Product details

Overview

DXT696BK-13 from Diodes Incorporated is an 180V NPN medium-power high-gain transistor in TO252 (DPAK) package, rated for 0.5A continuous collector current, 180V V_CEO, and minimum h_FE of 500 at I_C = 100mA. It serves as a high-voltage switching element in voltage regulator circuits, relay drivers, and DC fan control stages.

For engineers reviewing the DXT696BK-13 datasheet, DXT696BK-13 pinout, DXT696BK-13 application, or DXT696BK-13 equivalent, key selection criteria include its 180V breakdown rating, 500+ DC current gain at 100mA, TO252 thermal performance with R_θJC = 14.6°C/W, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This NPN bipolar junction transistor is optimized for high-voltage linear and switching operation up to 180V, with low V_CE(sat) (250mV max at I_C = 200mA, I_B = 5mA) and high f_T of 70MHz. Its gain stability across I_C = 100–200mA supports consistent amplification in Darlington pre-driver stages.

The device features a thermally enhanced TO252 package with exposed collector pad, enabling 3.9W power dissipation on 50mm × 50mm 2oz copper PCBs and R_θJA = 32°C/W under those conditions. ESD robustness includes 4kV HBM and 400V MM ratings per JEDEC standards.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	180 V - Enables use in 120–170V DC bus startup and regulation circuits without derating.
I_C (continuous)	0.5 A - Supports sustained load switching for relays, solenoids, and small DC motors.
h_FE min	500 @ I_C = 100mA - Reduces required base drive current in high-gain amplifier or switch configurations.
V_CE(sat) max	250 mV @ I_C = 200mA - Limits conduction loss to <50mW, critical for thermally constrained designs.
R_θJC	14.6 °C/W - Allows direct thermal path from junction to heatsink via exposed collector pad.
f_T	70 MHz - Supports fast switching in PWM-driven fan controllers and auxiliary power supplies.

Pinout & Package

Package: TO252 (DPAK), surface-mount, with exposed collector pad for thermal and electrical connection. Dimensions conform to AP02002; recommended pad layout per AP02001.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main current output terminal, connected to exposed metal pad	Primary thermal path and high-current return; must be soldered to large copper area for heat dissipation.
Base (B)	Control input for transistor biasing	Receives low-current drive (≤5mA typical) to saturate or cut off the 0.5A collector path.
Emitter (E)	Current reference node, typically grounded	Serves as common return for load current; low-impedance connection essential for stable gain and switching speed.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive applications including engine control modules and body electronics.
Lead-free & halogen-free	Complies with RoHS 2 and meets "Green" definition (<900ppm Br/Cl, <1000ppm Sb).
High V_CEO / low V_CE(sat) combination	Enables efficient high-voltage switching with minimal conduction loss in compact layouts.
Moisture Sensitivity Level 1	Eliminates bake requirements before reflow; compatible with standard SMT assembly processes.

Applications

Voltage Regulator Transistors

Startup Switches

Use Scenario: Linear pass transistor in offline AC/DC auxiliary power supplies delivering 12–24V at ≤300mA.

IC Role / Device Role / Timing Role: NPN series pass element regulating output voltage via feedback-controlled base bias.

Use Value: 180V V_CEO withstands rectified 120VAC peaks; 500+ h_FE minimizes base drive circuit complexity.

Use Scenario: High-side switch energizing primary winding of main SMPS controller during system power-up.

IC Role / Device Role / Timing Role: High-voltage NPN switch initiating power-on sequence before main controller becomes active.

Use Value: 1A I_CM handles inrush; 3.9W PD supports brief high-duty startup pulses without thermal shutdown.

Darlington Replacement

DC Fan Control

Use Scenario: Single-transistor replacement for legacy Darlington pairs in motor driver ICs or discrete logic interfaces.

IC Role / Device Role / Timing Role: High-gain NPN stage providing equivalent current amplification without second-stage delay or saturation penalty.

Use Value: h_FE ≥500 at 100mA eliminates need for cascaded transistors, reducing board space and propagation delay.

Use Scenario: PWM-controlled speed regulation of 24V brushless DC cooling fans in industrial enclosures.

IC Role / Device Role / Timing Role: Low-loss switching element modulating fan supply voltage at 20–30kHz.

Use Value: 70MHz f_T ensures clean switching edges; 250mV V_CE(sat) limits self-heating at 500mA average load.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZTX696STZ	Same V_CEO (180V), but TO92 package; lower I_C (0.3A), no AEC-Q101 qualification.	Limited to low-power, non-automotive linear regulators and signal switching.	Select only when TO252 thermal performance or automotive compliance is not required.
MJD122G	Higher I_C (1.5A), same TO252, but lower h_FE (min 40 @ I_C = 1A) and V_CEO (100V).	Suitable for higher-current, lower-voltage loads like solenoid drivers where gain is less critical.	Choose when load current exceeds 0.5A and voltage stays below 100V; avoid for >120V systems.

Compared with ZTX696STZ and MJD122G, DXT696BK-13 uniquely balances 180V capability, 500+ gain, TO252 thermal efficiency, and AEC-Q101 qualification-making it optimal for space-constrained, high-reliability 100–170V switching applications where both voltage headroom and drive efficiency matter.

FAQ

What is the maximum safe operating voltage for DXT696BK-13 in continuous DC applications?

The absolute maximum collector-emitter voltage (V_CEO) is 180V at T_A = +25°C. For reliable long-term operation, design margin recommends limiting steady-state V_CE to ≤144V (80% of rating), especially at elevated ambient temperatures or with reduced PCB copper area.

Does DXT696BK-13 require a heatsink in typical 0.3A switching applications?

Not necessarily: with 50mm × 50mm 2oz copper, R_θJA = 32°C/W allows ~2.1W dissipation at ΔT = 67°C rise. At 0.3A and 200mV V_CE(sat), power is only 60mW - well within safe limits without added heatsinking. Use thermal simulation if PCB copper is reduced or ambient exceeds 70°C.

Can DXT696BK-13 replace a Darlington pair in a 24V relay driver?

Yes - its h_FE ≥500 at I_C = 100mA provides comparable current gain to many Darlington configurations. Verify base drive capability: with 5mA base current, it delivers ≥2.5A theoretical I_C, exceeding typical 24V relay coil currents (20–100mA). Ensure V_CE(sat) remains low under actual load.

Is the exposed collector pad electrically isolated or tied to the collector terminal?

The exposed pad is internally connected to the collector terminal and must be soldered to a PCB copper pour designated as the collector net. It is not isolated - using it as ground or emitter will cause immediate device failure. Thermal vias beneath the pad must connect only to the collector net plane.
