Product details
Overview
1PS193,115 from Nexperia is a high-speed switching diode in SC59 SMD package, with 4 ns reverse recovery time, 80 V continuous reverse voltage, and 500 mA repetitive peak forward current, used for fast signal routing and clamping in surface-mounted power management circuits.
For engineers reviewing the 1PS193,115 datasheet, 1PS193,115 pinout, 1PS193,115 application, or 1PS193,115 equivalent, key selection criteria include reverse recovery time, junction-to-ambient thermal resistance, diode capacitance at zero bias, forward voltage at 10 mA, and SC59 package compatibility with automated placement systems.
Technical Context
The 1PS193,115 employs planar silicon technology to achieve sub-4 ns trr with low stored charge, enabling clean edge transitions in high-frequency switching nodes. Its SC59 package features a three-terminal configuration with Pin 2 internally unconnected, minimizing parasitic inductance.
Electrical behavior is characterized by low VF (740 mV typ. at IF = 10 mA), ultra-low IR (30 nA max. at VR = 25 V), and Cd ≤ 1.5 pF at VR = 0 V - all critical for RF detector, sample-and-hold, and high-speed logic interface applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| trr | 4 ns max - enables operation up to ~100 MHz switching without tail current distortion |
| VRRM | 85 V peak - supports transient suppression in 48 V industrial bus interfaces |
| IFRM | 500 mA peak - handles pulsed loads in DC-DC converter snubbers and flyback clamp circuits |
| Cd | 1.5 pF max at 0 V - minimizes signal loading in 50 Ω RF paths and high-speed data lines |
| Rth j-a | 500 K/W on FR4 - defines derating curve for ambient temperatures above 70 °C in compact PCB layouts |
| VF @ 10 mA | 740 mV typ. - reduces conduction loss in low-voltage logic-level clamping networks |
Pinout & Package
Package: SC59 - 3-pin small-outline plastic SMD package (2.7 × 1.3 × 0.9 mm), optimized for reflow soldering and high-density board assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Forward current entry point; connects to drive source or positive rail in clamp configurations |
| 2 | Not connected | No internal bond wire; must remain floating - not usable as thermal pad or ground tie |
| 3 | Cathode | Forward current exit; ties to reference node (e.g., ground or negative rail) in switching paths |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | 4 ns trr enables clean signal edge integrity in >50 MHz digital timing paths |
| Low junction capacitance | 1.5 pF at 0 V reverse bias preserves bandwidth in RF detector and mixer front-ends |
| Thermal performance on FR4 | 500 K/W Rth j-a allows 215 mA continuous operation at 70 °C ambient without heatsinking |
| Low leakage at high temperature | 100 μA max IR at VR = 80 V and Tj = 150 °C ensures stable bias in hot automotive environments |
Applications
| RF Signal Detection | Digital Logic Clamping |
|---|---|
Use Scenario: Demodulating AM signals in portable radio receivers using envelope detection. IC Role / Device Role / Timing Role: High-speed diode acting as passive envelope detector with minimal phase delay. Use Value: 4 ns trr and 1.5 pF capacitance preserve modulation fidelity up to 30 MHz carrier frequencies. | Use Scenario: Protecting CMOS input pins from overvoltage transients in microcontroller-based sensor interfaces. IC Role / Device Role / Timing Role: Clamp diode limiting input voltage to VDD + 0.7 V and GND − 0.3 V. Use Value: Low VF (740 mV typ.) and negligible capacitance prevent signal degradation during normal operation. |
| DC-DC Converter Snubber | Flyback Transformer Clamp |
Use Scenario: Absorbing leakage inductance spikes across synchronous rectifier MOSFETs in buck converters. IC Role / Device Role / Timing Role: Fast-recovery diode in RC snubber network to suppress ringing. Use Value: 4 ns trr prevents reverse recovery oscillation that would otherwise couple noise into control loop feedback. | Use Scenario: Clamping voltage spikes across primary windings of isolated flyback transformers. IC Role / Device Role / Timing Role: Repetitive peak-rated diode conducting energy from transformer leakage inductance. Use Value: 500 mA IFRM and 85 V VRRM support reliable clamp operation under 24–48 V input conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAT54C,215 | Lower VRRM (30 V), higher Cd (10 pF), dual-diode configuration in SOT-23 | Not suitable for >40 V reverse bias; better for low-voltage logic protection than RF detection | Select only when circuit operates below 30 V and dual-cathode topology matches layout |
| 1N4148W,115 | Higher trr (4 ns same), but larger SOD-123 package (3.7 × 1.6 mm) and higher Rth j-a (625 K/W) | Less suitable for ultra-dense layouts; thermal derating more aggressive above 60 °C | Prefer when legacy footprint compatibility is required and board space permits larger outline |
Compared with BAT54C,215 and 1N4148W,115, the 1PS193,115 delivers superior RF performance due to its 1.5 pF capacitance and SC59 footprint, while maintaining identical trr - making it optimal for space-constrained, high-frequency signal path applications where low parasitics are critical.

FAQ
What is the maximum reverse recovery time specified for the 1PS193,115?
The 1PS193,115 has a maximum reverse recovery time (trr) of 4 ns under standard test conditions (IF = 10 mA switched to IR = 10 mA, RL = 100 Ω, measurement at IR = 1 mA). This value is confirmed in the original NXP product data sheet and remains valid under Nexperia's continued product stewardship.
Is Pin 2 of the 1PS193,115 electrically functional or internally disconnected?
Pin 2 of the 1PS193,115 is explicitly marked "not connected" in the official datasheet pinning diagram and schematic symbol. It has no internal bond wire or semiconductor connection and must remain unconnected in PCB layout - it is not intended for thermal relief or grounding.
What is the continuous forward current rating for the 1PS193,115 at 70 °C ambient temperature?
At Tamb = 70 °C on an FR4 board, the 1PS193,115 supports approximately 150 mA continuous forward current, derived from the derating curve in Figure 2 of the datasheet (where IF drops linearly from 215 mA at 25 °C to 0 mA at 125 °C).
Does the 1PS193,115 meet automotive AEC-Q101 qualification requirements?
The 1PS193,115 is not listed in Nexperia's AEC-Q101 qualified portfolio. It is a standard high-speed diode intended for industrial and consumer applications; for automotive use, engineers should select Nexperia's AEC-Q101-qualified equivalents such as the PNE30030EP or BAS16XV2.
What marking code identifies the 1PS193,115 on the device body?
The 1PS193,115 is marked with the code "F3T" on its top surface, as specified in the "Marking code" note of the original NXP datasheet. This laser-marked identifier is visible under 20× magnification and aligns with Nexperia's standardized SMD diode marking convention.
