Product details
Overview
ZXTN26070CV-7 from Diodes Incorporated is a 70V NPN low-saturation transistor in SOT-666 package, rated for 2.0A continuous collector current and 5A peak pulse current, with VCE(sat) < 30mV at 100mA and Rsat = 130mΩ, used in high-efficiency DC-DC converter switching stages and automotive load switching.
For engineers reviewing the ZXTN26070CV-7 datasheet, ZXTN26070CV-7 pinout, ZXTN26070CV-7 application, or ZXTN26070CV-7 equivalent, key selection criteria include VCEO = 70V, IC = 2A, VCE(sat) ≤ 147mV @ 1A/50mA, thermal resistance RθJL = 37°C/W, and SOT-666 six-terminal configuration with dual emitter-collector paralleling capability.
Technical Context
This NPN transistor features a planar epitaxial die structure optimized for low saturation voltage and fast switching (ton = 46ns, toff = 722ns), supporting high-duty-cycle operation up to 150°C junction temperature. Its BVCEO = 70V and BVCBO = 150V enable robust blocking in 48V automotive and industrial power rails.
The SOT-666 package integrates four terminals (pins 1,2,5,6) as parallel-connected collectors and pins 3 and 4 as base and emitter respectively, enabling low Rsat and distributed thermal dissipation. Thermal resistance from junction to lead is 37°C/W, confirming direct heat path design for PCB-mounted thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 70 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration |
| IC (continuous) | 2.0 A - Continuous DC current handling capacity under 25°C ambient with defined PCB copper area |
| VCE(sat) | 22 mV @ 0.1A/10mA - Ultra-low on-state voltage enabling <30mW conduction loss at light loads |
| Rsat | 130 mΩ - Equivalent on-resistance derived from VCE(sat)/IC, critical for thermal design in high-current switches |
| RθJL | 37 °C/W - Junction-to-lead thermal resistance confirms efficient heat transfer to PCB via collector leads |
| fT | 200 MHz - Transition frequency supports stable linear amplification and fast digital switching |
| toff | 722 ns - Turn-off delay enables use in PWM frequencies up to ~300 kHz without excessive switching loss |
Pinout & Package
SOT-666 is a 6-pin, surface-mount plastic package with dual collector terminals (pins 1,2,5,6), single base (pin 3), and single emitter (pin 4); total weight 0.004 g, UL 94V-0 rated molding compound, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Collector (parallel-connected) | Four dedicated collector terminals reduce current density and thermal resistance per bond wire |
| 3 | Base | Control input requiring 10–100 mA drive for full saturation at 1–2 A output |
| 4 | Emitter | Common emitter reference node; tied to ground or low-side return path in switch configurations |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | 22 mV @ 0.1A/10mA enables sub-30 mW conduction loss in battery-powered load switches |
| Dual collector architecture | Four collector terminals (pins 1,2,5,6) lower effective Rsat and improve thermal derating margin |
| AEC-Q101 readiness | Manufactured in IATF 16949 certified facilities; PPAP-capable for automotive-grade change control |
| Green compound | Halogen- and antimony-free molding compound (<900 ppm Br, <900 ppm Cl, <1000 ppm Sb) meets global environmental mandates |
Applications
| Automotive LED Headlamp Driver | Industrial 48V DC-DC Converter Switch |
|---|---|
Use Scenario: High-side switching of 3A LED strings in adaptive front-lighting systems with PWM dimming up to 2 kHz. IC Role / Device Role / Timing Role: NPN power switch controlling current path between 48V rail and LED cathode, driven by MCU GPIO via base resistor network. Use Value: VCEO = 70V provides 20V headroom above 48V nominal rail; Rsat = 130mΩ limits conduction loss to <1.2W at 3A, reducing heatsink requirements. | Use Scenario: Low-side synchronous rectifier in 400kHz buck converter delivering 2.5A at 12V from 48V input. IC Role / Device Role / Timing Role: Fast-switching NPN transistor replacing Schottky diode in freewheeling path to reduce forward drop and improve efficiency. Use Value: toff = 722ns allows clean turn-off within 2.5μs dead-time window; VCE(sat) ≤ 147mV @ 1A cuts conduction loss by >60% vs. 0.45V Schottky. |
| Smart Power Outlet Load Switch | Medical Infusion Pump Motor Driver |
Use Scenario: Solid-state replacement for electromechanical relay in Class II AC/DC-powered smart outlets controlling resistive/heating loads up to 1.8A. IC Role / Device Role / Timing Role: High-reliability NPN switch isolating load from 5V logic-controlled gate driver, with integrated ESD protection on base terminal. Use Value: IC = 2A continuous rating supports 21.6W load at 12V; RθJL = 37°C/W enables direct thermal coupling to copper pour without external heatsink. | Use Scenario: H-bridge half-bridge leg driving 12V brushed DC motor in battery-operated infusion pump with stall detection. IC Role / Device Role / Timing Role: Low-loss NPN switch in motor phase leg, operated with complementary PWM to minimize shoot-through risk and conduction heating. Use Value: BVCBO = 150V prevents breakdown during inductive flyback spikes; hFE ≥ 190 @ 10mA ensures reliable saturation with minimal base drive current. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN low-saturation transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN25045DFH-7 | VCEO = 45V, IC = 3A, VCE(sat) = 25mV @ 0.1A/10mA, SOT-23-3 package | Limited to ≤36V systems; lacks parallel collector terminals and thermal performance of SOT-666 | Select when board space is constrained and voltage stress remains below 40V |
| MMDT2907A-7-F | VCEO = 60V, IC = 0.6A, VCE(sat) = 100mV @ 0.15A/15mA, SOT-363 package | Lower current and higher saturation voltage; suitable only for signal-level or low-power switching | Choose only for bias networks or low-current logic interface, not power switching |
Compared with ZXTN26070CV-7, ZXTN25045DFH-7 trades voltage headroom for higher current and smaller footprint, while MMDT2907A-7-F offers dual-device integration but cannot support >600mA loads or 70V blocking-making ZXTN26070CV-7 uniquely suited for 48V+ industrial switching where low Rsat and thermal robustness are mandatory.

FAQ
What is the maximum allowable junction temperature for ZXTN26070CV-7?
The absolute maximum junction temperature is +150°C, with continuous operation supported from –55°C to +150°C. Derating begins at +25°C ambient based on RθJA = 121°C/W (on 25mm × 25mm × 1.6mm FR4 with 2 oz copper), allowing 0.83W max power at +85°C ambient.
Can ZXTN26070CV-7 be used in avalanche mode?
No-ZXTN26070CV-7 is not rated or characterized for repetitive avalanche operation. Its safe operating area (SOA) curve shows no second breakdown region, and datasheet specifications assume operation within the DC and pulsed SOA boundaries without energy-limiting external components.
How are pins 1, 2, 5, and 6 electrically connected internally?
Pins 1, 2, 5, and 6 are bonded directly to the same collector region of the silicon die and are shorted together internally. This configuration reduces effective current density per terminal and lowers overall package inductance and thermal resistance compared to single-collector packages.
Is ZXTN26070CV-7 compliant with AEC-Q101 stress testing?
ZXTN26070CV-7 is manufactured in IATF 16949-certified facilities and supports PPAP documentation; however, it is not formally qualified to AEC-Q101. Customers requiring AEC-Q101 must contact Diodes Incorporated directly for qualification status and change control procedures.
