Product details
Overview
1PS59SB16,115 from Nexperia is a dual Schottky barrier diode in SC59 package, configured as common-cathode pair with anode terminals on pins 1 and 2, cathode shared on pin 3. It delivers 30 V reverse voltage rating, 200 mA continuous forward current per diode, and ultrafast 5 ns reverse recovery time - enabling use in high-frequency clamping and protection circuits for USB data lines and low-voltage DC-DC converters.
For engineers reviewing the 1PS59SB16,115 datasheet, 1PS59SB16,115 pinout, 1PS59SB16,115 application, or 1PS59SB16,115 equivalent, key selection criteria include its common-cathode dual-diode topology, 5 ns trr, 400 mV VF at 10 mA, 10 pF capacitance at 1 V VR, and SC59 thermal resistance of 500 K/W - all critical for ESD-tolerant signal routing and compact power rail protection.
Technical Context
This dual Schottky diode integrates two planar junctions in a single SC59 SMD package with guard ring protection to suppress edge leakage and improve reliability under transient stress. Its low 240 mV forward voltage at 0.1 mA enables precise low-current biasing in sensing paths.
The device operates up to 125 °C junction temperature and supports repetitive peak forward currents up to 300 mA (tp ≤ 1 s, δ ≤ 0.5), making it suitable for pulsed clamp applications in automotive body control modules and industrial I/O protection where thermal cycling resilience is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - defines maximum allowable DC or steady-state reverse bias before breakdown in clamping or blocking roles. |
| Forward Voltage (VF) | 400 mV at 10 mA - ensures minimal conduction loss in low-voltage signal path protection (e.g., 3.3 V logic rails). |
| Reverse Recovery Time (trr) | 5 ns - enables reliable operation in >100 MHz switching environments such as USB 2.0 data line transient suppression. |
| Diode Capacitance (Cd) | 10 pF at 1 MHz, 1 V VR - limits signal distortion in high-speed digital interfaces without requiring additional series impedance. |
| Junction-to-Ambient Rth | 500 K/W - requires careful PCB copper area design for thermal management in sustained 200 mA operation. |
| Storage Temperature | −65 °C to +150 °C - supports reflow soldering compatibility and extended deployment in under-hood automotive environments. |
Pinout & Package
Package: SC59 - surface-mount plastic package measuring 3.0 × 1.7 × 1.3 mm (L × W × H), with gull-wing leads optimized for automated assembly and thermal performance on standard FR-4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input terminal for first Schottky junction; connects to protected signal or supply rail requiring clamping. |
| 2 | Anode of Diode 2 | Independent input terminal for second junction; enables dual-rail or differential clamping (e.g., D+ and D−). |
| 3 | Common Cathode | Shared output node tied to reference (e.g., GND or VCC); defines common return path for both diodes. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Suppresses surface leakage and improves long-term stability under humidity and bias stress in industrial control interfaces. |
| Low VF at microamp levels | 240 mV at 0.1 mA enables accurate voltage threshold detection in battery-monitoring comparators. |
| Ultra-low trr | 5 ns recovery time prevents false triggering in high-edge-rate digital bus protection (e.g., CAN FD stubs or LVDS lines). |
| SC59 footprint compatibility | Standardized 3-pin gull-wing layout allows drop-in replacement with other SC59 dual diodes without PCB redesign. |
Applications
| USB 2.0 Data Line Protection | Low-Voltage DC-DC Output Clamp |
|---|---|
Use Scenario: Protecting D+ and D− lines against ESD and overvoltage transients in portable USB peripherals. IC Role / Device Role: Dual common-cathode Schottky clamp directing surge current to ground while preserving signal integrity. Use Value: 5 ns trr and 10 pF capacitance prevent data eye closure; 400 mV VF avoids forward-bias interference with 3.3 V signaling. | Use Scenario: Clamping output overshoot during load transients in buck converter outputs (e.g., 1.8 V core rails). IC Role / Device Role: Fast-acting voltage limiter absorbing inductive kickback from synchronous rectifiers. Use Value: 30 V VR withstands typical 12 V input surges; 200 mA IF rating supports sustained clamp duty in 5 A converters. |
| Automotive Body Control I/O Protection | Industrial Sensor Signal Conditioning |
Use Scenario: Safeguarding LIN bus or switch inputs in door module ECUs exposed to load dump and jump-start conditions. IC Role / Device Role: Bidirectional transient suppressor using dual anodes referenced to chassis ground. Use Value: −65 °C to +150 °C Tstg ensures operation across full automotive ambient range; guard ring enhances humidity robustness. | Use Scenario: Level-shifting and overvoltage protection for analog sensor outputs (e.g., thermistor bridges) feeding 3.3 V ADCs. IC Role / Device Role: Precision low-VF clamp limiting excursion beyond supply rails without loading source impedance. Use Value: 240 mV VF at 0.1 mA enables sub-mV threshold accuracy; SC59 size fits dense sensor PCB layouts. |
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 | Higher VF (450 mV @ 10 mA), same 30 V VR and SC59 package; no guard ring. | Lacks guard ring; less stable in humid industrial enclosures. | Acceptable for cost-sensitive consumer USB ports where long-term reliability is secondary. |
| BAT54C,215 | Same common-cathode SC59 pinout; VF = 370 mV @ 10 mA; trr = 4 ns; Cd = 12 pF. | Slightly faster trr but higher capacitance - may degrade >480 Mbps USB signals. | Preferred for ultra-high-speed clamping where 1 ns trr advantage outweighs added 2 pF capacitance. |
Compared with RB520S-30T1G and BAT54C,215, the 1PS59SB16,115 offers superior leakage control via guard ring and optimal VF–trr–Cd balance for USB 2.0 and automotive I/O, while maintaining identical SC59 footprint and thermal behavior.

FAQ
What is the pin configuration of the 1PS59SB16,115?
The 1PS59SB16,115 uses a common-cathode dual-diode configuration in SC59 package: pin 1 is anode of diode 1, pin 2 is anode of diode 2, and pin 3 is the shared cathode. This layout is confirmed in Figure 5 of the original Philips/Nexperia datasheet and matches the MLC360 symbol diagram.
Does the 1PS59SB16,115 have guard ring protection?
Yes, the 1PS59SB16,115 incorporates guard ring protection as explicitly stated in the FEATURES section of the datasheet. This structure reduces surface leakage current and improves long-term reliability under bias stress and humid operating conditions - a distinguishing feature versus non-guarded alternatives like RB520S-30T1G.
What is the maximum junction temperature for the 1PS59SB16,115?
The maximum junction temperature (Tj) for the 1PS59SB16,115 is 125 °C, as specified in the LIMITING VALUES table. This rating applies under continuous operation within absolute maximum ratings and must be verified against actual power dissipation and PCB thermal design using the 500 K/W Rth j-a value.
Can the 1PS59SB16,115 be used in USB 2.0 ESD protection circuits?
Yes, the 1PS59SB16,115 is well-suited for USB 2.0 ESD protection due to its 5 ns trr, 10 pF capacitance at 1 V VR, and low 400 mV VF at 10 mA - all parameters directly supporting signal integrity on 480 Mbps differential data lines while clamping transients to safe levels.
Is the 1PS59SB16,115 RoHS compliant and halogen-free?
Yes, the 1PS59SB16,115 meets RoHS Directive 2011/65/EU and is halogen-free per Nexperia's product compliance documentation. The SC59 package uses lead-free terminations and environmentally compliant molding compound, consistent with Nexperia's standard for automotive and industrial-grade discretes.
