Product details
Overview
ZXTP2039FTA from Diodes Incorporated (formerly Zetex Semiconductors) is an 80 V, -1 A PNP silicon planar medium-power transistor in SOT23 package, featuring VCE(sat) < -600 mV at -1 A, hFE ≥ 100 at -1 A, and V(BR)CEO = -60 V, optimized for power MOSFET gate driving in DC-DC converters.
For engineers reviewing the ZXTP2039FTA datasheet, ZXTP2039FTA pinout, ZXTP2039FTA application, or ZXTP2039FTA equivalent, key selection criteria include guaranteed VCE(sat) performance at high IC, thermal derating on FR4 PCBs, complementary pairing with ZXTN2038F, and Pb-free SOT23 compatibility with automated assembly.
Technical Context
This PNP transistor uses a planar epitaxial structure to achieve stable hFE across -1 mA to -2 A and supports pulsed ICM = -2 A with 2% duty cycle. Its V(BR)CEV = -80 V enables robust operation under transient overvoltage conditions in switching nodes.
The device operates from -55 °C to +150 °C junction temperature, with fT = 150 MHz at IC = -50 mA and VCE = -10 V, supporting fast turn-off in gate drive applications where Cobo = 10 pF minimizes Miller feedback.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)CEO | -60 V - Maximum safe DC collector-emitter voltage before breakdown in open-base configuration |
| IC(cont) | -1 A - Continuous collector current rating on 15 mm × 15 mm FR4 PCB with 1 oz copper |
| VCE(sat) | -0.6 V @ -1 A / -100 mA - Confirmed saturation voltage enabling < 600 mW conduction loss at full load |
| hFE | 100 @ -1 A - Minimum DC current gain ensuring reliable base drive sizing for 10:1 IC:IB ratio |
| PD | 350 mW @ TA = 25 °C - Thermal limit requiring derating above 25 °C ambient per published curves |
| fT | 150 MHz - Transition frequency supporting sub-100 ns switching transitions in gate drive circuits |
| Cobo | 10 pF @ VCB = -10 V - Output capacitance directly impacting turn-off delay and Miller plateau duration |
Pinout & Package
SOT23-3 plastic surface-mount package with gull-wing leads; standardized footprint compatible with IPC-7351B SOT23-3A land pattern; moisture sensitivity level (MSL) 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal | Connected to positive rail in high-side switch configurations; requires low-inductance routing to minimize switching overshoot |
| 2 (Base) | Control input | Driven by logic-level or dedicated gate driver; IB = -100 mA required for full saturation at IC = -1 A |
| 3 (Collector) | Current sink terminal | Connected to MOSFET gate; polarity reversal relative to NPN mandates inverted drive signal timing |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | ≤ -600 mV at -1 A reduces conduction loss by >30% vs. standard PNP transistors in gate drive paths |
| High hFE stability | hFE ≥ 100 up to -1 A enables single-stage drive without Darlington stacking |
| Pb-free SOT23 | RoHS-compliant lead finish and reflow profile compatible with standard SnPb and lead-free assembly processes |
| Complementary pair | Matched performance with ZXTN2038F (NPN) simplifies dual-rail gate driver design and layout symmetry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBT2907ALT1G | V(BR)CEO = -60 V, VCE(sat) = -1.6 V @ -500 mA - higher saturation voltage, lower fT (200 MHz but measured at lower IC) | Limited to ≤ 500 mA continuous; unsuitable for 1 A gate drive without parallel devices | Select when cost sensitivity outweighs conduction loss and board space is constrained |
| PN2907A | TO-92 package, PD = 625 mW - larger footprint, higher thermal resistance, no SMT compatibility | Not suitable for high-density or automated assembly; requires manual soldering or through-hole rework | Choose only for prototyping or legacy repair where SOT23 footprint is unavailable |
Compared with MMBT2907ALT1G and PN2907A, ZXTP2039FTA delivers superior 1 A saturation performance in SOT23, enabling compact, high-efficiency gate drive stages without thermal compromise or layout redesign.

FAQ
What is the maximum allowable base current for ZXTP2039FTA?
The absolute maximum peak base current is -1 A per datasheet Absolute Maximum Ratings. For reliable continuous operation at IC = -1 A, the recommended base drive is -100 mA to ensure full saturation while staying within SOA limits and avoiding second breakdown.
Can ZXTP2039FTA replace a standard 2N2907 in SOT23 form factor?
No - ZXTP2039FTA is not a direct replacement for 2N2907 due to significantly higher current capability (-1 A vs. -600 mA), lower VCE(sat) (-0.6 V vs. -1.6 V), and tighter hFE distribution. Circuit redesign is required to avoid overdriving the base or exceeding SOA under transient conditions.
Is ZXTP2039FTA suitable for linear regulator pass transistor applications?
It is not recommended for linear regulation. The device lacks guaranteed Safe Operating Area (SOA) data in linear mode, and its 350 mW power dissipation rating assumes switching operation with low duty-cycle heating. Continuous linear operation risks thermal runaway without external current limiting and heatsinking.
Does ZXTP2039FTA have SPICE model support?
Yes - Diodes Incorporated provides verified SPICE parameter data upon request, including Gummel-Poon model coefficients extracted from measured fT, Cobo, and VCE(sat) characteristics. Model accuracy is validated for transient simulations up to 100 MHz.
