Product details
Overview
PZTA92-Q from Nexperia is a PNP high-voltage bipolar junction transistor in SOT223 (SC-73) package, rated for VCEO = −300 V and IC = −100 mA, with hFE ≥ 25 at −30 mA, designed for high-voltage switching and amplification in video signal stages and telecom line interfaces.
For engineers reviewing the PZTA92-Q datasheet, PZTA92-Q pinout, PZTA92-Q application, or PZTA92-Q equivalent, key selection criteria include verified −300 V collector-emitter breakdown, AEC-Q101 qualification for automotive use, thermal resistance Rth(j-sp) = 23 K/W, and dual-collector SOT223 pin configuration supporting enhanced power dissipation in space-constrained designs.
Technical Context
This PNP transistor operates in common-emitter configuration with open-base VCEO limiting at −300 V and peak collector current ICM = −200 mA. Its DC current gain hFE is specified under pulsed conditions (tp ≤ 300 µs, duty δ ≤ 0.02) to minimize self-heating effects during high-voltage transient handling.
Thermal design relies on solder-point conduction: Rth(j-sp) = 23 K/W enables stable operation up to Tj = 150 °C when mounted on FR4 PCB with 1 cm² collector pad. The dual-collector (pins 2 & 4) structure improves heat spreading versus standard SOT223 devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −300 V: Maximum safe collector-emitter voltage with base open; enables use in 200–250 V rail video output stages. |
| IC | −100 mA continuous: Supports linear amplification or switching loads up to ~3 W at moderate voltage swing. |
| hFE | ≥25 at −30 mA / −10 V: Ensures reliable base drive margin for low-power control circuits without excessive IB overhead. |
| VCE(sat) | ≤ −500 mV at −20 mA / −2 mA: Minimizes conduction loss in saturated-switch applications like relay drivers. |
| Rth(j-sp) | 23 K/W: Junction-to-solder-point thermal resistance confirms effective heat transfer to PCB copper, critical for sustained high-voltage operation. |
| fT | 50 MHz: Transition frequency supports video bandwidth and fast telephony signal switching without phase distortion. |
| AEC-Q101 | Qualified: Validated for automotive temperature cycling, humidity, and mechanical stress per discrete semiconductor standard. |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package with 4 leads, 2.3 mm pitch, 6.5 mm × 3.5 mm × 1.65 mm body, featuring two collector terminals (pins 2 and 4) for improved thermal and current-handling capability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal; requires negative bias relative to emitter to forward-bias base-emitter junction. |
| 2 | Collector (C) | Primary high-voltage current sink; electrically tied to pin 4 for parallel current sharing and thermal spreading. |
| 3 | Emiter (E) | Reference terminal; connected to most positive supply rail in PNP high-side switch configurations. |
| 4 | Collector (C) | Secondary collector terminal; identical function to pin 2-used jointly to reduce current density and thermal resistance. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage blocking | −300 V VCEO rating enables direct interface with CRT anode supplies and telecom line voltages without external snubbers. |
| Dual-collector thermal architecture | Pins 2 and 4 both serve as collectors, lowering effective Rth(j-a) by distributing heat across larger PCB copper area. |
| AEC-Q101 qualification | Validated for automotive ambient range (−65 °C to +150 °C) and reliability stress tests-suitable for infotainment power stages. |
| Low leakage performance | ICBO ≤ −20 nA at −200 V ensures minimal standby current in high-impedance video coupling networks. |
Applications
| Video Output Stage | Telecom Line Interface |
|---|---|
Use Scenario: Amplifying composite video signals to drive 75 Ω coaxial cable in broadcast equipment. IC Role / Device Role / Timing Role: PNP emitter-follower buffer providing high-voltage swing (>200 Vpp) and low output impedance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP high-voltage transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD127 | TO-220 package; higher IC = −800 mA but lower VCEO = −100 V; no AEC-Q101 qualification. | Suitable for industrial power supplies but not automotive or high-voltage video where >200 V blocking is required. | Select when higher continuous current is needed and voltage stress remains below 100 V. |
| PN2907A | SOT-23 package; VCEO = −60 V, IC = −600 mA; unqualified for automotive; Rth(j-a) ≈ 300 K/W. | Applicable only in low-voltage logic-level switching; insufficient for telecom or video signal integrity. | Choose only for cost-sensitive, low-power, non-automotive consumer electronics with <60 V rails. |
Compared with MJD127 and PN2907A, PZTA92-Q uniquely combines −300 V blocking, AEC-Q101 compliance, and SOT223 thermal performance-making it the sole option for space-constrained, high-reliability, high-voltage analog signal paths in automotive and professional equipment.

FAQ
What is the maximum safe operating voltage for PZTA92-Q in DC applications?
The absolute maximum collector-emitter voltage (VCEO) is −300 V with base open, per IEC 60134 limiting values. For reliable long-term operation, design should maintain ≤80% of this rating (i.e., ≤−240 V) under worst-case temperature and transients, especially in automotive environments where load-dump spikes may occur.
Can PZTA92-Q be used as a direct replacement for PZTA42-Q?
No-PZTA42-Q is its NPN complement, not a functional replacement. Swapping them would invert circuit polarity and likely cause failure. They share the same SOT223 package and voltage/current ratings but opposite conduction direction; correct usage depends on whether the application requires sourcing (NPN) or sinking (PNP) current at high voltage.
How does the dual-collector configuration affect PCB layout?
Pins 2 and 4 must be connected to the same high-current copper pour-ideally a single thermal pad-to realize the specified Rth(j-sp) = 23 K/W. Splitting these pins across separate traces degrades thermal performance and risks localized overheating; the footprint in Figure 2 (reflow soldering) shows recommended 1 cm² collector land geometry.
Is PZTA92-Q suitable for linear amplifier applications?
Yes-its hFE ≥25 at −30 mA and low VCE(sat) support Class-A and AB operation in high-voltage analog stages. However, due to limited fT (50 MHz), it is best suited for baseband video (<10 MHz) and audio applications-not RF or high-speed digital switching where gain-bandwidth trade-offs become critical.
