Product details
Overview
PZTA92/ZLX from Nexperia is a PNP high-voltage bipolar junction transistor in SOT223 (SC-73) package, rated for VCEO = −300 V, IC = −100 mA, and Ptot = 1.2 W at Tamb ≤ 25 °C. It serves as a high-voltage switching or linear amplification device in off-line video signal stages, telephony line interface circuits, and professional communication equipment power control paths.
For engineers reviewing the PZTA92/ZLX datasheet, PZTA92/ZLX pinout, PZTA92/ZLX application, or PZTA92/ZLX equivalent, key selection criteria include verified −300 V collector-emitter blocking capability, confirmed dual-collector SOT223 thermal pad configuration, hFE ≥ 25 at −30 mA, and compatibility with reflow/wave soldering footprints per Nexperia's SC-73 layout guidelines.
Technical Context
The PZTA92/ZLX operates as a single PNP BJT with two physically separate collector terminals (Pins 2 and 4) bonded to an extended copper heatsink tab, enabling enhanced thermal dissipation in high-voltage, low-current switching applications. Its design targets stable DC gain (hFE = 25–100) under pulsed conditions (tp ≤ 300 µs, duty δ ≤ 0.02) at 25 °C ambient.
It features low leakage (ICBO ≤ −20 nA at VCB = −200 V) and moderate fT = 50 MHz, supporting video-frequency amplification and line-driving functions where voltage headroom outweighs speed requirements. The device is non-automotive qualified and intended for industrial, telecom, and consumer video systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −300 V - Enables direct use in 230 V AC line-derived supplies without external snubbers or voltage dividers. |
| IC | −100 mA - Supports low-power switching loads such as relay drivers, LED bias networks, and analog switch control. |
| hFE | 25 min @ VCE = −10 V, IC = −30 mA - Ensures reliable base drive margin for saturated switching in discrete logic interfaces. |
| Ptot | 1.2 W @ Tamb ≤ 25 °C on 1 cm² copper pad - Delivers usable power handling with standard PCB heatsinking, no dedicated heatsink required. |
| Rth(j-sp) | 23 K/W - Junction-to-solder-point thermal resistance confirms effective heat transfer to PCB copper, critical for sustained pulse operation. |
| Cc | 6 pF @ VCB = −20 V - Low collector capacitance preserves bandwidth in video amplifier output stages up to ~50 MHz. |
Pinout & Package
Package: SOT223 (SC-73), 4-lead surface-mount plastic package with integrated heatsink tab (Pin 4 electrically connected to Pin 2 and thermal pad). Dimensions: 6.5 mm × 3.5 mm × 1.65 mm body; 2.3 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input node; requires current-limited drive (IBM ≤ −100 mA peak) to avoid saturation delay or thermal runaway. |
| 2 | Collector (C) | Main high-voltage collector terminal; electrically tied to Pin 4 and thermal pad for simultaneous conduction and heatsinking. |
| 3 | Emiter (E) | Reference/output node; connects to load return or supply rail; polarity inverted vs. NPN (current sinks into emitter). |
| 4 | Collector (C) | Secondary collector terminal; redundant connection to Pin 2 and thermal pad-must be soldered to PCB copper for rated power dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage blocking | VCEO = −300 V enables direct interface with off-line AC/DC front-end circuits without auxiliary clamping. |
| Dual-collector thermal architecture | Pins 2 and 4 both connect to internal collector and thermal pad-ensures mechanical stability and consistent Rth(j-sp) = 23 K/W. |
| Pulsed DC gain consistency | hFE ≥ 25 under pulsed conditions (tp ≤ 300 µs) supports predictable switching timing in burst-mode line drivers. |
| Low leakage performance | ICBO ≤ −20 nA at −200 V ensures minimal standby current in high-impedance video coupling nodes. |
Applications
| Video Signal Amplification | Telephony Line Interface |
|---|---|
Use Scenario: Amplifying composite video signals in CRT monitor deflection circuits and legacy broadcast equipment. IC Role / Device Role / Timing Role: PNP active load and level-shifting stage operating at −12 V to −24 V rails with 1–10 MHz bandwidth requirement. Use Value: −300 V VCEO withstands flyback transients during horizontal deflection; 6 pF Cc maintains flat response to 5 MHz. |
Use Scenario: Driving SLIC (Subscriber Line Interface Circuit) bias networks and ring generator stages in PSTN gateways. IC Role / Device Role / Timing Role: High-side PNP switch controlling −48 V battery feed and AC ringing voltage generation. Use Value: Dual-collector SOT223 configuration handles 100 mA pulsed ring current while maintaining <1.2 W dissipation on standard FR4. |
| Professional Audio Mixer Power Rails | Industrial Control Relay Drivers |
Use Scenario: Regulating negative supply rails (−15 V to −24 V) for op-amp stages in broadcast audio consoles. IC Role / Device Role / Timing Role: Discrete pass transistor in linear regulator topology, delivering stable bias under variable load. Use Value: hFE ≥ 25 ensures adequate loop gain for ±0.5 % regulation accuracy; Rth(j-sp) = 23 K/W prevents thermal drift over 8-hour operation. |
Use Scenario: Switching 24 V DC relays in PLC I/O modules and factory automation panels. IC Role / Device Role / Timing Role: Low-speed, high-voltage switch interfacing microcontroller GPIO to relay coil (1–2 kΩ, 20–50 mA). Use Value: −300 V rating absorbs inductive kickback without snubber; −500 mV VCE(sat) minimizes self-heating at full load. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP high-voltage switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPSA92 | VCEO = −300 V, IC = −500 mA, hFE = 25–100, TO-92 package, Rth(j-a) = 200 K/W | Higher current rating but significantly worse thermal resistance; unsuitable for >100 mA continuous operation without heatsink | Select when board space allows TO-92 and peak current exceeds 100 mA; avoid if PCB heatsinking is primary thermal path. |
| ZTX951 | VCEO = −300 V, IC = −1 A, hFE = 40–120, SOT89 package, Rth(j-a) = 125 K/W | Higher current and gain, but larger footprint and higher thermal resistance than SOT223; no dual-collector configuration | Prefer for designs needing >100 mA average current and can accommodate SOT89 layout; not drop-in for PZTA92/ZLX thermal pad routing. |
Compared with MPSA92 and ZTX951, PZTA92/ZLX uniquely combines −300 V rating, SOT223 thermal efficiency (Rth(j-sp) = 23 K/W), and dual-collector construction-making it optimal for space-constrained, thermally managed 100 mA high-voltage switching where TO-92 or SOT89 layouts are impractical.

FAQ
Is PZTA92/ZLX pin-compatible with PZTA42?
No. PZTA92/ZLX is a PNP transistor with base-collector-emitter-collector pinout (1-B, 2-C, 3-E, 4-C) in SOT223, while PZTA42 is its NPN complement with identical pinout but opposite polarity. They are functional complements-not pin-compatible replacements-and must be used in matched pair designs with reversed biasing and signal flow.
Can PZTA92/ZLX be used in automotive applications?
No. Per Nexperia's revision history (v.4, 20241008), PZTA92/ZLX is explicitly designated as non-automotive qualified. It lacks AEC-Q101 stress testing, automotive temperature range validation (−40 °C to +125 °C), and failure rate reporting required for automotive use. Automotive alternatives must be selected from Nexperia's -Q qualified portfolio.
What is the maximum safe continuous collector current at 70 °C ambient?
At Tamb = 70 °C, derating applies: Ptot drops to ≈0.72 W (1.2 W × [1 − (70−25)/104]). Using VCE(sat) ≈ −500 mV, max continuous IC ≈ 1.44 A is theoretically possible-but absolute maximum IC remains −100 mA per datasheet limiting values. Therefore, continuous IC must not exceed −100 mA regardless of temperature.
Does Pin 4 require a separate PCB trace or can it share the same copper pour as Pin 2?
Pin 4 must be connected to the same large copper pour as Pin 2 and the thermal pad-it is not a signal pin but a structural and thermal extension of the collector. Separating Pin 4 from Pin 2 violates the SC-73 mechanical and thermal design intent and will degrade Rth(j-sp), risking premature thermal failure above 0.5 W dissipation.
