Product details
Overview
1PS59SB14,115 from Nexperia is a dual Schottky barrier diode in SC59 SMD package, featuring 30 V reverse voltage rating, 200 mA continuous forward current per diode, and ultra-fast 5 ns reverse recovery time. It serves as a clamping or protection device in high-speed DC-DC converter feedback paths and USB port ESD protection circuits.
For engineers reviewing the 1PS59SB14,115 datasheet, 1PS59SB14,115 pinout, 1PS59SB14,115 application, or 1PS59SB14,115 equivalent, key selection criteria include its dual-common-cathode configuration, low 400 mV forward voltage at 10 mA, 2 µA reverse leakage at 25 V, and thermal resistance of 500 K/W - all critical for compact power rail protection designs.
Technical Context
The 1PS59SB14,115 integrates two independent Schottky diodes sharing a common cathode (Pin 2), with anode terminals on Pins 1 and 3. Its planar construction and guard ring protection ensure stable reverse breakdown behavior and reliability under transient stress.
This dual-diode topology enables bidirectional clamping across a shared reference node, supporting voltage limiting in both polarities while maintaining low conduction loss - essential for 3.3 V/5 V bus protection and synchronous rectifier auxiliary paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 30 V - supports clamping up to 30 V DC rails without breakdown |
| IF (Continuous Forward Current) | 200 mA per diode - sufficient for low-power signal-level protection and biasing |
| VF (Forward Voltage) | 400 mV at 10 mA - minimizes power loss and self-heating in always-on protection paths |
| trr (Reverse Recovery Time) | 5 ns - enables operation in >100 MHz switching environments without tail current issues |
| IR (Reverse Current) | 2 µA at 25 V - ensures negligible leakage in high-impedance sensing or reference nodes |
| Cd (Diode Capacitance) | 10 pF at 1 V VR - preserves signal integrity in RF-adjacent or high-speed data line protection |
| Rth j-a | 500 K/W - requires minimal PCB copper area for thermal management in space-constrained layouts |
Pinout & Package
Package: SC59 - surface-mount plastic package measuring 2.7 mm × 1.3 mm × 1.0 mm (L × W × H), optimized for automated placement and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input terminal for first Schottky path; connects to protected signal or supply rail |
| Pin 2 | Common Cathode | Shared output node; ties both diodes to ground or reference potential |
| Pin 3 | Anode of Diode 2 | Input terminal for second Schottky path; enables dual-rail or differential clamping |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Prevents edge breakdown and improves long-term reliability under repetitive surge stress |
| Low VF at low IF | 240 mV at 0.1 mA enables effective clamping even in micro-power monitoring circuits |
| Dual-anode / common-cathode topology | Supports symmetrical bidirectional clamping without external component duplication |
| SC59 footprint compatibility | Matches JEDEC MO-203AA standard - enables drop-in replacement in existing layouts |
Applications
| USB 2.0 Data Line Protection | DC-DC Converter Feedback Clamp |
|---|---|
Use Scenario: Protecting D+ and D− lines against ESD transients and overvoltage during hot-plug events. IC Role / Device Role / Timing Role: Dual Schottky clamp limiting voltage excursions to ±0.3 V beyond VDD/VSS rails. Use Value: 5 ns trr prevents signal distortion at 480 Mbps; 10 pF capacitance avoids USB eye diagram degradation. | Use Scenario: Clamping op-amp output in isolated flyback feedback loops to prevent saturation during load transients. IC Role / Device Role / Timing Role: Fast-recovery dual diode routing error amplifier output to optocoupler input. Use Value: 400 mV VF ensures precise regulation threshold; common-cathode layout simplifies PCB routing. |
| Low-Voltage Logic Level Shifting | Industrial Sensor Signal Conditioning |
Use Scenario: Bidirectional level translation between 1.8 V I²C master and 3.3 V sensor slave. IC Role / Device Role / Timing Role: Passive clamping diode pair establishing safe voltage windows on SDA/SCL lines. Use Value: 2 µA IR avoids pull-up current loading; 200 mA IF rating handles peak I²C bus contention currents. | Use Scenario: Protecting analog front-end inputs of 24 V industrial sensors against reverse polarity and inductive kickback. IC Role / Device Role / Timing Role: Dual-anode configuration routes fault current from either input polarity to common ground. Use Value: 30 V VR withstands 24 V system surges; guard ring ensures stability in dusty/humid environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G | Single diode in SOD-523; no common-cathode dual configuration | Requires two devices and extra routing for dual-rail clamping | Choose when only one clamping path is needed and board area allows discrete placement |
| BAT54C,215 | Same SC59 package and dual-common-cathode pinout; 30 V VR, but VF = 450 mV @ 10 mA | Higher forward drop increases power loss in always-on protection paths | Acceptable where 50 mV VF penalty is tolerable and legacy BAT54C sourcing is preferred |
Compared with RB520S-30T1G and BAT54C,215, the 1PS59SB14,115 delivers lower forward voltage and guaranteed 5 ns trr in a true dual-common-cathode SC59 package - making it optimal for space-constrained, high-speed bidirectional clamping where thermal and timing margins are tight.

FAQ
What is the pin configuration of the 1PS59SB14,115?
The 1PS59SB14,115 uses a three-pin SC59 package with Pin 1 as Anode 1, Pin 2 as Common Cathode, and Pin 3 as Anode 2. This dual-common-cathode arrangement is confirmed in Figure 3 of the original Philips/Nexperia datasheet and enables symmetrical clamping across a shared reference node. The 1PS59SB14,115 pinout differs from single-diode variants like 1PS59SB10 and other dual configurations such as 1PS59SB15.
Does the 1PS59SB14,115 support bidirectional voltage clamping?
Yes, the 1PS59SB14,115 supports bidirectional clamping via its dual-anode/common-cathode structure: applying positive overvoltage to either anode pulls current through the respective diode to the common cathode, while negative transients are blocked by reverse bias. This makes the 1PS59SB14,115 ideal for protecting differential pairs like USB D+/D− or RS-485 lines without additional components.
What is the maximum junction temperature for the 1PS59SB14,115?
The maximum junction temperature for the 1PS59SB14,115 is 125 °C, as specified in the Limiting Values table of the Nexperia datasheet. This rating assumes operation within the absolute maximum ratings and proper PCB thermal design - the 500 K/W junction-to-ambient thermal resistance means that at 200 mA forward current and 400 mV VF, junction temperature rise is approximately 40 °C above ambient, keeping the 1PS59SB14,115 well within safe operating limits at typical board temperatures.
How does the 1PS59SB14,115 compare to the BAT54C,215 in terms of forward voltage?
The 1PS59SB14,115 has a lower typical forward voltage: 400 mV at 10 mA versus 450 mV for the BAT54C,215. This 50 mV difference reduces conduction loss by ~12.5% at the same current, improving efficiency in always-on protection paths. Both share the SC59 package and dual-common-cathode pinout, so the 1PS59SB14,115 can serve as a direct performance upgrade in existing BAT54C,215 designs where lower VF is critical.
Is the 1PS59SB14,115 suitable for automotive applications?
The 1PS59SB14,115 is not AEC-Q101 qualified and is not recommended for automotive safety-critical systems. While its 125 °C max junction temperature and robust guard ring construction support industrial-grade operation, Nexperia positions this device for consumer, computing, and general industrial use. For automotive applications requiring qualification, engineers should select AEC-Q101-rated alternatives - the 1PS59SB14,115 remains appropriate for non-safety automotive infotainment or accessory modules where qualification is not mandated.
