Product details

Overview

DMV1500L 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 video displays with E/W correction. It integrates a 1500 V damper diode (IF(AV) = 4 A, trr ≤ 170 ns, VF ≤ 1.5 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 DMV1500L datasheet, DMV1500L pinout, DMV1500L application, or DMV1500L equivalent, key selection criteria include verified dual-diode integration, insulated 2000 VRMS barrier, planar-junction fast recovery performance, and conduction loss equations for both sections - critical for CRT flyback and scanning timing design.

Technical Context

The DMV1500L implements two independent silicon planar junction diodes on one die: a high-breakdown 1500 V damper section optimized for energy recycling in CRT horizontal output stages, and a faster 600 V modulation section with sub-50 ns trr for precise E/W correction waveform shaping. Both share thermal coupling but maintain separate anode/cathode terminals.

Its TO-220FPAB package provides electrical insulation (2000 VRMS, 7 pF capacitance) between mounting base and internal leads, enabling direct heatsink mounting without isolation hardware. The F5 bending option (DMV1500LFD5) supports automated insertion while preserving thermal resistance Rth(j-c) = 4.0 °C/W.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM (Damper)	1500 V - Withstands peak reverse voltage in CRT flyback transformer primary during retrace.
VRRM (Modulation)	600 V - Supports E/W correction voltage swing across deflection yoke windings.
trr (Damper)	≤170 ns - Limits switching losses and voltage overshoot during rapid turn-off in 15.6–16.7 kHz horizontal scan.
trr (Modulation)	≤50 ns - Enables clean, low-distortion modulation of horizontal scan current for geometry correction.
VF (Damper @ 4 A)	≤1.5 V - Reduces conduction loss to <1.7 W average under typical triangular IF(AV) = 4 A waveform.
VF (Modulation @ 3 A)	≤1.4 V - Minimizes power dissipation in modulation path during active line period.
Rth(j-c)	4.0 °C/W - Enables direct heatsink mounting with predictable junction temperature rise under 4 A continuous operation.
Insulation rating	2000 VRMS - Eliminates need for insulating washers when mounted to grounded metal chassis.

Pinout & Package

DMV1500L uses the insulated TO-220FPAB package (mechanical outline per Figure 17–19), with metal tab electrically isolated from all terminals. The three-pin configuration supports independent connection of damper and modulation sections.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Damper Cathode)	Damper diode cathode	Connected to flyback transformer primary center tap; carries full horizontal retrace current.
Pin 2 (Damper Anode / Modulation Cathode)	Shared node: damper anode & modulation cathode	Internal connection point; referenced to horizontal output transistor collector and modulation drive return.
Pin 3 (Modulation Anode)	Modulation diode anode	Driven by E/W correction amplifier; shapes horizontal scan current waveform via controlled conduction.

Key Features

Feature	Design Value
Dual-die integration	Single-package co-location of damper and modulation diodes reduces PCB area and interconnect inductance in CRT deflection circuits.
Insulated mounting base	2000 VRMS isolation enables direct heatsink attachment without thermal pads or insulators, simplifying mechanical assembly.
Planar junction technology	Ensures tight parameter distribution (e.g., ±10% VF, ±15% trr) across production lots for consistent horizontal scan timing.
Specified turn-on switching	tfr ≤ 450 ns (damper) and ≤ 240 ns (modulation) ensures minimal delay between drive signal and current conduction in time-critical deflection paths.
Low peak forward voltage	VFP ≤ 36 V (damper @ 4 A, dIF/dt = 80 A/µs) limits voltage spikes during fast switching, reducing snubber component stress.

Equivalent & Alternatives

The following parts are listed as comparable options for similar damper + modulation diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH12R06D	Single 600 V, 12 A ultrafast diode; no integrated damper section or insulation.	Requires discrete damper + modulation pairing and external isolation hardware.	Use only when redesigning layout to separate functions or upgrading current rating beyond 4 A.
BYV26E	600 V, 2.5 A fast recovery diode; no damper capability, non-insulated TO-220AC package.	Limited to modulation-only roles; cannot replace damper function or meet 1500 V requirement.	Suitable only as modulation-only drop-in where damper is implemented separately and chassis grounding permits non-isolated mounting.

Compared with STTH12R06D and BYV26E, DMV1500L uniquely delivers certified dual-function integration, 2000 VRMS insulation, and matched parametric behavior - eliminating inter-device timing skew and reducing BOM count by one device in CRT deflection designs.

FAQ

What is the maximum junction temperature for continuous operation?

The DMV1500L has a rated maximum operating junction temperature of 150 °C, validated across its full absolute maximum ratings envelope. This allows sustained operation at IF(AV) = 4 A (damper) and 3 A (modulation) with proper heatsinking, as confirmed by thermal resistance Rth(j-c) = 4.0 °C/W and derating curves in Figures 2 and 6–7.

Can the DMV1500L be used in non-CRT applications such as SMPS or PFC?

No - the DMV1500L is not characterized or qualified for switch-mode power supply or power factor correction use. Its recovery characteristics, conduction loss equations, and thermal design are optimized for 15–16 kHz horizontal deflection waveforms, not high-frequency PWM operation. Parameter drift above 20 kHz is not specified.

Is the TO-220FPAB package lead-free and RoHS-compliant?

Yes - the DMV1500L was manufactured under STMicroelectronics' standard RoHS-compliant process as of its 2004 release. The TO-220FPAB package uses lead-free terminations and meets EU Directive 2002/95/EC requirements, with full compliance documentation available in ST's official product change notices.

How does the F5 bending option affect thermal performance?

The F5 bending (DMV1500LFD5) modifies lead geometry for automated insertion but does not alter thermal resistance - Rth(j-c) remains 4.0 °C/W. Mechanical data in Figure 19 confirms identical case dimensions and mounting surface contact area, ensuring equivalent heatsink interface performance versus the standard DMV1500LFD variant.
