Product details
Overview
ZXTD717MCTA from Diodes Incorporated is a dual PNP low-saturation transistor in W-DFN3020-8 package, designed for high-efficiency power switching in compact DC-DC converters and motor drives. It delivers -4 A continuous collector current per channel, -140 mV VCE(sat) at -1 A, 60 mΩ equivalent on-resistance, and hFE ≥ 300 at -10 mA - enabling space-constrained, thermally demanding automotive and industrial power stages.
For engineers reviewing the ZXTD717MCTA datasheet, ZXTD717MCTA pinout, ZXTD717MCTA application, or ZXTD717MCTA equivalent, key selection criteria include dual-channel PNP saturation performance under high-current pulsed loads, thermal resistance (RθJA = 51.0 °C/W on 28 mm × 28 mm 2 oz Cu), and footprint compatibility with space-limited board layouts requiring <6 mm² area.
Technical Context
This dual PNP transistor integrates two independent high-gain, low-VCE(sat) silicon die in a single thermally enhanced W-DFN3020-8 (Type B) package with exposed collector pads. Each channel supports -12 V VCEO, -20 V VCBO, and operates up to +150 °C junction temperature.
It is optimized for synchronous rectification and active load switching where fast turn-on (<70 ns) and turn-off (<130 ns) times, combined with stable hFE across -10 mA to -10 A, ensure predictable gain control and minimal conduction loss in pulse-width modulated power paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -12 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration |
| IC (cont.) | -4 A per channel - Continuous current handling capacity without thermal runaway on standard PCB |
| VCE(sat) | -140 mV @ -1 A / -10 mA - Low conduction loss enabling >95% efficiency in 12 V power switches |
| RSAT | 60 mΩ - Equivalent on-resistance directly determining I²R heating in high-current paths |
| hFE | 300 min @ -10 mA - Sufficient DC current gain to drive with low-base-current controllers |
| fT | 100 MHz - Supports switching above 1 MHz in high-frequency DC-DC topologies |
| RθJA | 51.0 °C/W - Thermal resistance enabling 2.45 W dissipation on 28 mm × 28 mm 2 oz Cu board |
Pinout & Package
Package: W-DFN3020-8 (Type B), 3.0 mm × 2.0 mm × 0.8 mm, thermally enhanced with dual exposed collector pads (C1, C2) on bottom side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B1) | Base of Transistor 1 | Control input for first PNP channel; requires negative bias relative to emitter to turn on |
| 2 (E1) | Emitter of Transistor 1 | High-side reference node; connected to supply rail in high-side switch configurations |
| 3 (C1) | Collector of Transistor 1 | Power output node; electrically and thermally tied to exposed pad for low-inductance, high-current routing |
| 4 (C2) | Collector of Transistor 2 | Second power output node; isolated from C1 but shares thermal pad for dual-channel thermal coupling |
| 5 (E2) | Emitter of Transistor 2 | Independent high-side reference for second channel; enables dual independent switching paths |
| 6 (B2) | Base of Transistor 2 | Independent control input; allows asynchronous or complementary drive of second PNP channel |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP topology | Reduces component count by replacing two discrete SOT-26 transistors while maintaining independent base control |
| Low VCE(sat) | -140 mV at -1 A ensures <140 mW conduction loss per channel - critical for thermal management in sealed enclosures |
| 6 mm² footprint | 50% smaller than TSOT26 - enables dense power stage layout in portable and automotive ECUs |
| RθJA = 51.0 °C/W | 40% lower than SOT26 - improves power density by allowing higher sustained current without forced cooling |
| AEC-Q101 qualified option | Available in automotive-grade variant with PPAP support and IATF 16949 manufacturing - suitable for under-hood applications |
Applications
| DC-DC Buck Converter | Automotive Seat Motor Driver |
|---|---|
Use Scenario: High-efficiency 12 V to 5 V/3.3 V step-down conversion in infotainment head units. IC Role / Device Role / Timing Role: Dual PNP used as synchronous rectifier and high-side switch in integrated controllerless buck stage.

IC Role / Device Role / Timing Role: Dual PNP implements precision current-sense shunt switch and battery disconnect FET. Use Value: hFE ≥ 300 at -10 mA enables accurate 1% current regulation using low-power op-amp feedback. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTD718MCTA | Same W-DFN3020-8 package; -15 V VCEO, -5 A IC, -160 mV VCE(sat) @ -1 A | Higher voltage rating suits 15 V systems; slightly higher saturation voltage increases conduction loss by ~14% | Select when system rail exceeds 12 V or peak current >4 A is required; verify thermal derating on same PCB |
| DMT3005LKQ-7 | Single-channel 30 V PNP in SOT-26; -5 A IC, -200 mV VCE(sat) @ -2 A; no dual integration | Requires two devices and larger board area; lacks thermal coupling between channels | Choose only if legacy SOT-26 footprint must be retained; expect 35% larger layout area and 22% higher RθJA |
Compared with ZXTD717MCTA, ZXTD718MCTA offers higher voltage headroom at minor conduction cost, while DMT3005LKQ-7 sacrifices integration and thermal efficiency for package familiarity - making ZXTD717MCTA optimal for new designs prioritizing miniaturization and thermal performance.

FAQ
What is the maximum continuous collector current per channel for ZXTD717MCTA?
The ZXTD717MCTA supports -4 A continuous collector current per channel when mounted on a 28 mm × 28 mm FR4 PCB with 2 oz copper and operated at TA = +25°C. Derating applies above +25°C ambient, with full power limited to +100°C case temperature per the published derating curve.
Is ZXTD717MCTA pin-compatible with standard SOT-26 dual transistors?
No - ZXTD717MCTA uses the W-DFN3020-8 (Type B) package with 6-pin top-side layout and dual exposed collector pads, differing fundamentally from the 6-pin SOT-26's gull-wing leads and thermal pad placement. PCB redesign is required for migration.
Does ZXTD717MCTA support automotive qualification?
Yes - the ZXTD717MCTA is available in an AEC-Q101 qualified version (ZXTD717MCTA-13) manufactured in IATF 16949 certified facilities, with PPAP documentation support. Standard ZXTD717MCTA is not automotive-qualified unless explicitly ordered with the -13 suffix.
How does the dual-exposed-pad thermal design affect PCB layout?
The W-DFN3020-8 (Type B) package features two separate exposed collector pads (C1 and C2) on the bottom surface. Each must be connected via ≥4 thermal vias (0.3 mm diameter) to internal or bottom-layer copper planes sized per Diodes' recommended pad layout - ensuring RθJA remains ≤51.0 °C/W and preventing localized hot spots.
