Product details
Overview
DMV1500SDFD from STMicroelectronics is a dual-function high-voltage damper + modulation diode in a single insulated TO-220FPAB 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 = 1.1 V) and a 600 V modulation diode (IF(AV) = 6 A, trr = 60 ns, VF = 1.0 V), enabling compact, thermally stable deflection circuit design.
For engineers reviewing the DMV1500SDFD datasheet, DMV1500SDFD pinout, DMV1500SDFD application, or DMV1500SDFD equivalent, key selection criteria include insulated voltage rating (2000 VRMS), low peak forward voltage (VFP = 26 V damper / 5 V modulation), specified turn-on switching (tfr = 350 ns / 85 ns), thermal resistance (Rth(j-c) = 4.0 °C/W), and dual-diode integration in one planar device.
Technical Context
This device implements two functionally distinct high-voltage diodes on a single die: a 1500 V damper diode optimized for energy recovery in flyback transformer circuits, and a 600 V modulation diode engineered for fast E/W correction signal injection. Both share common thermal management via the insulated TO-220FPAB case but operate with independent electrical characteristics.
The damper diode features high VRRM (1500 V), low static VF (1.1 V typ. at 6 A), and controlled reverse recovery (trr = 150 ns typ.), while the modulation diode delivers ultrafast trr (60 ns typ.), minimal VFP (5 V typ. at 6 A), and precise tfr (85 ns typ.)-enabling accurate timing control in high-frequency deflection waveforms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM (Damper) | 1500 V - Withstands peak reverse voltage in horizontal output stage without breakdown |
| VRRM (Modulation) | 600 V - Supports E/W correction voltage swing without conduction loss or failure |
| trr (Damper) | 150 ns typ. - Limits switching losses and EMI during flyback energy transfer |
| trr (Modulation) | 60 ns typ. - Enables clean, jitter-free modulation edge transitions at 56 kHz |
| VFP (Damper) | 26 V typ. - Controls peak forward overshoot during rapid current rise (dIF/dt = 80 A/µs) |
| Rth(j-c) | 4.0 °C/W - Allows direct heatsink mounting for stable junction temperature ≤150 °C under 6 A AV load |
| Insulation | 2000 VRMS - Provides reinforced isolation between diode cathodes and heatsink-mounting tab |
Pinout & Package
DMV1500SDFD uses an insulated TO-220FPAB package with three pins per diode section (damper: pins 1–3; modulation: pins 1–3), sharing a common isolated metal tab for heatsink mounting. The package meets UL94 V0 flammability rating and supports torque of 0.4–0.6 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Damper Pin 1 | Anode | Connects to horizontal output transistor collector for flyback energy path |
| Damper Pin 2 | Cathode | Routes recovered energy to B+ supply; electrically isolated from heatsink |
| Damper Pin 3 | Case / Tab | Insulated heatsink interface (2000 VRMS isolation); no internal electrical connection |
| Modulation Pin 1 | Anode | Connected to E/W correction waveform source (typically transformer secondary) |
| Modulation Pin 2 | Cathode | Feeds modulated signal into deflection yoke; isolated from damper cathode |
| Modulation Pin 3 | Case / Tab | Shared insulated tab; enables dual-diode thermal coupling without electrical coupling |
Key Features
| Feature | Design Value |
|---|---|
| Dual-diode integration | Single TO-220FPAB package contains fully independent 1500 V damper and 600 V modulation diodes, reducing PCB area and interconnect inductance |
| Insulated construction | 2000 VRMS isolation between both diode cathodes and heatsink tab eliminates need for insulating washers or pads |
| Controlled turn-on dynamics | tfr = 350 ns (damper) and 85 ns (modulation) ensure predictable forward recovery under 80 A/µs dIF/dt, critical for CRT linearity |
| Low conduction loss | VF = 1.1 V (damper) and 1.0 V (modulation) at 6 A reduces average power dissipation and improves thermal margin |
| Planar process reliability | High-yield planar technology ensures tight parameter dispersion (<±10%) across production lots for consistent deflection performance |
Applications
| Standard CRT TV Deflection | High-Resolution CRT Monitor |
|---|---|
Use Scenario: Horizontal deflection circuit in 50/60 Hz broadcast TV receivers with analog E/W correction. IC Role / Device Role / Timing Role: Damper diode recovers flyback energy; modulation diode injects parabolic E/W correction waveform synchronized to line scan. Use Value: Dual integration eliminates discrete diode layout mismatch, ensuring stable geometry correction and reduced horizontal linearity distortion. | Use Scenario: High-bandwidth CRT monitors operating at 85–100 kHz horizontal scan rates. IC Role / Device Role / Timing Role: Modulation diode provides fast, low-VFP switching for precise E/W amplitude control; damper handles higher peak currents (12 A) during extended flyback. Use Value: 60 ns trr and 5 V VFP minimize timing skew and overshoot, preserving image geometry at high resolution (1600×1200). |
| Professional Video Display | Legacy Broadcast Equipment |
Use Scenario: Studio-grade CRT-based waveform monitors and vector scopes requiring stable raster geometry. IC Role / Device Role / Timing Role: Damper maintains consistent flyback timing across temperature; modulation diode enables calibrated E/W gain adjustment. Use Value: Tight thermal resistance (4.0 °C/W) and low VF drift (≤10% from 25°C to 125°C) ensure long-term calibration stability. | Use Scenario: Analog broadcast transmitters and test equipment using CRT-based status displays. IC Role / Device Role / Timing Role: Dual diode operates in high-reliability, long-lifetime systems where replacement is costly or impractical. Use Value: Insulated TO-220FPAB construction prevents ground-loop interference and supports >15-year field operation under continuous duty. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage damper + modulation diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602CG | Single 200 V Schottky rectifier; no modulation diode, no insulation, no VFP specification | Only suitable for low-voltage auxiliary supplies-not horizontal deflection | Select only if replacing non-critical low-side rectifiers, not CRT deflection functions |
| BYV26E | 600 V ultrafast diode; single device, no damper rating, no insulation, no tfr spec | Lacks 1500 V damper capability and integrated modulation path | Acceptable only as standalone modulation diode replacement-requires separate damper |
Compared with DMV1500SDFD, STTH1602CG lacks high-voltage capability and dual functionality, while BYV26E omits insulation, damper integration, and turn-on timing control-making neither a functional substitute for CRT horizontal deflection.

FAQ
Is DMV1500SDFD still in active production?
No-DMV1500SDFD is marked as obsolete by STMicroelectronics per official documentation. However, Aetrix Electronics maintains legacy inventory and offers traceable, tested stock for repair and maintenance of existing CRT-based systems, with full compliance to original specifications and ECOPACK® environmental standards.
Can DMV1500SDFD be used in non-CRT applications?
It is not recommended. The device's 1500 V/600 V dual rating, tfr and trr optimization, and E/W correction timing behavior are specifically tuned for CRT horizontal deflection waveforms at ~15.7 kHz (TV) or ~31 kHz (monitors). Use in switch-mode power supplies or motor drives risks premature failure due to uncharacterized dV/dt stress and lack of relevant safety certifications.
What is the meaning of "FD" in DMV1500SDFD?
"FD" denotes the TO-220FPAB package variant with standard leadframe bending (as opposed to "FD6", which specifies a modified FD6 footprint per Table 8). This affects PCB pad layout and mechanical mounting-FD uses L3 = 28.6–30.6 mm and L4 = 9.8–10.6 mm, while FD6 shortens L3 to 4.8 mm and L4 to 3.4–4.8 mm for compact designs.
How does the 2000 VRMS insulation impact heatsink mounting?
The 2000 VRMS isolation allows direct mechanical attachment to a grounded heatsink without electrical isolation hardware (e.g., mica washers or silicone pads). This simplifies thermal design, improves heat transfer efficiency, and eliminates risk of insulation breakdown under transient overvoltage-critical in high-energy CRT deflection circuits where cathode-to-heatsink potential differences exceed 1 kV.
