Product details
Overview
ZTX753STOA from Diodes Incorporated is a PNP silicon planar medium-power bipolar junction transistor (BJT) designed for linear amplification and switching in industrial power control circuits. It delivers -100 V VCEO, -2 A continuous collector current, and low saturation voltage (VCE(sat) = -0.3 V at IC = -2 A, IB = -200 mA), enabling efficient operation in DC-DC converters and relay drivers.
For engineers reviewing the ZTX753STOA datasheet, ZTX753STOA pinout, ZTX753STOA application, or ZTX753STOA equivalent, key selection criteria include verified PNP polarity, TO-92-compatible package thermal resistance (Rth(j-amb) = 116 °C/W on PCB), and guaranteed fT ≥ 100 MHz under pulsed conditions - critical for high-speed switching and analog gain stability.
Technical Context
This BJT operates with fixed-current gain (hFE) ranging from 75 to 225 at IC = -1 A and VCE = -2 V, supporting predictable biasing in Class-A amplifiers and saturated-switch configurations. Its breakdown ratings - V(BR)CBO = -120 V, V(BR)CEO = -100 V, and V(BR)EBO = -5 V - define safe operating limits in negative-rail power stages.
Thermal performance is characterized by Rth(j-case) = 70 °C/W and Rth(j-amb) = 116 °C/W (on 1 in² copper PCB), allowing sustained 1 W dissipation at Tamb ≤ 25°C with linear derating. Switching behavior includes ton = 40 ns and toff = 600 ns at IC = -500 mA, VCC = -10 V, confirming suitability for <100 kHz hard-switched topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -100 V - Maximum allowable collector-emitter voltage before avalanche in common-emitter configuration |
| IC (cont.) | -2 A - Continuous DC collector current rating defining maximum linear/saturated load drive capability |
| VCE(sat) | -0.3 V (max) at IC = -2 A, IB = -200 mA - Low conduction loss enabling >95% efficiency in high-side switch applications |
| fT | 100 MHz (min) at IC = -100 mA, VCE = -5 V - Minimum transition frequency ensuring stable small-signal gain up to audio and low-RF bands |
| Rth(j-amb) | 116 °C/W on 1 in² PCB - Thermal resistance used to calculate junction temperature rise under real PCB layout conditions |
| toff | 600 ns - Measured turn-off delay limiting usable switching frequency in pulse-width modulated power stages |
Pinout & Package
Package: TO-92 compatible (3-lead plastic case, E-line marking). Standard lead configuration with emitter (E), base (B), and collector (C) arranged in linear order when viewed with flat side facing user and leads downward.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| E (Emitter) | Current sink terminal in PNP topology | Connected to most positive rail in high-side switch; sets reference for base bias and current flow direction |
| B (Base) | Control input for minority-carrier injection | Requires negative current relative to emitter to forward-bias BE junction and enable conduction |
| C (Collector) | Main output current path | Connected to load; voltage swing limited by V(BR)CEO = -100 V and safe operating area curves |
Key Features
| Feature | Design Value |
|---|---|
| High VCEO rating | -100 V enables use in 48 V and 72 V industrial bus systems without series stacking |
| Low VCE(sat) | -0.3 V max reduces conduction losses by >40% vs. standard PNP transistors at 2 A load |
| Guaranteed fT | ≥100 MHz ensures stable small-signal amplification up to 20 kHz with margin for layout parasitics |
| Robust thermal design | Rth(j-amb) = 116 °C/W on standard PCB allows 1 W operation without forced air or heatsink |
Applications
| DC-DC Converter High-Side Switch | Industrial Relay Driver |
|---|---|
Use Scenario: Controlling 24–48 V DC loads in programmable logic controller (PLC) output modules. IC Role / Device Role / Timing Role: PNP BJT configured as saturated switch, driven by microcontroller GPIO through current-limiting resistor. Use Value: VCE(sat) ≤ -0.3 V minimizes power loss during sustained ON state, reducing thermal stress on PCB traces. | Use Scenario: Driving 12–24 V coil relays in factory automation I/O cards. IC Role / Device Role / Timing Role: Medium-power switching element providing galvanic isolation between logic and inductive load. Use Value: 600 ns toff ensures clean deactivation of relay coil without contact arcing or back-EMF-induced latch-up. |
| Analog Signal Amplifier | Linear Voltage Regulator Pass Element |
Use Scenario: Low-noise preamplifier stage in sensor signal conditioning for pressure transducers. IC Role / Device Role / Timing Role: Common-emitter amplifier biased at IC = -1 mA with hFE = 175 typical for stable gain. Use Value: fT ≥ 100 MHz provides bandwidth headroom beyond 20 kHz audio range, preserving transient fidelity. | Use Scenario: Series pass transistor in adjustable 3–15 V linear regulators for test equipment power supplies. IC Role / Device Role / Timing Role: Continuously conducting PNP element dissipating up to 1 W while regulating output voltage. Use Value: Rth(j-amb) = 116 °C/W permits full-rated power dissipation on standard FR-4 with 1 in² copper pour, eliminating need for external heatsink. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD2955G | VCEO = -70 V, IC = -12 A, TO-220 package, higher Ptot = 115 W | Requires heatsink; unsuitable for space-constrained TO-92 footprints | Select when higher current and thermal capacity are needed, not for direct footprint replacement |
| ZTX751STOA | VCEO = -80 V, VCE(sat) = -0.5 V (max) at same IC/IB, otherwise identical package and pinout | Lower breakdown and higher saturation loss reduce efficiency in 48 V systems | Use only where lower voltage rails (<40 V) and relaxed thermal budgets apply |
Compared with MJD2955G and ZTX751STOA, ZTX753STOA uniquely balances -100 V rating, TO-92 compatibility, and sub-0.3 V saturation in a single device - making it optimal for compact, medium-voltage industrial controls where board space and thermal management are constrained.

FAQ
Is ZTX753STOA RoHS compliant and halogen-free?
Yes, ZTX753STOA meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21. The TO-92 package uses lead-free matte tin plating and compliant molding compound, with full material declarations available upon request for automotive and medical-grade audits.
What is the maximum safe operating temperature for continuous operation?
The junction temperature must not exceed +200°C, and ambient temperature must stay within -55°C to +150°C for rated performance. At 25°C ambient, full 1 W dissipation is allowed; above that, linear derating applies at 5.7 mW/°C - meaning 0.5 W max at +110°C ambient on standard PCB.
Can ZTX753STOA replace ZTX752STOA in existing designs?
Yes, ZTX753STOA is a direct upgrade: it shares identical TO-92 package, pinout, and biasing requirements, but offers improved VCEO (-100 V vs. -80 V) and lower VCE(sat) (-0.3 V vs. -0.5 V), enhancing reliability in 48 V systems without layout changes.
Does ZTX753STOA require a base resistor in switching applications?
Yes - a series base resistor is mandatory to limit IB and ensure saturation. For IC = -2 A with hFE ≥ 75, minimum IB = -26.7 mA is required; using 5 V logic drive, a 150 Ω resistor delivers -33 mA, guaranteeing hard saturation and minimizing VCE(sat).
