Product details
Overview
FCX596TA from Diodes Incorporated is a 200V PNP silicon planar high-voltage transistor in SOT89 package, rated for -0.3A continuous collector current, -200V VCEO, and VCE(sat) ≤ -200mV at -0.1A. It serves as a high-voltage switching or linear amplification device in automotive power management, industrial relay drivers, and off-line SMPS bias supplies.
For engineers reviewing the FCX596TA datasheet, FCX596TA pinout, FCX596TA application, or FCX596TA equivalent, key selection criteria include its -200V breakdown rating, low saturation voltage under medium-current drive, thermal performance on FR4 PCBs, and AEC-Q101 qualification readiness for automotive-grade designs.
Technical Context
This PNP bipolar junction transistor operates with emitter-common configuration and supports high-voltage DC switching up to -200V. Its fT of 150MHz enables stable operation in moderate-frequency switching applications, while hFE ranging from 100 (IC = -1mA) to 300 (IC = -1mA) ensures reliable base-driven gain control across load conditions.
Designed for surface-mount use on 15mm × 15mm × 0.6mm FR4 PCBs with single-sided 1oz copper, it delivers 1W power dissipation in still air. The device meets J-STD-020 moisture sensitivity Level 1 and features matte tin-plated leads compliant with MIL-STD-202 Method 208 solderability requirements.
Key Specifications

| IC (cont.) | -0.3A - Continuous collector current limit defining safe DC conduction capability |
| VCE(sat) | -0.2V @ -0.1A/ -0.35V @ -0.25A - Low on-state loss enabling efficient switching in high-side driver topologies |
| hFE | 100–300 - DC current gain range supporting predictable base current sizing across operating currents |
| fT | 150MHz - Transition frequency confirming usable bandwidth for <10MHz switching or analog amplification |

IC Role / Device Role / Timing Role: Medium-power discrete switch interfacing microcontroller GPIO to external load with galvanic isolation. Use Value: 1W thermal rating sustains continuous 0.25A load current on standard PCB; hFE ≥100 ensures robust drive margin over temperature. |

Use Value: Tight hFE spread (100–300) enables accurate current mirroring; fT >150MHz supports fast dimming response to PWM signals. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZTX653 | VCEO = -150V; hFE = 100–250; SOT89 package | Limited to ≤150V systems; lower voltage headroom for transient suppression | Select when cost sensitivity outweighs need for 200V margin and system transients are clamped externally |
| MJD2955T4G | VCEO = -60V; IC = -10A; TO-220 package | Higher current but much lower voltage rating; incompatible with >60V rails | Choose only for high-current, low-voltage linear regulation where thermal mass justifies through-hole mounting |
Compared with ZTX653 and MJD2955T4G, FCX596TA uniquely balances -200V capability, SOT89 compactness, and sub-0.35V saturation in a RoHS-compliant, automotive-ready package-making it optimal for space-constrained, high-reliability 12–48V industrial and automotive switching.

FAQ
Is FCX596TA qualified to AEC-Q101?
No, FCX596TA is not formally AEC-Q101 qualified, but it is manufactured in IATF 16949-certified facilities and supports PPAP documentation. Customers requiring full qualification should contact Diodes directly to initiate the AEC-Q101 stress test program for this part number.
What is the maximum safe operating area (SOA) for FCX596TA?
The FCX596TA SOA is defined by its -200V VCEO, -0.3A IC, and 1W PD limits. At VCE = -100V, maximum continuous IC is ~100mA; at VCE = -200V, IC must be limited to <1mA to avoid secondary breakdown per the datasheet's SOA curve.
Can FCX596TA replace BC807-40 in a 24V circuit?
Only if the circuit operates below 45V and does not require >-0.15A continuous current. BC807-40 has VCEO = -45V and IC = -0.5A; FCX596TA offers higher voltage rating but lower current capacity and different hFE profile-PCB layout and base drive must be re-verified.
Does FCX596TA have built-in ESD protection?
No, FCX596TA does not integrate ESD protection diodes. Its absolute maximum rating for VEB is -5V, making it susceptible to damage from static discharge. External series resistors and TVS clamping on base and emitter lines are recommended in handling and end-equipment design.
