction |
| IF(AV) (Damper) | 6 A - Sustains average current under continuous horizontal deflection duty cycle (δ ≈ 0.45) |
| IF(AV) (Modulator) | 3 A - Handles average current for real-time horizontal width and linearity control signals |
| Rth(j-c) | 3.6 °C/W - Allows direct heatsink mounting for thermal management in space-constrained CRT chassis |
| Isolation Voltage | 2000 VRMS - Provides reinforced insulation between damper and modulation terminals for safety compliance |
Pinout & Package
DMV1500HFD uses the insulated TO-220FPAB package (F5 bending option available), featuring three terminals: Pin 1 (Anode Damper), Pin 2 (Cathode Common), Pin 3 (Anode Modulator). The metal tab is electrically isolated and serves as mechanical heatsink interface only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Damper Diode | Connects to flyback transformer primary winding node; carries high dv/dt flyback pulse |
| Pin 2 | Common Cathode | Shared cathode node tied to ground reference; enables compact dual-diode topology |
| Pin 3 | Anode of Modulation Diode | Accepts E/W correction waveform; operates at lower voltage but higher dIF/dt than damper |
Key Features
| Feature | Design Value |
|---|---|
| Dual-diode integration | Single-package solution eliminates interconnect inductance and layout mismatch between damper and modulator paths |
| Insulated construction | 2000 VRMS isolation enables safe common-cathode configuration without external barrier components |
| Fast turn-on switching | tfr ≤ 350 ns (damper) and ≤ 240 ns (modulator) ensures precise timing alignment in deflection waveform synthesis |
| Low forward voltage | VF ≤ 1.7 V (damper @ 6 A) and ≤ 1.4 V (modulator @ 3 A) reduces conduction loss and thermal stress |
| Planar junction technology | Delivers consistent trr, Qrr, and IR across production lots-critical for CRT display uniformity and longevity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-diode damper/modulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH12R06D | Single 600 V, 12 A ultrafast diode; no integrated damper function or insulation | Requires external damper diode and isolation barrier; increases PCB area and parasitic inductance | Only suitable when modulation-only function is needed and damper is implemented separately |
| STTH8R06D | Single 600 V, 8 A ultrafast diode; lacks 1500 V damper rating and common-cathode dual topology | Cannot replace DMV1500HFD in CRT horizontal output stage without redesigning clamp and modulation paths | Applicable only in non-CRT applications such as SMPS secondary rectification where dual function is unnecessary |
Compared with STTH12R06D and STTH8R06D, DMV1500HFD uniquely delivers co-packaged, insulated 1500 V/600 V dual functionality with validated timing alignment-enabling drop-in replacement in legacy CRT designs without layout or thermal derating changes.

FAQ
What is the purpose of the insulated TO-220FPAB package in DMV1500HFD?
The insulated TO-220FPAB package provides 2000 VRMS electrical isolation between the damper and modulation diode terminals, allowing safe common-cathode connection without external insulation barriers. This meets safety standards for CRT deflection circuits and prevents signal coupling that could distort E/W correction waveforms.
How does DMV1500HFD handle thermal management in high-power CRT applications?
With a junction-to-case thermal resistance of 3.6 °C/W and a metal tab designed for direct heatsink mounting, DMV1500HFD dissipates up to 12 W (damper) and 4.5 W (modulator) under typical operating conditions. Its planar construction ensures uniform thermal distribution, minimizing hot spots during sustained horizontal retrace pulses.
Can DMV1500HFD be used in non-CRT applications such as switch-mode power supplies?
No-DMV1500HFD is optimized for CRT horizontal deflection timing, with recovery characteristics (trr, tfr), voltage ratings (1500 V/600 V), and conduction loss equations tailored to triangular flyback waveforms. Its dual-anode/common-cathode topology and insulation scheme do not align with SMPS rectifier requirements.
What is the significance of the F5 bending option in DMV1500HFD5?
The F5 bending option (DMV1500HFD5) modifies lead geometry to accommodate specific PCB footprint constraints in compact CRT chassis designs. It retains identical electrical specs and thermal performance but features bent leads for improved mechanical retention and reduced board stress during thermal cycling.
