Product details
Overview
ZUMT717TC from Diodes Incorporated is a PNP bipolar junction transistor designed for high-reliability power switching in compact portable electronics. It delivers -1.25A continuous collector current, -12V VCEO, < -215mV VCE(sat) at -1A, 150mΩ equivalent on-resistance, and meets AEC-Q101 qualification-used in supply line switching for mobile phones and negative boost stages in DC-DC converters.
For engineers reviewing the ZUMT717TC datasheet, ZUMT717TC pinout, ZUMT717TC application, or ZUMT717TC equivalent, key selection criteria include verified VCE(sat) performance at -1.25A, thermal derating on 25mm×25mm PCB, hFE stability up to -3A, and SOT323 package compatibility with high-density layout constraints.
Technical Context
This PNP transistor operates as a low-side switch in negative-rail configurations, supporting fast switching with 50ns turn-on and 135ns turn-off times under -1A load. Its hFE ranges from 300 (at -10mA) to 30 (at -3A), enabling predictable base drive design across operating currents.
The device uses epitaxial planar construction with fully lead-free, halogen- and antimony-free "Green" molding compound (UL 94V-0), rated for -55°C to +150°C operation and qualified per AEC-Q101 for automotive-grade reliability in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -12 V - Maximum allowable collector-emitter voltage before breakdown in common-emitter configuration |
| IC (continuous) | -1.25 A - Continuous safe DC collector current with derated power dissipation above 25°C ambient |
| VCE(sat) | < -215 mV @ IC = -1A, IB = -50mA - Ensures minimal conduction loss and heat generation in switching mode |
| RCE(SAT) | 150 mΩ - Equivalent on-resistance derived from VCE(sat)/IC, critical for thermal management in high-current paths |
| hFE | 300–490 @ IC = -10mA - High DC current gain enables low base drive current, reducing control circuit loading |
| fT | 220 MHz - Current gain-bandwidth product confirming suitability for medium-speed switching (≤1MHz) without oscillation risk |
| PD | 500 mW - Maximum steady-state power dissipation on 25mm×25mm 1oz copper PCB, defining heatsinking requirements |
Pinout & Package
Package: SOT323 - Surface-mount plastic case measuring 2.10 mm × 1.30 mm × 0.95 mm (L × W × H), moisture sensitivity level 1 (J-STD-020), matte tin-plated leads solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal | Connected to higher potential rail (e.g., battery negative or regulated -V); must handle full load current and reverse-bias leakage |
| 2 (Base) | Control input | Receives negative bias current to saturate transistor; requires current-limiting resistor to ensure IB ≤ -100mA peak |
| 3 (Collector) | Current sink terminal | Connected to load return path; low RCE(SAT) minimizes voltage drop during conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including temperature cycling, humidity, and mechanical shock per JESD47 |
| Low VCE(sat) | < -215 mV at -1A ensures ≤215mW conduction loss, reducing thermal stress in space-constrained layouts |
| High hFE consistency | Min 300 at -10mA and 125 at -1.25A supports stable base drive design across full current range |
| Green packaging | Halogen- and antimony-free compound (<900ppm Br/Cl, <1000ppm Sb) compliant with RoHS 2 and JEDEC MSL Level 1 |
| Fast switching | 50ns ton/135ns toff enables efficient operation in DC-DC converters up to 500kHz switching frequency |
Applications
| Mobile Phone Supply Switching | Negative Boost Converter Stage |
|---|---|

IC Role / Device Role / Timing Role: PNP power switch controlling current flow from battery negative to load ground return path. Use Value: Low 150mΩ RCE(SAT) limits voltage drop to <150mV at 1A, preserving system efficiency and minimizing self-heating in thin-profile PCBs. | Use Scenario: Implementing inverted buck-boost topology to generate negative output voltages from positive input in portable audio devices. IC Role / Device Role / Timing Role: Synchronous rectifier or main switching element handling bidirectional current during inductor discharge phase. Use Value: 220MHz fT and sub-200ns switching times support stable regulation at 300–500kHz, reducing output ripple and filter size. |

Use Scenario: Driving small DC motors (e.g., lens focus, tape transport) in ultra-compact camcorders with tight thermal budgets. IC Role / Device Role / Timing Role: Low-side driver in H-bridge half-bridge configuration, sinking motor current during active braking. Use Value: -3A ICM peak rating accommodates motor startup surges without saturation collapse, ensuring reliable stall recovery. | Use Scenario: Managing battery backup switching and low-power subsystem enablement in legacy pagers with strict size and leakage constraints. IC Role / Device Role / Timing Role: Load switch isolating non-critical circuits during sleep mode to reduce quiescent current. Use Value: < -10nA ICES cutoff current prevents battery drain over weeks of standby, extending operational lifetime. |
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 |
|---|---|---|---|
| DXT717PSQ-13 | SOT363 package (dual), lower hFE (min 100), same VCEO/IC ratings | Requires dual-device layout; better suited for matched-pair biasing or complementary switching | Select when dual-channel integration or footprint consolidation outweighs single-device thermal optimization |
| MMDT717-7-F | SOT363 package, slightly higher VCE(sat) (-250mV @ -1A), RoHS-compliant but not AEC-Q101 qualified | Limited to industrial/consumer use; unsuitable for automotive temperature or reliability requirements | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with DXT717PSQ-13 and MMDT717-7-F, ZUMT717TC offers superior single-device thermal performance in SOT323, guaranteed AEC-Q101 compliance, and tighter VCE(sat) specification-making it optimal for space-constrained automotive and portable power switching where reliability and efficiency are co-prioritized.

FAQ
What is the maximum safe operating temperature for ZUMT717TC?
The ZUMT717TC is rated for junction temperatures from -55°C to +150°C. Its thermal resistance (RθJA) is 250°C/W on a 25mm×25mm 1oz copper PCB, meaning at 500mW dissipation, junction temperature rise is 125°C above ambient-so maximum ambient must be ≤25°C for full-rated operation. Derating is required above that point.
Can ZUMT717TC replace a generic PNP transistor like BC807 in automotive designs?
No-ZUMT717TC is AEC-Q101 qualified with verified performance across temperature, humidity, and mechanical stress tests; BC807 lacks this qualification and has higher VCE(sat) (-300mV typical at -500mA). Substitution requires revalidation of thermal, switching, and reliability behavior in the target automotive application.
How does the SOT323 package affect PCB layout for high-current switching?
The SOT323's 0.95mm height and 2.10mm × 1.30mm footprint demand careful copper pour design: the collector pad must connect to ≥25mm² of 1oz copper for 500mW dissipation, and thermal vias under the emitter pad improve heat transfer. Trace widths for -1.25A should exceed 0.5mm to limit resistive heating.
Is ZUMT717TC pin-compatible with its complementary NPN counterpart ZUMT617?
Yes-both use identical SOT323 packages with mirrored pinouts: ZUMT717TC has E-B-C (1-2-3), while ZUMT617 has C-B-E (1-2-3), enabling direct placement in complementary pair circuits without layout revision. This simplifies dual-rail or push-pull designs in DC-DC controllers and motor drivers.
