Product details
Overview
1PS59SB10,115 from Nexperia is a planar Schottky barrier single diode in SC59 SMD package, rated for 30 V reverse voltage, 200 mA continuous forward current, and 5 ns reverse recovery time, used as a blocking diode in low-voltage DC-DC converter output stages.
For engineers reviewing the 1PS59SB10,115 datasheet, 1PS59SB10,115 pinout, 1PS59SB10,115 application, or 1PS59SB10,115 equivalent, key selection criteria include ultra-fast switching (trr = 5 ns), low VF (400 mV @ 10 mA), guard ring protection, thermal resistance (Rth j-a = 500 K/W), and SC59 footprint compatibility with space-constrained portable power rails.
Technical Context
This discrete Schottky diode operates without minority-carrier storage, enabling nanosecond-scale switching transitions. Its guard ring structure suppresses edge breakdown under high dv/dt, supporting reliable clamping in inductive load snubbers.
The SC59 package uses a leadframe-based construction with gull-wing leads, optimized for reflow soldering and thermal dissipation up to 125 °C junction temperature. Electrical behavior is characterized at Tamb = 25 °C, with derating applied above that ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 30 V maximum - supports 24 V rail clamping and 12 V system blocking without avalanche conduction |
| IF (Continuous Forward Current) | 200 mA - sufficient for bias supply paths and low-power signal-level rectification |
| trr (Reverse Recovery Time) | 5 ns - enables operation in >100 MHz switching circuits without tail current losses |
| VF (Forward Voltage) | 400 mV @ 10 mA - reduces conduction loss in battery-powered 3.3 V/5 V logic supply hold-up paths |
| IR (Reverse Current) | 2 µA @ 25 V - ensures minimal leakage in high-impedance voltage sensing nodes |
| Rth j-a (Thermal Resistance) | 500 K/W - requires PCB copper area ≥ 25 mm² for safe 200 mA operation at 70 °C ambient |
Pinout & Package
SC59 plastic SMD package: 3-pin, gull-wing leadform, 2.7–3.1 mm length, 1.3–1.7 mm width, 1.0–1.3 mm height, 0.6–0.9 mm lead pitch. Pin 1 = anode (a), Pin 2 = no connection (n.c.), Pin 3 = cathode (k).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Forward current entry point; connects to higher-potential node in blocking or clamping configuration |
| 2 | No Connection | Internally unconnected; must remain floating - not usable as thermal pad or ground tie |
| 3 | Cathode | Forward current exit point; ties to lower-potential node or return path in DC-DC output stage |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Prevents premature edge breakdown under transient overvoltage, improving reliability in ESD-prone USB or I/O line protection |
| Low VF at low IF | 240 mV @ 0.1 mA enables use in micro-power wake-up detection circuits without loading source |
| Ultra-fast trr | 5 ns recovery supports synchronous rectifier emulation in high-frequency buck converters (>2 MHz) |
| SC59 footprint | Standardized 3-pin SMD outline allows drop-in replacement with other SC59 Schottky diodes in existing layouts |
Applications
| USB Port Protection | DC-DC Output Blocking |
|---|---|
Use Scenario: Preventing backfeed from downstream USB peripherals into host VBUS during suspend mode. IC Role / Device Role / Timing Role: Single Schottky blocking diode placed between host VBUS and peripheral input. Use Value: 400 mV forward drop minimizes voltage loss on 5 V rail; 2 µA IR prevents standby current drain. | Use Scenario: Isolating output of a step-down converter from shared system rail during power sequencing. IC Role / Device Role / Timing Role: Output-side OR-ing diode in dual-supply redundancy architecture. Use Value: 5 ns trr avoids cross-conduction during fast rail transitions; SC59 footprint fits tight board spacing. |
| Logic-Level Clamping | Low-Power Sensor Biasing |
Use Scenario: Limiting GPIO voltage excursions beyond 3.3 V in mixed-voltage microcontroller interfaces. IC Role / Device Role / Timing Role: Clamp diode tied between I/O pin and 3.3 V rail. Use Value: Guard ring ensures stable clamping at 30 V transients; low VF avoids false logic-high assertion. | Use Scenario: Providing bias current to photodiode or thermistor measurement circuits in battery-operated sensors. IC Role / Device Role / Timing Role: Low-leakage forward path for precision analog front-end reference current. Use Value: 2 µA IR preserves nanoampere-level sensor bias accuracy; 240 mV VF @ 0.1 mA maintains headroom. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G | Higher IF (200 mA same), but VF = 370 mV @ 10 mA; Rth j-a = 430 K/W; SOD-523 package (smaller, 1.2 × 0.8 mm) | Suitable for tighter layouts but requires rework of stencil and pick-and-place setup | Select when board area is critical and thermal margin allows 430 K/W |
| BAT54C,215 | Double-diode configuration (common-cathode); VF = 420 mV @ 10 mA; same SC59 package; VR = 30 V | Provides dual-channel capability but occupies same footprint - useful for matched pair clamping | Select when dual-diode symmetry or channel matching is required in protection networks |
Compared with RB520S-30T1G and BAT54C,215, the 1PS59SB10,115 offers the only single-diode SC59 variant with n.c. pin 2, simplifying layout for unidirectional blocking where second diode or alternate pinout is unnecessary.

FAQ
What is the pin configuration of the 1PS59SB10,115?
The 1PS59SB10,115 has a 3-pin SC59 package with Pin 1 = anode, Pin 2 = no connection (internally unconnected), and Pin 3 = cathode. This single-diode configuration differs from double-diode variants like 1PS59SB14, which repurpose Pin 2 as a second cathode.
Does the 1PS59SB10,115 support reflow soldering?
Yes, the 1PS59SB10,115 is qualified for standard Pb-free reflow soldering per J-STD-020. Its SC59 package meets JEDEC moisture sensitivity level MSL3 and withstands peak temperatures up to 260 °C for 30 seconds, consistent with IPC-A-610 Class 2 requirements.
What is the maximum junction temperature for continuous operation of the 1PS59SB10,115?
The 1PS59SB10,115 has a maximum junction temperature (Tj) of 125 °C. To maintain this limit at 200 mA continuous forward current, PCB copper area must be ≥25 mm² and ambient temperature ≤70 °C, given its Rth j-a of 500 K/W.
Is the 1PS59SB10,115 suitable for automotive applications?
The 1PS59SB10,115 is not AEC-Q101 qualified and lacks automotive-grade screening. While it operates within -65 °C to +150 °C storage range, Nexperia recommends AEC-Q101-compliant alternatives such as PMEG3010CPA for under-hood automotive use.
How does the guard ring in the 1PS59SB10,115 improve reliability?
The guard ring in the 1PS59SB10,115 surrounds the active Schottky junction to suppress electric field crowding at the silicon edge, preventing premature avalanche breakdown during voltage transients. This extends operational life in ESD-sensitive interfaces like USB and I²C lines.
