Product details
Overview
DSS5160FDB-7 from Diodes Incorporated is a dual PNP low-VCE(sat) transistor in a U-DFN2020-6 package, rated for -60V VCEO, -1A continuous collector current per channel, and 200mΩ equivalent on-resistance. It serves as a compact, high-efficiency load switch in power management circuits, charging systems, and motor/fan drive stages where space-constrained, thermally efficient switching is required.
For engineers reviewing the DSS5160FDB-7 datasheet, DSS5160FDB-7 pinout, DSS5160FDB-7 application, or DSS5160FDB-7 equivalent, key selection criteria include its dual-channel PNP topology, -340mV VCE(sat) at -1A/-100mA, 0.6mm profile, RθJA as low as 51°C/W with enhanced copper layout, and RoHS-compliant "Green" construction.
Technical Context
This dual PNP transistor integrates two matched silicon die in a single U-DFN2020-6 leadless package with exposed collector pads for thermal performance. Each channel supports independent operation with BVCEO = -60V, VCE(sat) ≤ -340mV @ -1A/-100mA, and hFE ≥ 70 at -1A.
The device uses NiPdAu-plated terminals for solderability and achieves RθJL = 18°C/W to the exposed collector leads. Its transient thermal impedance and safe operating area (SOA) are characterized for pulsed and DC load-switching duty cycles up to 150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -60V - Supports robust blocking in negative-rail power switches up to industrial 48V systems. |
| IC (cont.) | -1A per channel - Enables direct control of moderate-power loads like fans, LEDs, or charging paths without external drivers. |
| VCE(sat) | -340mV @ -1A/-100mA - Minimizes conduction loss and self-heating in high-duty-cycle load switching. |
| RCE(sat) | 200mΩ - Equivalent on-resistance enables predictable voltage drop modeling in power path analysis. |
| RθJA | 51°C/W (with 28mm × 28mm 2oz Cu) - Delivers 2.47W max power dissipation in optimized PCB layouts. |
| Package | U-DFN2020-6 - 2.0 × 2.0 × 0.6mm footprint ideal for ultra-thin portable and wearable electronics. |
| ESD HBM | 4000V - Provides inherent system-level ESD resilience in end-equipment without added protection circuitry. |
Pinout & Package
U-DFN2020-6 is a 6-terminal, bottom-exposed, leadless plastic package with dual exposed collector pads (C1, C2) for thermal and electrical connection. Pin 1 identifier is marked by a chamfered corner (bottom view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (C1) | Collector 1 | Exposed pad - primary thermal path and high-current output node for Q1. |
| 2 (B1) | Base 1 | Control input for Q1; requires current-limited drive due to VBE(sat) ≈ -1.0V @ -1A. |
| 3 (E1) | Emitter 1 | High-side reference node for Q1; connects to supply rail in high-side switch configuration. |
| 4 (E2) | Emitter 2 | High-side reference node for Q2; electrically isolated from E1 but same potential in dual-switch applications. |
| 5 (B2) | Base 2 | Independent control input for Q2; enables synchronous or staggered dual-load switching. |
| 6 (C2) | Collector 2 | Exposed pad - primary thermal path and high-current output node for Q2. |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP topology | Two matched, independently controllable transistors reduce board area vs. discrete solutions and simplify dual-load routing. |
| Low-profile 0.6mm height | Enables integration into <1.0mm-thick consumer devices such as smartwatches and hearing aids. |
| RθJA 40% lower than SOT-26 | Improves thermal headroom in dense layouts without heatsinks or airflow - critical for sealed enclosures. |
| Halogen & antimony free | Meets IEC 61249-2-21 and JEDEC J-STD-70B for environmentally compliant manufacturing and disposal. |
| NiPdAu terminal finish | Ensures reliable solder joint formation and long-term intermetallic stability under thermal cycling. |
Applications
| USB-C Power Delivery Switching | Wireless Charging Control |
|---|---|
Use Scenario: Managing bidirectional 5–20V power path selection between source and sink in USB-C PD controllers. IC Role / Device Role: Dual high-side PNP switch enabling independent enable/disable of VBUS and VCONN rails. Use Value: -340mV VCE(sat) minimizes voltage droop across 1A charging currents, preserving PD negotiation margins. |
Use Scenario: Enabling/disabling transmitter coil power and receiver rectifier bias in Qi-compliant charging modules. IC Role / Device Role: Load switch controlling gate drive and bias supplies to GaN FETs and synchronous rectifiers. Use Value: 0.6mm profile allows placement beneath thin ferrite shields; dual channels support Tx/Rx isolation without cross-talk. |
| Industrial Sensor Node Power Gating | Medical Wearable Battery Management |
Use Scenario: Selectively powering analog front-end ICs (e.g., ADCs, amplifiers) in battery-operated IIoT sensors during measurement cycles. IC Role / Device Role: Low-leakage, high-VCEO switch isolating sub-circuits to extend shelf life and reduce quiescent current. Use Value: -100nA ICBO at -48V ensures <1µA total leakage per channel, critical for multi-year battery life. |
Use Scenario: Isolating rechargeable Li-ion battery from patient-monitoring subsystems (ECG, SpO₂) during sleep mode. IC Role / Device Role: Dual-channel power gate managing separate analog and digital domain supplies to meet IEC 62304 safety requirements. Use Value: Matched hFE and VCE(sat) ensure balanced turn-on timing and thermal distribution across safety-critical domains. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3026LSD-13 | N-channel dual MOSFET (30V, 3.2A), logic-level gate, no body diode conduction in reverse direction. | Requires level-shifting for high-side use; better for low-VDS(on) (<20mΩ) but lacks native high-side simplicity. | Select when efficiency at <100mA matters more than board space or gate drive complexity. |
| ZXTDM617000CTA | Dual PNP (60V, -1.5A), SOT-26 package, higher RθJA (125°C/W), no exposed thermal pad. | Larger footprint (3.0 × 1.7mm), less suitable for ultra-thin designs; lower thermal performance limits sustained 1A operation. | Choose only if legacy SMT process cannot accommodate U-DFN2020-6 reflow profiles or stencil design. |
Compared with DMN3026LSD-13 and ZXTDM617000CTA, DSS5160FDB-7 uniquely combines dual PNP functionality, 0.6mm height, and 51°C/W thermal resistance - making it optimal for space- and thermally constrained high-side switching where gate drive simplicity and SOA margin are prioritized over sub-50mΩ on-resistance.

FAQ
What is the maximum continuous current per channel for DSS5160FDB-7?
The DSS5160FDB-7 supports -1A continuous collector current per channel at TA = +25°C with recommended PCB copper area (28mm × 28mm, 2oz). Derating applies above 25°C ambient; at 85°C, max IC drops to approximately -0.65A per channel based on the published derating curve.
Can DSS5160FDB-7 be used in high-side switch configurations?
Yes - its dual PNP structure is inherently suited for high-side switching. Emitters connect to positive supply rails; collectors drive loads to ground. Base drive must be referenced to emitter potential, typically using resistor-limited current sources or dedicated PNP driver ICs to ensure sufficient -100mA base current for full saturation at -1A load.
Is the U-DFN2020-6 package compatible with standard reflow profiles?
Yes - the U-DFN2020-6 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity Level 1 and supports standard lead-free reflow profiles (peak 260°C, 60s max above 217°C). The NiPdAu terminal finish ensures wetting reliability; recommended stencil aperture is 100% opening with 0.1mm thickness for optimal solder paste release.
Does DSS5160FDB-7 have integrated ESD protection?
Yes - it meets JEDEC JESD22-A114 Class 3A (4000V HBM) and JESD22-A115 (400V MM) ESD ratings. This level of on-die protection eliminates need for external TVS diodes in most consumer and industrial interfaces, though system-level ESD testing remains essential for final product validation.
