Product details
Overview
PZTA92 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/−10 V. It serves as a high-voltage switching or amplification element in off-line signal conditioning stages of video and telecom equipment.
For engineers reviewing the PZTA92 datasheet, PZTA92 pinout, PZTA92 application, or PZTA92 equivalent, this page delivers verified electrical parameters, thermal resistance values (Rth(j-a) = 104 K/W), dual-collector pin configuration, and application-specific design guidance for high-voltage analog and switching circuits.
Technical Context
The PZTA92 operates as a medium-speed, low-current PNP BJT optimized for stable DC gain and high breakdown voltage under pulsed conditions (tp ≤ 300 µs, duty δ ≤ 0.02). Its VCE(sat) ≤ −500 mV at IC = −20 mA/IB = −2 mA enables efficient saturation in high-side switch configurations.
Thermal performance is defined for PCB-mounted operation: Rth(j-sp) = 23 K/W to solder point and Rth(j-a) = 104 K/W (FR4, single-sided copper, 1 cm² collector pad). The dual-collector (pins 2 & 4) structure supports enhanced power dissipation and current sharing in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −300 V - Enables direct interface with 230 V AC line-derived rails without external voltage division. |
| IC | −100 mA - Supports moderate-signal switching in video sync generators and telecom ring detectors. |
| hFE | ≥25 at −30 mA/−10 V - Ensures predictable base drive requirements for reliable turn-on in linear and saturated modes. |
| VCE(sat) | ≤ −500 mV - Minimizes conduction loss in high-voltage switching nodes where efficiency impacts thermal margin. |
| Rth(j-a) | 104 K/W - Requires ≥1 cm² copper pour on FR4 for continuous 1.2 W dissipation at Tamb ≤ 25 °C. |
| fT | 50 MHz - Sufficient for video bandwidth (e.g., composite sync pulse shaping) and telephony tone generation. |
Pinout & Package
SOT223 (SC-73) plastic surface-mount package: 6.5 mm × 3.5 mm × 1.65 mm body, 2.3 mm lead pitch, integrated heatsink tab (pin 3 = emitter, pins 2 & 4 = collectors).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input; requires current-limited drive (IBM ≤ −100 mA) to avoid latch-up during fast transitions. |
| 2 | Collector | Primary high-voltage output node; electrically identical to pin 4 for parallel connection or thermal spreading. |
| 3 | Emiter | Reference terminal; connected to PCB ground plane or negative rail; forms thermal path to board copper. |
| 4 | Collector | Secondary high-voltage output node; shares same internal die connection as pin 2-used for layout symmetry or current sharing. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-collector configuration | Enables symmetrical PCB routing and distributed heat transfer across two terminals, improving thermal reliability in space-constrained designs. |
| −300 V VCEO rating | Permits direct use in off-line auxiliary supplies and telephone line interface circuits without series stacking or snubbers. |
| Low leakage (ICBO ≤ −20 nA) | Ensures stable biasing in high-impedance video amplifier stages and prevents false triggering in telecom ring detection. |
| 1.2 W Ptot at Tamb = 25 °C | Supports continuous operation in sealed enclosures up to +75 °C ambient when mounted on ≥1 cm² copper area. |
Applications
| Video Sync Generator | Telephone Ring Detector |
|---|---|
Use Scenario: Generating precise vertical/horizontal sync pulses in analog video processing units. IC Role / Device Role / Timing Role: PNP high-voltage switch driving CRT deflection coils or timing capacitor discharge paths. Use Value: −300 V rating allows direct connection to flyback-derived HV rails; low VCE(sat) ensures minimal pulse distortion at 15.734 kHz repetition. |
Use Scenario: Detecting 20 Hz–30 Hz AC ring signals on POTS lines while rejecting DC bias and noise. IC Role / Device Role / Timing Role: High-impedance, high-breakdown front-end amplifier stage before rectification and logic-level conversion. Use Value: Low ICBO (≤ −20 nA) prevents false triggers; hFE stability over temperature maintains consistent sensitivity across −25 °C to +70 °C. |
| Professional Audio Mixer Output Stage | Industrial Relay Driver |
Use Scenario: Level-shifting and buffering line-level audio signals into transformer-coupled outputs. IC Role / Device Role / Timing Role: PNP emitter-follower configured for high-voltage swing and low output impedance. Use Value: fT = 50 MHz preserves transient fidelity up to 20 kHz; dual-collector layout reduces thermal stress during sustained 100 mA peaks. |
Use Scenario: Driving 24 V or 48 V industrial relay coils requiring >100 mA peak current and isolation from control logic. IC Role / Device Role / Timing Role: High-voltage saturated switch interfacing microcontroller GPIO to inductive load. Use Value: VCEO = −300 V withstands inductive kickback without clamping diodes; Rth(j-sp) = 23 K/W enables rapid heat transfer to PCB during 100 ms coil energization. |
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 |
|---|---|---|---|
| MPSA92 | VCEO = −300 V, IC = −500 mA, hFE = 25–100, TO-92 package | Higher current capability but larger footprint and lower thermal conductivity (no heatsink tab) | Select when higher IC is required and PCB space permits through-hole mounting. |
| BCP53-16 | VCEO = −45 V, IC = −1 A, hFE = 100–250, SOT-223 package | Lower voltage rating but higher gain and current; unsuitable for off-line voltage domains | Select only for low-voltage (<60 V) switching where gain consistency and saturation voltage are prioritized over breakdown. |
Compared with MPSA92 and BCP53-16, the PZTA92 uniquely balances −300 V capability with SOT223 thermal performance and dual-collector layout-making it optimal for space-constrained, high-voltage analog signal paths where TO-92 thermal limits or low-voltage alternatives fail.

FAQ
What is the maximum continuous collector current for PZTA92?
The absolute maximum continuous collector current (IC) is −100 mA at Tamb ≤ 25 °C with proper PCB heatsinking (1 cm² copper). At higher ambient temperatures or reduced copper area, derating is required per the thermal resistance Rth(j-a) = 104 K/W. Peak current up to −200 mA is allowed for short pulses (tp ≤ 300 µs, duty ≤ 2%).
Can PZTA92 be used as a direct replacement for MPSA92?
No-while both are −300 V PNP transistors, PZTA92 uses SOT223 with dual collectors and 1.2 W power dissipation, whereas MPSA92 is TO-92 packaged with 625 mW rating and single collector. Pinout, thermal behavior, and PCB layout are incompatible; redesign is required for substitution.
What is the significance of pins 2 and 4 being tied internally?
Pins 2 and 4 are internally connected to the same collector region, enabling either parallel connection for improved current handling or symmetric PCB routing to balance thermal gradients. This dual-terminal design enhances thermal dissipation and mechanical stability without altering electrical function.
Does PZTA92 meet automotive qualification standards?
No-per Nexperia's revision history (v.4, October 2024), PZTA92 is explicitly designated as non-automotive qualified. It lacks AEC-Q101 testing and is not warranted for safety-critical or life-support systems. Automotive-grade alternatives must be selected from Nexperia's −Q qualified portfolio.
