Product details

Overview

HD1760JL from STMicroelectronics is a very high voltage NPN power transistor designed for horizontal deflection stages in high-definition and slim CRT displays, featuring V_CES = 1700 V, I_C = 36 A, P_TOT = 200 W at T_C = 25°C, R_thJC = 0.625 °C/W, and optimized for 32 kHz/100 kHz inductive switching in flyback operation.

For engineers reviewing the HD1760JL datasheet, HD1760JL pinout, HD1760JL application, or HD1760JL equivalent, key selection criteria include sustained V_CEO(sus) = 800 V under pulsed conditions, V_CE(sat) = 2 V at I_C = 18 A / I_B = 4.5 A, and thermal performance validated for CRT horizontal output stage reliability across -55°C to 150°C junction range.

Technical Context

This transistor implements ST's Enhanced High Voltage Structure 1 (E.H.V.S.1) with diffused collector planar technology, enabling stable gain (h_FE = 5–30 at I_C = 2 A; 8.5 at I_C = 18 A) and low saturation voltages across wide temperature variation. It supports high-frequency inductive switching with t_s = 2.0–2.6 µs and t_f = 110–300 ns under defined flyback test conditions (V_CE(fly) = 1300–1340 V, L_BB(on) = 0.25–0.8 µH).

The device operates in reverse-biased safe operating area (SOA) with V_CEO(sus) = 800 V at I_C = 10 mA, and exhibits low leakage: I_CES ≤ 2 mA at V_CE = 1700 V / T_J = 125°C, and I_EBO ≤ 10 µA at V_EB = 5 V - critical for CRT deflection stability under high-voltage transients.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CES	1700 V - maximum blocking voltage with base open; defines absolute limit for CRT flyback energy recovery
V_CEO(sus)	800 V - sustaining voltage under pulsed 300 ms / ≤1.5% duty cycle; ensures reliable retrace timing margin
I_C / I_CM	36 A / 54 A - continuous and peak collector current; supports 110–130 W horizontal output power
V_CE(sat)	2 V at I_C = 18 A, I_B = 4.5 A - low conduction loss enabling >85% efficiency in resonant deflection
R_thJC	0.625 °C/W - thermal resistance from junction to case; enables 200 W dissipation with minimal heatsink mass
h_FE	8.5 at I_C = 18 A - DC current gain sufficient for direct drive from low-impedance driver ICs without bootstrapping
t_s/t_f	2.0 µs / 110 ns (100 kHz); 2.6 µs / 300 ns (32 kHz) - verified switching times for CRT linearity and geometry control

Pinout & Package

HD1760JL is housed in a TO-264 (ISOWATT218) package - a single-ended, isolated-tab, through-hole power package with 3 terminals and integral metal tab for direct heatsink mounting. The case is electrically connected to the collector.

Pin/Terminal	Circuit Role	Design Meaning
1 (Tab)	Collector (case-connected)	Primary high-voltage node; requires insulated mounting hardware and ≥1700 V creepage clearance
2	Base	Low-impedance control input; driven by dedicated horizontal driver IC (e.g., STV9302) with ±6.9 A peak sink capability
3	Emitter	Reference node for deflection yoke return path; carries full horizontal scan current with minimal parasitic inductance

Key Features

Feature	Design Value
Enhanced High Voltage Structure 1 (E.H.V.S.1)	Enables 1700 V V_CES with controlled avalanche behavior and reduced secondary breakdown risk in CRT flyback
Diffused collector planar process	Delivers stable h_FE and low V_CE(sat) across -55°C to 150°C, minimizing geometry drift in ambient-variable displays
ECOPACK® lead-free second-level interconnect	Complies with JEDEC JESD97 marking; supports RoHS-compliant reflow and manual soldering per ST's specified thermal profile
Reverse-biased SOA validation	Guaranteed operation up to 800 V / 10 mA with defined pulse conditions - critical for CRT retrace voltage clamping integrity

Applications

High-Definition CRT Television

Slender CRT Monitor

Use Scenario: Horizontal deflection stage in 100+ Hz interlaced or progressive-scan CRT TVs requiring precise linearity and minimal pincushion distortion.

IC Role / Device Role / Timing Role: Main switch in resonant flyback topology; handles 15.734 kHz (NTSC) or 15.625 kHz (PAL) horizontal scanning with 300–500 V flyback spikes.

Use Value: V_CES = 1700 V and R_thJC = 0.625 °C/W enable compact heatsinking while sustaining 110 W average output power over 10-year field life.

Use Scenario: Slim-profile CRT monitor with reduced depth, demanding higher efficiency and tighter thermal management in horizontal output stage.

IC Role / Device Role / Timing Role: High-speed switching element in quasi-resonant horizontal deflection circuit operating at 32 kHz for improved geometry correction.

Use Value: Verified t_s/t_f = 2.0 µs / 110 ns at 100 kHz ensures <0.5% linearity error and eliminates S-correction capacitor dependency.

Professional Broadcast Monitor

Medical Imaging CRT Display

Use Scenario: High-stability broadcast-grade monitor requiring zero geometry shift across 0–40°C ambient and 24/7 operation.

IC Role / Device Role / Timing Role: Primary horizontal output transistor with tight h_FE tolerance (5–30) and low I_CES drift (<2 mA @ 125°C) for consistent beam positioning.

Use Value: Stable gain and leakage ensure <±0.1% raster size variation over temperature - meeting SMPTE RP 168 compliance thresholds.

Use Scenario: Diagnostic CRT display in ultrasound or X-ray systems where image fidelity and timing repeatability are safety-critical.

IC Role / Device Role / Timing Role: Deflection switch operating in reverse-biased SOA mode during flyback to guarantee pixel-perfect scan timing under load transients.

Use Value: Validated V_CEO(sus) = 800 V at 300 ms pulse ensures no timing jitter or beam collapse during high-energy burst imaging sequences.

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
BU508AF	V_CES = 1500 V (200 V lower); h_FE = 6–20; R_thJC = 0.75 °C/W	Lower voltage margin reduces design headroom for CRT flyback overshoot; requires larger heatsink for same power	Acceptable only if system flyback voltage is confirmed ≤1400 V and thermal budget allows +20% case rise
2SD2578	V_CES = 1700 V (same); I_C = 25 A (11 A lower); V_CE(sat) = 2.5 V at rated current	Reduced current rating limits max deflection power to ~85 W; higher saturation loss increases thermal stress	Only suitable for legacy 14–15" monitors with ≤90 W horizontal output requirement

Compared with BU508AF and 2SD2578, HD1760JL delivers superior voltage margin, higher current capability, and lower thermal resistance - making it the preferred choice for 21"+ HD CRTs where flyback energy and thermal density are most demanding.

FAQ

Is HD1760JL still in active production?

No - HD1760JL is marked "Obsolete Product(s)" in ST's official documentation (Rev 3, June 2007). However, Aetrix Electronics maintains legacy inventory with full traceability and offers engineering support for redesign evaluation, including parametric matching and thermal derating guidance for drop-in replacement assessment.

What is the recommended gate/base drive configuration for HD1760JL?

HD1760JL requires active base drive with peak sink current ≥6.9 A (per datasheet t_f test condition). ST recommends pairing it with dedicated horizontal drivers such as STV9302 or TDA9102, using low-inductance PCB layout, separate emitter return traces, and fast-recovery base clamping diodes to minimize storage time.

Can HD1760JL be used in modern LCD or OLED backlight inverters?

No - HD1760JL is optimized for CRT horizontal deflection's unique combination of high-voltage flyback, inductive load switching, and precise timing control. Its safe operating area, saturation characteristics, and thermal profile do not align with CCFL or LED driver requirements, which demand different voltage/current ratios and PWM control interfaces.

Does HD1760JL require a heatsink, and what mounting torque is specified?

Yes - mandatory heatsinking is required due to 200 W total dissipation. ST specifies M3.5 screw mounting with 0.7–0.9 N·m torque for TO-264 packages. Thermal interface material must be rated for ≥150°C continuous operation, and mechanical isolation (e.g., mica washer + silicone grease) is required since the collector is tied to the metal tab.
