Product details

Overview

1N4148W-13-F from Diodes Incorporated is a surface-mount fast-switching silicon signal diode in SOD-123 package, rated for 100 V peak repetitive reverse voltage, 300 mA forward current, and 4 ns reverse recovery time. It delivers low forward voltage (0.715 V at 1 mA), low junction capacitance (2 pF), and operates across –55 °C to +150 °C - widely deployed in high-speed digital logic clamping, waveform shaping, and protection circuits in industrial control modules.

For engineers reviewing the 1N4148W-13-F datasheet, 1N4148W-13-F pinout, 1N4148W-13-F application, or 1N4148W-13-F equivalent, key selection criteria include reverse recovery speed, forward voltage consistency at low currents, thermal resistance (315 °C/W), junction-to-ambient derating behavior, and RoHS-compliant green packaging suitability for automated SMT assembly.

Technical Context

This diode operates as a unidirectional, low-capacitance switching element optimized for signal-level applications where rapid turn-off and minimal charge storage are critical. Its 4 ns t_RR enables reliable operation in 10–50 MHz clock line clamping and TTL/CMOS interface protection.

Designed with a planar epitaxial structure and alloy-42 leadframe, it achieves stable V_F performance across temperature and maintains <1 µA leakage at 75 V reverse bias (T_A = 25 °C), supporting precision signal routing in mixed-signal PCBs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - supports DC blocking and transient suppression in 24 V and 48 V industrial bus interfaces without breakdown
t_RR	4 ns max - ensures minimal switching distortion in >20 MHz digital signal paths and pulse shaping networks
V_F	0.715 V max at I_F = 1 mA - reduces power loss and voltage offset in low-current bias and sensing circuits
C_T	2.0 pF max at V_R = 0 V - preserves signal integrity in RF-coupled and high-frequency timing circuits
R_θJA	315 °C/W - defines thermal derating slope on standard FR-4 with 2"×2" copper pads; limits continuous dissipation to 400 mW at 25 °C ambient
I_F	300 mA continuous - sufficient for driving LED indicators, optocoupler inputs, and small-signal relay coils

Pinout & Package

Package: SOD-123 - surface-mount plastic case with cathode band marking, 0.01 g mass, UL 94V-0 rating, moisture sensitivity level 1, and matte tin-plated alloy-42 terminals solderable per MIL-STD-202.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential node in clamping or rectification path; requires thermal pad design for >150 mA operation
Cathode	Forward current exit / reverse-blocking terminal	Marked by band; ties to higher-potential rail or logic output; determines polarity in ESD protection configurations

Key Features

Feature	Design Value
Fast reverse recovery	4 ns maximum enables clean edge transitions in 25+ MHz clock distribution and data line termination
Low forward voltage	0.715 V at 1 mA minimizes voltage drop in precision reference clamping and analog switch bias networks
Low junction capacitance	2 pF at 0 V allows use in 100+ MHz RF detector and mixer local oscillator coupling paths
Green, lead-free construction	Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets IPC-1752A reporting requirements

Applications

Digital Logic Clamping

ESD Protection Interface

Use Scenario: Preventing overshoot/undershoot on 3.3 V CMOS input pins during hot-plug events or signal reflections.

IC Role / Device Role / Timing Role: Fast-clamp diode shunting transients to V_CC or GND before internal gate oxide breakdown.

Use Value: 4 ns t_RR and sub-1 µA leakage ensure no DC loading of logic lines while responding within one clock cycle of a 250 MHz system.

Use Scenario: Safeguarding USB 2.0 D+/D− lines against ±8 kV contact discharge per IEC 61000-4-2 Level 4.

IC Role / Device Role / Timing Role: Low-capacitance steering diode diverting ESD current away from PHY transceiver inputs.

Use Value: 2 pF C_T avoids signal integrity degradation above 480 Mbps; 100 V V_RRM withstands post-clamp residual voltage.

Waveform Shaping Circuit

Power Supply Sequencing

Use Scenario: Converting sine wave oscillator outputs into clean square waves for clock fanout buffers.

IC Role / Device Role / Timing Role: Passive clipping element limiting amplitude swing to logic threshold levels.

Use Value: Consistent 0.715 V V_F at 1 mA ensures repeatable clipping voltage across production lots and temperature range.

Use Scenario: Enabling controlled power-up order between 5 V and 3.3 V rails using diode-or configuration.

IC Role / Device Role / Timing Role: Isolation diode preventing backfeed and enabling staggered enable timing.

Use Value: 300 mA I_F rating supports sequencing of moderate-current rails; 315 °C/W R_θJA permits direct PCB trace routing without heatsinking.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fast-switching diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4148WS-7-F	SOD-323 package (smaller footprint, higher R_θJA = 400 °C/W), identical electrical specs	Better suited for space-constrained portable designs; less thermal margin at >100 mA	Select when board area is critical and average forward current stays below 100 mA
BAV16W-13-F	Same SOD-123 package; slightly higher V_F (0.855 V at 10 mA) but identical t_RR, C_T, and V_RRM	Functionally interchangeable in most clamping roles; minor V_F difference negligible in high-impedance logic interfaces	Choose for cost-sensitive BOMs where 0.14 V higher V_F at 10 mA does not impact circuit margin

Compared with 1N4148W-13-F, the 1N4148WS-7-F trades thermal robustness for miniaturization, while the BAV16W-13-F offers identical speed and voltage ratings with a modest forward voltage penalty-making both viable depending on layout constraints and bias current profile.

FAQ

What is the maximum junction temperature for continuous operation?

The 1N4148W-13-F has an operating junction temperature range of –55 °C to +150 °C. For continuous operation at full 300 mA forward current, thermal design must limit junction temperature to ≤150 °C using the specified R_θJA = 315 °C/W and appropriate PCB copper area. Derating begins linearly above 25 °C ambient, reaching zero power at 150 °C ambient.

Is this part qualified for automotive use?

The 1N4148W-13-F is not AEC-Q101 qualified. For automotive applications, Diodes specifies the 1N4148WQ-13-F variant, which undergoes additional stress testing, PPAP documentation, and is manufactured in IATF 16949-certified facilities. The "Q" suffix denotes automotive qualification; standard 1N4148W-13-F is intended for industrial and commercial use only.

How does the SOD-123 package affect PCB layout?

The SOD-123 footprint requires 0.90 mm pad width (X), 4.05 mm pad length (X1), and 0.95 mm spacing (Y) per Diodes' recommended layout. Its 3.65 mm body height and 0.30 mm lead thickness support standard reflow profiles. Thermal relief must be minimized on anode/cathode pads to maintain 315 °C/W R_θJA performance under sustained load.

Can this diode replace older through-hole 1N4148 variants?

Yes - the 1N4148W-13-F provides identical electrical performance to legacy axial 1N4148 diodes but in a surface-mount SOD-123 package. Key differences include lower profile, automated assembly compatibility, and tighter V_F and t_RR distributions. No circuit redesign is needed, though PCB land pattern must match SOD-123 dimensions and thermal pad rules.
