Product details
Overview
PRLL5819,115 from Nexperia is a Schottky barrier diode in a hermetically sealed glass SOD87 surface-mount package, rated for 40 V repetitive peak reverse voltage (VRRM), 1 A average forward current (IF(AV)) at 60 °C ambient, and 600 mV forward voltage at 1 A. It delivers low switching losses and fast recovery for polarity protection and low-power SMPS rectification.
For engineers reviewing the PRLL5819,115 datasheet, PRLL5819,115 pinout, PRLL5819,115 application, or PRLL5819,115 equivalent, key selection criteria include its 40 V VRRM rating, 150 K/W junction-to-ambient thermal resistance, SOD87 package footprint, and cathode-marked glass-body construction suitable for space-constrained, thermally sensitive DC/DC and battery-protection circuits.
Technical Context
The PRLL5819,115 uses planar Schottky technology with guard ring protection to suppress edge breakdown and ensure stable reverse leakage up to 10 mA at 100 °C. Its Implotec™-enhanced SOD87 package provides hermetic sealing and reliable thermal performance under pulsed and continuous conduction.
Designed for low-loss unidirectional conduction, it exhibits 340 mV VF at 0.1 A and 900 mV at 3 A, with 50 pF diode capacitance at 4 V/1 MHz - enabling high-frequency rectification without significant capacitive loading or switching loss penalties.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - maximum repetitive reverse blocking voltage; defines safe operating range in DC bias or flyback clamp applications |
| IF(AV) | 1 A at Tamb = 60 °C - continuous forward current capability under standard PCB mounting conditions |
| VF @ 1 A | 600 mV - forward voltage drop determining conduction loss and self-heating in power path design |
| IR @ VRRM | 1 mA max at 25 °C - reverse leakage limiting standby power loss and thermal runaway risk |
| Rth j-a | 150 K/W - thermal resistance defining junction temperature rise per watt of dissipated power |
| Cd @ 4 V | 50 pF - junction capacitance affecting high-frequency switching noise and EMI behavior |
Pinout & Package
SOD87 is a hermetically sealed glass surface-mount package with two terminals and cathode marking (band) on the body. Dimensions: L = 3.3–3.7 mm, D = 1.8–2.0 mm, H = 2.0–2.1 mm; weight ≈ 20 mg.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry point | Connected to lower-potential side (e.g., ground or return path) in rectifier or protection configurations |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Marked with band; connects to positive rail in polarity protection or anode of output rectifier |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Suppresses edge leakage and improves long-term reliability under high reverse bias stress |
| Hermetically sealed glass SMD package | Prevents moisture ingress and intermetallic degradation, supporting extended life in humid environments |
| Low VF at 1 A (600 mV) | Reduces conduction loss by ~30 % vs. comparable 40 V Schottkys with VF > 800 mV |
| Fast recovery time | Enables operation up to ~1 MHz without significant reverse recovery charge (Qrr) penalty |
Applications
| Battery Polarity Protection | Low-Power SMPS Output Rectification |
|---|---|
Use Scenario: Prevents damage from reversed battery insertion in portable medical devices and handheld instruments. IC Role / Device Role / Timing Role: Unidirectional blocking element placed in series with input power rail. Use Value: 40 V VRRM and 1 mA IR at 25 °C ensure minimal standby drain and robust reverse blocking without active control circuitry. | Use Scenario: Rectifies 5 V or 12 V secondary-side output in isolated flyback converters under ≤1 A load. IC Role / Device Role / Timing Role: High-efficiency synchronous rectifier alternative where gate drive complexity is undesirable. Use Value: 600 mV VF at 1 A reduces conduction loss versus standard PN diodes, improving efficiency by ≥2 % at light-to-moderate loads. |
| USB Port Overvoltage Clamp | DC Input Reverse Polarity Guard |
Use Scenario: Clamps transient overvoltage on USB VBUS lines during hot-plug events or ESD coupling. IC Role / Device Role / Timing Role: Low-capacitance (50 pF) shunt diode tied between VBUS and ground with series impedance. Use Value: 50 pF capacitance avoids signal integrity degradation on 480 Mbps USB 2.0 data lines while providing 40 V standoff. | Use Scenario: Protects industrial sensor modules powered from field wiring where polarity reversal is possible. IC Role / Device Role / Timing Role: Series-connected Schottky in main DC input path before regulator IC. Use Value: 150 K/W Rth j-a allows direct PCB copper pour heatsinking, sustaining 1 A continuous without external thermal relief. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB140-TB | 40 V VRRM, 1 A IF(AV), but TO-277 package (larger, non-hermetic plastic); VF = 550 mV @ 1 A | Less suitable for moisture-sensitive or miniaturized designs due to plastic encapsulation and larger footprint | Preferred where cost sensitivity outweighs size or hermeticity requirements |
| SS34-HF | 40 V VRRM, 3 A IF(AV), SMA package; VF = 550 mV @ 1 A; Cd = 100 pF | Higher current rating and larger capacitance limit use in high-speed or space-constrained layouts | Chosen when higher surge tolerance (IFSM = 100 A) or board-level thermal mass is available |
Compared with SB140-TB and SS34-HF, PRLL5819,115 offers superior environmental robustness via hermetic glass packaging and tighter capacitance control (50 pF), making it optimal for compact, high-reliability DC power rails where leakage, size, and moisture resistance are critical.

FAQ
What is the maximum junction temperature for PRLL5819,115?
The absolute maximum junction temperature (Tj) for PRLL5819,115 is 125 °C, as specified in the Absolute Maximum Ratings table. This limit applies under steady-state conditions with proper PCB thermal design; exceeding it risks permanent degradation of the Schottky junction and increased reverse leakage. Derating is required above ambient temperatures where Rth j-a × Pd exceeds the margin to 125 °C.
Does PRLL5819,115 have a cathode marking, and how is it identified?
Yes, PRLL5819,115 features a visible cathode band on the glass body - a darkened or opaque ring near one end. Per the datasheet package outline, this band identifies the cathode terminal, which must be connected toward the higher-potential node in rectifier or polarity protection configurations. The unmarked end is the anode.
Is PRLL5819,115 suitable for automotive applications?
PRLL5819,115 meets AEC-Q101 stress test requirements for discrete semiconductors and is qualified for automotive use per Nexperia's product documentation. Its hermetic SOD87 package, 125 °C Tj rating, and stable IR performance up to 100 °C make it appropriate for engine control module power rails, infotainment system protection, and body electronics where reliability under thermal cycling is critical.
What is the non-repetitive peak forward current rating for PRLL5819,115?
The non-repetitive peak forward current (IFSM) for PRLL5819,115 is 25 A, tested under t = 10 ms half-sine wave conditions with initial junction temperature at maximum and VR = 0. This rating supports brief inrush or fault-current events in power supplies and battery circuits, but repeated surges above 1 A average require thermal analysis using Rth j-a = 150 K/W.
How does the Implotec™ technology in PRLL5819,115 improve performance?
Implotec™ is Philips' proprietary process for enhancing adhesion and hermeticity between the silicon die and glass package in SOD87 devices. In PRLL5819,115, it ensures long-term stability of VF and IR parameters by preventing moisture-induced corrosion and interfacial delamination - directly contributing to the device's 175 °C storage temperature rating and field reliability in harsh environments.
