Product details
Overview
ZUMT718TA from Diodes Incorporated is a 20V PNP power switching transistor in SOT323 package, rated for -1A continuous collector current, -20V VCEO, and 500mW power dissipation. It delivers low saturation voltage (−250mV max @ IC = −1A) and on-resistance (200mΩ @ 1A), enabling efficient high-side load switching in automotive body control modules.
For engineers reviewing the ZUMT718TA datasheet, ZUMT718TA pinout, ZUMT718TA application, or ZUMT718TA equivalent, key selection criteria include its AEC-Q101 qualification, −20V breakdown rating, thermal resistance (250°C/W on 25mm² copper), and complementary pairing with ZUMT618 for H-bridge designs.
Technical Context
This PNP bipolar junction transistor operates as a high-side switch with fixed gain characteristics optimized for DC and pulsed load control. Its hFE ranges from 490 (IC = −10mA) down to 75 (IC = −1.5A), supporting stable biasing across wide current loads.
Designed for automotive-grade reliability, it features 4kV HBM ESD tolerance, −55°C to +150°C operating range, and JEDEC-compliant thermal metrics under defined PCB copper layouts-enabling direct integration into space-constrained, thermally demanding modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −20V: Maximum safe collector-emitter reverse bias before avalanche conduction. |
| IC (cont) | −1A: Continuous DC load current capability without derating at TA = 25°C on 25mm² copper. |
| VCE(SAT) | −250mV max @ IC = −1A, IB = −100mA: Low conduction loss enabling <125mW switch dissipation. |
| RCE(SAT) | 200mΩ @ 1A: Equivalent on-resistance directly usable in power loss calculations. |
| fT | 210MHz: Sufficient bandwidth for fast PWM switching up to ~10MHz duty-cycle transitions. |
| ESD HBM | 4000V: Robust handling during board assembly and in-vehicle ESD events per JESD22-A114. |
| TJ Range | −55°C to +150°C: Validated operation across full automotive under-hood temperature envelope. |
Pinout & Package
Package: SOT323 - ultra-small surface-mount plastic case (2.10 × 1.30 × 0.90 mm), matte tin-plated leads, moisture sensitivity level 1, UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal | Connected to supply rail; must handle full load current and withstand VEB ≤ −7V. |
| 2 (Base) | Control input | Receives negative drive current (−100mA typical for full saturation); requires series resistor for current limiting. |
| 3 (Collector) | Switched output | Connected to load; voltage swing limited to −20V; thermal path routed via collector lead to PCB copper. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, lighting, and body electronics per stress test requirements. |
| Low VCE(SAT) | −250mV max ensures <0.25W conduction loss at 1A, reducing thermal burden in sealed modules. |
| Complementary NPN pair | ZUMT618 shares identical SOT323 footprint and matching gain/speed specs for balanced H-bridge implementation. |
| Green construction | Halogen- and antimony-free, RoHS-compliant molding compound and plating meet global environmental compliance mandates. |
| High hFE linearity | hFE ≥ 300 at 10mA enables stable small-signal biasing; retains hFE ≥ 75 up to 1.5A for predictable large-signal drive. |
Applications
| Automotive LED Headlamp Control | Industrial PLC Output Stage |
|---|---|
Use Scenario: Switching 12V/0.8A LED arrays in adaptive front-lighting systems with PWM dimming. IC Role / Device Role / Timing Role: High-side PNP switch controlling current flow from battery to LED cathode return path.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP power switching transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DXT718PSQ-13 | Same SOT323 package, −20V VCEO, but higher VCE(SAT) (−350mV @ −1A) and lower hFE (min 100). | Less suitable for thermally constrained designs; acceptable where cost is prioritized over efficiency. | Select when BOM cost reduction outweighs thermal margin requirements. |
| MMDT718-7-F | SOT363 dual-package variant; single device matches ZUMT718TA specs but shares die with NPN complement in same footprint. | Enables compact dual-switch layouts but requires layout revision for pin compatibility. | Choose for space-constrained dual-channel designs where shared footprint simplifies routing. |
Compared with DXT718PSQ-13 and MMDT718-7-F, ZUMT718TA offers superior saturation performance and AEC-Q101 validation-making it optimal for automotive and industrial applications demanding both reliability and low conduction loss.

FAQ
What is the maximum allowable base current for ZUMT718TA?
The absolute maximum base current is −200mA per the Absolute Maximum Ratings table. For reliable saturation at IC = −1A, the recommended base drive is −100mA, corresponding to hFE ≈ 10. Exceeding −200mA risks permanent bond-wire damage or thermal runaway under sustained conditions.
Can ZUMT718TA be used in parallel configurations?
No-ZUMT718TA lacks built-in emitter ballasting or matched gain characteristics required for safe current sharing. Parallel use may cause thermal imbalance and premature failure due to hFE variation (±20% typical). For higher current, select a single higher-rated device or implement external current-sharing resistors.
Is ZUMT718TA compatible with lead-free reflow profiles?
Yes-ZUMT718TA uses matte tin-plated leads and green molding compound qualified for standard lead-free reflow (J-STD-020 Level 1). Peak temperature tolerance is 260°C for 30 seconds; thermal resistance values assume proper solder joint formation on 1oz copper pads per AP02001 layout guidelines.
How does the 250°C/W RθJA value translate to real-world PCB design?
The 250°C/W rating applies only when the collector lead is soldered to a 25mm × 25mm 1oz copper area. On typical 10mm × 8mm copper, RθJA degrades to 325°C/W. To achieve rated thermal performance, ensure ≥625mm² copper pour connected directly to the collector pad with multiple thermal vias to inner layers.
