Product details

Overview

HD1530JL from STMicroelectronics is a high-voltage NPN power transistor designed for horizontal deflection output stages in digital TV, HDTV, and high-end CRT monitors. It features 1500 V V_CES, 26 A I_C, 200 W P_TOT, 0.625 °C/W R_thJC, and Enhanced High Voltage Structure (EHVS1) with diffused collector planar technology.

For engineers reviewing the HD1530JL datasheet, HD1530JL pinout, HD1530JL application, or HD1530JL equivalent, key selection criteria include sustained 700 V V_CEO(SUS) at 10 mA, 2.5 V V_CE(sat) at 13 A/3.25 A drive, 1.5 V V_BE(sat), and fast switching performance (1.5 μs t_s, 110 ns t_f) under 100 kHz inductive load conditions.

Technical Context

This device implements an EHVS1-enhanced planar diffused-collector structure optimized for high-repetition-rate horizontal deflection in super-slim CRT displays. Its design delivers stable gain (h_FE = 5–28 across 1–13 A) and low saturation voltages even under wide temperature variation (T_J up to 150 °C).

It operates with pulsed conditions (300 μs, ≤1.5% duty cycle) and supports inductive switching at 32–100 kHz using controlled base drive (IB(on)/IB(off) up to ±6.7 A). Thermal resistance of 0.625 °C/W enables high-power dissipation with minimal case-to-junction delta-T.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	1500 V - Maximum collector-emitter blocking voltage with base open, critical for CRT flyback safety margin
V_CEO(SUS)	700 V - Sustaining voltage at 10 mA collector current, defines reliable operation under dynamic load stress
I_C / I_CM	26 A continuous / 40 A peak - Supports high-current horizontal scan pulses without thermal runaway
V_CE(sat)	2.5 V @ 13 A / 3.25 A - Low conduction loss enabling efficient energy transfer in deflection yoke circuits
t_s / t_f	1.5 μs / 110 ns @ 100 kHz - Fast storage/fall times reduce switching losses during high-frequency retrace
R_thJC	0.625 °C/W - Enables 200 W dissipation with modest heatsinking, essential for compact CRT chassis layouts
h_FE	5–28 @ 1–13 A - Wide DC gain range ensures stable base drive design across production lots and temperature

Pinout & Package

HD1530JL is housed in a TO-264 (ISOWATT218) package with isolated metal tab, rated for high-voltage isolation and direct heatsink mounting. Pin 1 = Collector (tab), Pin 2 = Base, Pin 3 = Emitter - confirmed per Figure 1 and internal schematic (Fig. 2) in STMicroelectronics preliminary data sheet rev.1 (July 2005).

Pin/Terminal	Circuit Role	Design Meaning
1 (Tab)	Collector	Electrically connected to metal case; requires insulated mounting when referenced to non-ground potentials
2	Base	Low-impedance control input; accepts ±6.7 A peak drive for fast turn-on/turn-off in deflection timing
3	Emitter	Power return path; referenced to ground in standard quasi-resonant horizontal output stage topologies

Key Features

Feature	Design Value
Enhanced High Voltage Structure (EHVS1)	Diffused collector planar process enabling 1500 V V_CES while maintaining robust safe operating area (SOA)
Wide drive condition tolerance	Stable switching performance across 32–100 kHz with varying IB(on)/IB(off) ratios, easing driver IC selection
Reduced temperature sensitivity	h_FE and V_CE(sat) remain within spec from –65 °C to 150 °C junction, minimizing thermal drift in sealed CRT enclosures
High peak current capability	40 A I_CM supports surge currents during linearity correction and pincushion compensation transients

Applications

HDTV CRT Scan Output Stage

Use Scenario: Driving deflection yoke in 1080i/720p digital TV CRT chassis with quasi-resonant flyback topology.

IC Role / Device Role / Timing Role: Primary horizontal output switch; conducts line-time current, then sustains high V_CE during retrace.

Use Value: 700 V V_CEO(SUS) and 1.5 μs t_s ensure clean flyback pulse generation and reduced yoke ringing.

Use Scenario: High-frequency horizontal scanning in wide-aspect HDTV CRTs requiring >48 kHz line rate stability.

IC Role / Device Role / Timing Role: Power switch in resonant horizontal output stage; handles 100 kHz switching with low t_f (110 ns).

Use Value: 0.625 °C/W R_thJC and 200 W P_TOT allow sustained operation without derating in thermally constrained chassis.

High-End Monitor CRT Driver

Super-Slim CRT Display Output

Use Scenario: Precision horizontal deflection in professional broadcast monitors with tight geometry and linearity specs.

IC Role / Device Role / Timing Role: Main switching element in regulated deflection supply; modulates current via base drive timing.

Use Value: 26 A I_C and 28 max h_FE enable accurate current control across brightness and geometry adjustments.

Use Scenario: Compact CRT chassis where thermal mass and board space are severely limited.

IC Role / Device Role / Timing Role: High-efficiency horizontal output transistor with integrated thermal path via TO-264 isolated tab.

Use Value: TO-264 package allows direct heatsink mounting with <1.0 °C/W total thermal path, critical for slim-profile thermal management.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage horizontal deflection transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BU508A	V_CES = 1500 V, but V_CEO(SUS) = 700 V same; lower I_C = 15 A, higher R_thJC = 1.0 °C/W	Less suitable for >40 kHz operation due to slower t_f (300 ns) and reduced SOA at high T_J	Acceptable for legacy 32 kHz CRT designs with conservative thermal design
2SD2579	V_CES = 1500 V, I_C = 25 A, but h_FE min = 3 - narrower gain range and higher V_CE(sat) (3.0 V)	Requires stronger base drive and larger heatsink; less tolerant of temperature variation in sealed enclosures	Preferred only where second-source qualification mandates Toshiba lineage

Compared with BU508A and 2SD2579, HD1530JL offers superior thermal efficiency (0.625 vs ≥1.0 °C/W), tighter h_FE spread (5–28), and faster switching at 100 kHz - making it optimal for next-generation slim CRT deflection stages demanding reliability and compactness.

FAQ

Is HD1530JL still in active production?

No - HD1530JL is marked "Obsolete Product(s)" in STMicroelectronics' official preliminary data sheet (rev.1, July 2005). Aetrix Electronics maintains legacy inventory with full traceability and provides engineering support for repair, refurbishment, and end-of-life system sustainment.

What is the maximum safe operating frequency for HD1530JL in horizontal deflection?

HD1530JL is characterized up to 100 kHz under inductive load (Table 4), with verified t_s/t_f of 1.5 μs/110 ns at that frequency. Operation beyond 100 kHz is not validated and risks exceeding SOA limits due to increased switching losses and thermal stress.

Can HD1530JL be mounted directly to a heatsink without insulation?

No - Pin 1 (collector) is electrically connected to the metal tab. Direct mounting requires electrically isolating hardware (e.g., mica washer + silicone grease) unless the heatsink is fully floating or referenced to collector potential in the circuit topology.

What base drive current is required for reliable saturation at full load?

At I_C = 13 A, datasheet specifies I_B = 3.25 A for V_CE(sat) ≤ 2.5 V. For robust operation across temperature and unit variance, design for ≥4 A peak base current with fast turn-off (–6.7 A) to minimize storage time and prevent secondary breakdown.
