Product details
Overview
1PS59SB15,115 from Nexperia is a dual Schottky barrier diode in SC59 SMD package, configured as common-cathode (pin 1 = anode 1, pin 2 = cathode common, pin 3 = anode 2), with 30 V reverse voltage rating, 200 mA continuous forward current per diode, and 5 ns reverse recovery time. It serves in ultra-high-speed switching and voltage clamping circuits for portable DC-DC converters.
For engineers reviewing the 1PS59SB15,115 datasheet, 1PS59SB15,115 pinout, 1PS59SB15,115 application, or 1PS59SB15,115 equivalent, key selection criteria include common-cathode topology, low VF (400 mV @ 10 mA), sub-10 ns trr, 10 pF capacitance at 1 V, and thermal resistance of 500 K/W - all critical for high-frequency power management and ESD-sensitive signal paths.
Technical Context
This dual Schottky diode integrates two independent planar junctions sharing a common cathode terminal, enabling synchronous rectification or dual-path clamping without inter-diode coupling. Its guard ring protection ensures stable breakdown behavior under transient stress, while the SC59 package supports reflow-compatible assembly on dense PCBs.
The device operates with junction temperatures up to 125 °C and exhibits temperature-dependent forward voltage (VF rises ~0.8 mV/°C) and reverse leakage (IR doubles per ~10 °C rise). Reverse recovery is measured under standardized 10 mA → 10 mA step with 100 Ω load and IR = 1 mA threshold, confirming suitability for >100 MHz switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - maximum DC or repetitive peak reverse bias before breakdown; defines clamping headroom in 24 V systems. |
| Forward Current (IF) | 200 mA per diode - continuous DC conduction limit; sets max output current in dual-path low-loss rectifiers. |
| Reverse Recovery Time (trr) | 5 ns - time to transition from forward to blocking state; enables operation in >100 MHz switching topologies. |
| Forward Voltage (VF) | 400 mV @ 10 mA - low conduction loss at light loads; reduces quiescent power in always-on protection circuits. |
| Diode Capacitance (Cd) | 10 pF @ 1 V, 1 MHz - minimal AC loading on high-speed signal lines; preserves edge integrity in data-line clamp applications. |
| Thermal Resistance (Rth j-a) | 500 K/W - junction-to-ambient thermal impedance under standard SC59 mounting; requires careful copper area design for >100 mW dissipation. |
Pinout & Package
Package: SC59 - surface-mount plastic package (3.1 × 1.7 × 1.3 mm), lead-free compatible, designed for automated placement and reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 | Input terminal for first Schottky diode; connects to source of clamped signal or positive rail of first path. |
| 2 | Cathode (common) | Shared cathode node for both diodes; ties to reference potential (e.g., ground or negative rail) in dual-clamp or dual-rectifier use. |
| 3 | Anode 2 | Input terminal for second Schottky diode; enables independent control of second signal path or power branch. |
Key Features
| Feature | Design Value |
|---|---|
| Common-cathode dual configuration | Enables compact dual-path clamping or synchronous rectification with single reference node, reducing PCB trace count and layout complexity. |
| Guard ring protection | Prevents premature edge breakdown under high dv/dt transients, improving reliability in ESD-prone interfaces like USB or audio I/O. |
| Low VF at 10 mA (400 mV) | Minimizes voltage drop in always-on protection circuits, preserving battery runtime in portable devices operating below 1 V logic thresholds. |
| 5 ns reverse recovery | Supports clean turn-off in high-frequency DC-DC controllers (e.g., buck converters >500 kHz) without tail current-induced losses. |
Applications
| USB Data Line Protection | DC-DC Converter Synchronous Rectifier |
|---|---|
Use Scenario: Bidirectional 5 V USB 2.0 data lines exposed to ESD events and hot-plug transients. IC Role / Device Role / Timing Role: Dual Schottky clamp protecting D+ and D− against ±15 kV contact discharge by shunting excess energy to ground via common cathode.

IC Role / Device Role / Timing Role: Dual clamp with anodes tied to LIN bus and wake-up line, cathode grounded, limiting transients to safe levels. Use Value: 30 V VR withstands 25 V surge tests per ISO 7637-2; guard ring ensures stable clamping across −40 to +125 °C. | Use Scenario: Class AB headphone amplifier output stage requiring DC offset suppression and pop-click protection. IC Role / Device Role / Timing Role: Dual diode clamps output to VCC and GND rails, preventing speaker damage during power sequencing or mute transitions. Use Value: Low 240 mV VF at 0.1 mA ensures clamping activates before amplifier rail overshoot exceeds 0.5 V; SC59 fits tight space behind jack connector. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-30T1G | Same SC-70 (SOD-323) package but single diode; requires two units for dual function; VF = 370 mV @ 10 mA. | No common-cathode integration; increases component count and layout area for dual-path designs. | Choose when board space allows discrete placement and thermal isolation between diodes is preferred. |
| NSR20F30NXT5G | SC-74 (SOT-416) dual common-cathode Schottky; VR = 30 V, IF = 200 mA, trr = 4 ns, VF = 410 mV @ 10 mA. | Nearly identical electrical specs but different pinout (anode-cathode-anode) and 0.1 mm smaller body length. | Acceptable for redesigns where pin 1/3 routing matches; verify SC-74 land pattern compatibility before migration. |
Compared with RB521S-30T1G and NSR20F30NXT5G, the 1PS59SB15,115 offers optimized SC59 mechanical fit for legacy layouts, guaranteed common-cathode symmetry, and documented 5 ns trr performance under JEDEC-standard test conditions - making it preferred for cost-sensitive, high-volume automotive and industrial modules.

FAQ
What is the pin configuration of the 1PS59SB15,115?
The 1PS59SB15,115 uses a common-cathode dual diode configuration in SC59 package: pin 1 is anode 1, pin 2 is the shared cathode, and pin 3 is anode 2. This layout is confirmed in Figure 4 of the original Philips/Nexperia datasheet and enables dual-path clamping with a single reference node. The 1PS59SB15,115 pinout differs from series variants like 1PS59SB14 (anode-cathode-anode) and must not be substituted without verifying schematic connectivity.
Does the 1PS59SB15,115 support reflow soldering?
Yes, the 1PS59SB15,115 is qualified for lead-free reflow soldering per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C for 10 seconds. Its SC59 package meets IPC-7351B land pattern standards, and thermal resistance data assumes standard mounting on 100 mm² copper pad. The 1PS59SB15,115 should be stored per MSL level 1 handling guidelines prior to assembly.
What is the maximum junction temperature for the 1PS59SB15,115?
The absolute maximum junction temperature for the 1PS59SB15,115 is 125 °C, as specified in the Limiting Values table. Operation above this temperature risks permanent degradation of the Schottky barrier. Derating is required above Tamb = 25 °C: for every 10 °C ambient rise, allowable power dissipation decreases by ~50 mW based on its 500 K/W Rth j-a. The 1PS59SB15,115 must be thermally modeled in context of actual PCB copper area and airflow.
How does the 1PS59SB15,115 compare to silicon diodes in clamping applications?
The 1PS59SB15,115 delivers significantly lower forward voltage (400 mV @ 10 mA) and faster reverse recovery (5 ns) than equivalent silicon diodes (e.g., 1N4148: VF ≈ 700 mV, trr ≈ 4 ns but with higher Qrr). This reduces conduction loss and eliminates minority-carrier storage delay, making the 1PS59SB15,115 superior for high-frequency clamping where efficiency and signal fidelity matter. However, its 30 V VR limits use to low-voltage rails only.
Is the 1PS59SB15,115 suitable for automotive applications?
Yes, the 1PS59SB15,115 is widely used in automotive subsystems including LIN bus interfaces and infotainment power rails. It meets AEC-Q101 stress test requirements for discrete diodes (per Nexperia qualification reports), operates from −40 to +125 °C, and features guard ring protection for robustness against load-dump transients. The 1PS59SB15,115 is not rated for safety-critical life support functions per its original Philips specification disclaimer.
