Product details
Overview
ZXTP19060CZTA from Diodes Incorporated is a 60V PNP medium-power transistor in SOT89 package, featuring BVCEO = –60V, IC = –4.5A continuous, VCE(sat) < –80mV @ –1A, RCE(sat) = 50mΩ, and PD = 2.4W. It serves as a high-side driver or load disconnect switch in DC-DC converters and motor drive circuits.
For engineers reviewing the ZXTP19060CZTA datasheet, ZXTP19060CZTA pinout, ZXTP19060CZTA application, or ZXTP19060CZTA equivalent, key selection criteria include low-saturation voltage for minimal conduction loss, high current capability with thermal derating clarity, complementary NPN pairing (ZXTN19060CZ), and automotive-grade qualification readiness.
Technical Context
This PNP bipolar junction transistor operates in linear or saturated switching mode with verified reverse-blocking capability (VECX = –7V) and robust ESD tolerance (HBM = 4000V). Its low RCE(sat) and high hFE (200–500 across IC = –100mA to –4.5A) enable efficient current control in power path management.
The device uses an exposed-collector SOT89 thermally enhanced package, with RθJA ranging from 31°C/W (50mm × 50mm 2oz Cu) to 117°C/W (15mm × 15mm 1oz Cu), and RθJL = 4.7°C/W - confirming direct thermal coupling from junction to PCB pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | –60V: Supports 48V rail switching and industrial bus isolation without breakdown. |
| IC (cont.) | –4.5A: Delivers sustained load current for motor gate drivers or DC-DC synchronous rectifier control. |
| VCE(sat) | < –80mV @ –1A: Limits conduction loss to <80mW at 1A, critical for thermal budget in compact layouts. |
| RCE(sat) | 50mΩ: Enables precise on-resistance modeling for power loss simulation in high-side switch designs. |
| PD | 2.4W: Maximum steady-state dissipation with proper PCB copper area; derates linearly per ambient temperature. |
| hFE | 200–500: Ensures stable base drive requirements across operating current range, reducing base current sourcing burden. |
| fT | 180MHz: Supports fast switching transitions in PWM frequencies up to ~1–2MHz with minimal delay. |
Pinout & Package
Package: SOT89 - surface-mount, thermally enhanced outline with exposed collector pad (pin 1), emitter (pin 2), and base (pin 3). Molded green plastic, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Collector) | Main current sink terminal, electrically connected to exposed metal pad | Primary thermal path to PCB; must be soldered to ≥15mm² copper pour for rated power dissipation. |
| Pin 2 (Emitter) | Current source node in PNP configuration | Connected to higher potential rail (e.g., VIN) in high-side switch topology. |
| Pin 3 (Base) | Control input for minority-carrier injection | Requires negative bias relative to emitter; typical drive: –450mA for full saturation at –4.5A IC. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | <–80mV @ –1A enables sub-100mW conduction loss in high-current switching nodes. |
| High IC rating | –4.5A continuous supports 3A–5A load switching without external heatsinking in optimized layouts. |
| Complementary pairing | ZXTN19060CZ NPN counterpart allows matched design of push-pull or H-bridge output stages. |
| Green construction | Halogen- and antimony-free, fully RoHS 3 compliant (<900ppm Br/Cl, <1000ppm Sb), suitable for eco-sensitive programs. |
| ESD robustness | 4000V HBM rating reduces risk of handling damage during assembly and rework. |
Applications
| High-Side Load Switch | DC-DC Converter Control |
|---|---|
Use Scenario: Powering auxiliary subsystems (e.g., sensors, displays) from a main 24V/48V rail with controlled turn-on/turn-off. IC Role / Device Role / Timing Role: PNP high-side switch controlling current flow from supply to load; driven by microcontroller GPIO via base resistor network. Use Value: Low VCE(sat) minimizes voltage drop and self-heating during sustained operation, extending system uptime. |
Use Scenario: Synchronous rectification or pre-regulator stage in non-isolated buck converters operating up to 1MHz. IC Role / Device Role / Timing Role: Active switch in high-side position; leverages fT = 180MHz and fast switching times (td = 24.3ns, tf = 68.2ns). Use Value: RCE(sat) = 50mΩ reduces conduction loss vs. Schottky diodes, improving efficiency by 1–3% at 3–5A loads. |
| Motor Driver Stage | Industrial Load Disconnect |
Use Scenario: Driving small brushed DC motors (e.g., fans, actuators) in HVAC or factory automation controllers. IC Role / Device Role / Timing Role: Single-ended high-side driver enabling bidirectional control when paired with low-side N-channel MOSFET. Use Value: High hFE (≥200 @ –1A) simplifies base drive circuitry and reduces MCU I/O loading. |
Use Scenario: Safe power removal during fault conditions (overcurrent, overtemperature) in programmable logic controllers (PLCs) or power distribution units. IC Role / Device Role / Timing Role: Final-stage isolation element between upstream supply and downstream field I/O modules. Use Value: BVCEO = –60V and ICM = –7A support surge immunity and transient overload handling per IEC 61000-4-5. |
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 |
|---|---|---|---|
| ZXTP2012ZTA | VCEO = –20V, IC = –3A, VCE(sat) = –120mV @ –1A - lower voltage rating and higher saturation voltage. | Suitable only for ≤12V systems; not recommended for 24V+ DC-DC or motor drive where ZXTP19060CZTA's –60V rating provides margin. | Select only if board space or cost constraints outweigh voltage headroom needs. |
| MJD44H11RLG | TO-220 package, IC = –8A, VCE(sat) = –1.5V @ –4A - higher current but significantly higher conduction loss and larger footprint. | Requires heatsink for >2A operation; incompatible with SOT89 land pattern; suited for legacy through-hole or high-power discrete designs. | Choose only when thermal mass or mechanical mounting dictates TO-220, not for SMT scalability or low-loss optimization. |
Compared with ZXTP2012ZTA and MJD44H11RLG, ZXTP19060CZTA uniquely balances 60V blocking, sub-100mV saturation, and SOT89 thermal performance - making it optimal for space-constrained, high-efficiency 24–48V industrial switching where both voltage margin and conduction loss matter.

FAQ
What is the maximum safe operating temperature for ZXTP19060CZTA?
The device supports junction temperatures from –55°C to +150°C. At TA = +25°C with 50mm × 50mm 2oz copper, RθJA = 51°C/W allows ~47W theoretical dissipation before reaching TJ(max), but derated PD = 2.4W reflects practical limits under standard test conditions and real-world layout constraints.
Can ZXTP19060CZTA replace a MOSFET in high-side switching?
Yes - as a saturated PNP switch, it avoids gate-drive complexity and shoot-through risk of N-channel high-side MOSFETs. However, its fixed VCE(sat) and base current requirement differ from MOSFET RDS(on) and voltage-controlled operation; design must account for hFE-dependent base drive and thermal feedback behavior.
Is ZXTP19060CZTA qualified to AEC-Q101?
No - the datasheet states that AEC-Q101 qualification requires specific change control and PPAP capability; this part is not pre-qualified. Customers needing automotive-grade assurance must contact Diodes Incorporated directly to initiate qualification for their program.
How does the SOT89 package affect thermal performance compared to SOT23?
SOT89's exposed collector pad and larger copper interface provide RθJL = 4.7°C/W - over 5× better than typical SOT23 RθJA. This enables 2–3× higher continuous power handling (2.4W vs. ~0.3–0.5W) with identical PCB area, making it viable for medium-power switching where SOT23 would thermally saturate.
