Product details
Overview
ZXTP5401FLQTA from Diodes Incorporated is a 150V PNP high-voltage bipolar junction transistor (BJT) in SOT23 package, rated for -600mA continuous collector current, -150V VCEO, and AEC-Q101 qualified for automotive power switching. It delivers low VCE(sat) of -70mV at -10mA/-1mA drive and stable hFE up to 240 at -50mA, enabling robust load control in 12V/24V vehicle subsystems.
For engineers reviewing the ZXTP5401FLQTA datasheet, ZXTP5401FLQTA pinout, ZXTP5401FLQTA application, or ZXTP5401FLQTA equivalent, key selection criteria include its -150V breakdown rating, thermal resistance of 357°C/W on 15mm×15mm PCB, complementary pairing with ZXTN5551FLQ, and IATF16949-manufactured traceability for safety-critical automotive designs.
Technical Context
This PNP BJT operates as a high-side switch or linear amplifier in automotive power management, supporting pulsed operation up to 1A peak with <2% duty cycle. Its fT of 100MHz and fast switching times (td = 386ns, ts = 1720ns) enable use in PWM-driven solenoid and relay drivers where voltage headroom and thermal stability are critical.
The device features excellent hFE linearity across -1mA to -50mA (50–240), low VBE(sat) (-750mV max at -50mA), and tight parameter distribution validated under AEC-Q101 stress tests including HTGB, HTRB, and temperature cycling from -55°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -150V - Enables safe operation in 24V automotive systems with transient spikes up to ±100V. |
| IC (continuous) | -600mA - Supports driving medium-power loads like fuel injectors, HVAC actuators, and LED arrays. |
| VCE(sat) | -70mV @ -10mA/-1mA - Minimizes conduction loss and self-heating in high-duty-cycle switching. |
| hFE | 240 @ -50mA - Ensures reliable base drive margin and stable gain in feedback-controlled regulators. |
| RθJA | 357°C/W - Achievable on 15mm×15mm FR4 PCB; enables 310mW dissipation at +85°C ambient. |
| fT | 100MHz - Supports clean switching at PWM frequencies up to ~10MHz with minimal phase lag. |
| TJ range | -55°C to +150°C - Qualified for under-hood engine control module placement without derating. |
Pinout & Package
Package: SOT23 - Surface-mount plastic package (0.008g weight), UL 94V-0 rated, moisture sensitivity level 1, matte tin terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal | Connected to positive rail in high-side switch configuration; must handle full load current and reverse-bias transients. |
| 2 (Base) | Control input | Receives negative drive current to turn on; requires current-limiting resistor to ensure IB ≤ -5mA per spec. |
| 3 (Collector) | Load connection node | Connected to load ground return; carries switched current and dissipates heat via PCB copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use with PPAP capability and IATF16949 manufacturing-required for ASIL-B subsystems. |
| High BVCEO | -150V rating provides 2.5× margin over 48V nominal battery systems, reducing need for external clamping. |
| Low VCE(sat) | -70mV at -10mA ensures <0.7mW conduction loss, minimizing thermal rise in space-constrained modules. |
| Complementary NPN pair | ZXTN5551FLQ shares identical SOT23 footprint and thermal profile, simplifying dual-rail driver board layout. |
| Green construction | Halogen- and antimony-free (<900ppm Br+Cl, <1000ppm Sb), meeting global automotive environmental mandates. |
Applications
| Fuel Injector Driver | Body Control Module Load Switch |
|---|---|
Use Scenario: Driving 12V solenoid-type fuel injectors in port fuel injection systems with PWM modulation up to 2kHz. IC Role / Device Role / Timing Role: High-side PNP switch controlling injector coil current; handles inductive kickback via inherent VCEO margin. Use Value: -150V VCEO withstands >100V flyback spikes without snubber, reducing BOM count and PCB area. | Use Scenario: Controlling door lock actuators, window lift motors, and interior lighting in centralized body control units. IC Role / Device Role / Timing Role: Medium-current load switch interfacing MCU GPIOs to 24V loads; driven by open-drain logic with pull-up. Use Value: Stable hFE across temperature ensures consistent turn-on behavior from -40°C cold cranking to +105°C cabin heat. |
| Engine Coolant Fan Controller | LED Headlamp Dimming Circuit |

IC Role / Device Role / Timing Role: Linear pass element or PWM switch in low-noise fan driver; dissipates up to 250mW during partial-load operation. Use Value: RθJA = 357°C/W allows full 600mA current at +85°C ambient without heatsink-reducing system cost. | Use Scenario: Implementing analog dimming for adaptive front-lighting system (AFS) LEDs using constant-current sink topology. IC Role / Device Role / Timing Role: Precision current regulator in emitter-follower configuration; sets LED current via base voltage reference. Use Value: Tight hFE tolerance (50–240) and low VBE(sat) variation (<300mV) maintain ±3% current accuracy across production lots. |
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 |
|---|---|---|---|
| ZXTP5402FLQTA | Same SOT23 package, but -100V VCEO and -1A IC; higher current, lower voltage rating. | Suitable for 12V-only systems where higher surge current matters more than transient immunity. | Select when load current exceeds 600mA and voltage transients remain below 80V. |
| MMBT5401 | Same die but non-automotive grade: no AEC-Q101, no PPAP, wider parametric spread, not IATF16949 manufactured. | Limited to consumer or industrial applications without functional safety requirements. | Choose only for cost-sensitive non-automotive designs where qualification documentation is unnecessary. |
Compared with ZXTP5401FLQTA, ZXTP5402FLQTA trades voltage headroom for current capacity-ideal for 12V starter relays-while MMBT5401 omits automotive validation entirely, requiring full requalification for any vehicle deployment.

FAQ
What is the maximum allowable base-emitter reverse voltage for ZXTP5401FLQTA?
The absolute maximum VEBO is -5V, with typical breakdown at -8.1V per test condition (IE = -100µA). Exceeding -5V risks permanent damage to the base-emitter junction, especially during hot-plug or ESD events. Designers must limit reverse bias using clamping diodes or resistor networks when interfacing with open-collector drivers.
Can ZXTP5401FLQTA be used in linear regulator applications?
Yes-it supports linear operation with VCE between -0.5V and -100V and maintains hFE stability across -1mA to -50mA. However, power dissipation must stay within 310mW (derated above +25°C), requiring careful thermal design. Its low VCE(sat) and predictable gain make it viable for low-dropout pre-regulators in sensor signal chains.
Is the SOT23 footprint of ZXTP5401FLQTA compatible with standard pick-and-place equipment?
Yes-the SOT23 package conforms to JEDEC MO-178AB standard with 0.95mm pitch, 2.9mm length, and 1.3mm width. Diodes specifies exact pad dimensions (C = 2.0×0.8mm, X1 = 1.35mm) and recommends 7° solder mask expansion. The matte tin finish ensures compatibility with lead-free reflow profiles (peak 260°C).
How does the AEC-Q101 qualification impact the reliability testing of ZXTP5401FLQTA?
AEC-Q101 qualification requires passing 13 stress tests including HTGB (1000h at 150°C), HTRB (1000h at 150°C/VCEO), and temperature cycling (-55°C to +150°C, 1000 cycles). These validate long-term parametric stability and interconnect integrity-critical for 15-year automotive service life. Data sheets list only post-test limits, not raw failure rates.
