Product details

Overview

1N4148,113 from Nexperia is a high-speed switching diode in a hermetically sealed glass SOD27 (DO-35) package, rated for 100 V repetitive peak reverse voltage, 450 mA repetitive peak forward current, and 4 ns maximum reverse recovery time. It serves as a general-purpose fast-switching element in signal routing, clamping, and protection circuits across consumer and industrial electronics.

For engineers reviewing the 1N4148,113 datasheet, 1N4148,113 pinout, 1N4148,113 application, or 1N4148,113 equivalent, key selection criteria include reverse recovery time, junction temperature limit (200 °C), thermal resistance (350 K/W), and compatibility with axial-leaded PCB layouts requiring low capacitance (≤4 pF) and fast transient response.

Technical Context

The 1N4148,113 is fabricated using planar silicon technology and optimized for high-speed digital and analog switching where low stored charge and rapid turn-off are critical. Its design targets minimal reverse recovery charge (Q_rr) and low forward recovery voltage (≤2.5 V), enabling reliable operation in 1–10 MHz clocked logic interfaces and pulse shaping networks.

It operates within a storage temperature range of −65 °C to +200 °C and maintains stable reverse leakage (≤25 nA at 20 V, 25 °C) while delivering ≤1 V forward voltage at 10 mA. Thermal performance is defined for FR4 PCB mounting with 10 mm lead length, yielding R_th(j-a) = 350 K/W.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - supports DC/AC signal paths up to 100 V peak reverse bias without breakdown
t_rr	4 ns - enables clean edge transitions in >10 MHz digital switching applications
C_d	4 pF - minimizes capacitive loading on high-frequency signal lines and logic nodes
I_FRM	450 mA - handles short-duration current surges in clamp and snubber circuits
T_j max	200 °C - allows sustained operation in thermally constrained enclosures or near power components
V_F @ 10 mA	1 V - ensures low conduction loss in low-current logic-level detection and steering functions
R_th(j-a)	350 K/W - defines thermal derating curve for ambient temperatures above 25 °C on standard FR4

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4448,113	Lower V_F (0.62–0.72 V @ 5 mA); identical t_rr, package, and V_RRM	Better suited for ultra-low-current biasing where <5 mA forward drive is used	Select 1N4448,113 when minimizing forward drop at sub-10 mA levels is critical; otherwise 1N4148,113 offers broader current-range consistency
FDLL4148	Same electrical specs; SOD-123 surface-mount package instead of axial DO-35	Requires PCB redesign for SMT assembly; not suitable for through-hole prototyping or legacy boards	Choose FDLL4148 only for new SMT designs prioritizing board space savings; retains full functional equivalence in circuit behavior

Compared with 1N4448,113 and FDLL4148, the 1N4148,113 delivers optimal balance of forward voltage predictability across 1–100 mA, proven axial-leaded mechanical robustness, and seamless integration into existing DO-35 footprints-making it the default choice for general-purpose high-speed switching where layout flexibility and test-point access matter.

FAQ

What is the maximum reverse voltage rating for the 1N4148,113?

The 1N4148,113 has a repetitive peak reverse voltage (V_RRM) and continuous reverse voltage (V_R) rating of 100 V. This means it can safely block up to 100 V in reverse bias under normal operating conditions. Exceeding this value risks avalanche breakdown or permanent damage. The rating applies with device mounted on FR4 PCB per datasheet test conditions.

Does the 1N4148,113 have a specified reverse recovery time?

Yes, the 1N4148,113 has a maximum reverse recovery time (t_rr) of 4 ns when switched from I_F = 10 mA to I_R = 60 mA with R_L = 100 Ω and measured at I_R = 1 mA. This value is confirmed in the official Nexperia datasheet and defines its suitability for high-frequency switching applications up to ~10 MHz.

What package type does the 1N4148,113 use?

The 1N4148,113 uses the SOD27 (also known as DO-35) package: a hermetically sealed axial-leaded glass body with two leads and a cathode band marking. Its dimensions are standardized per JEDEC DO-35, with 25.4 mm lead spacing and 4.25 mm body length, ensuring compatibility with legacy through-hole assembly processes.

Can the 1N4148,113 be used in RF detector circuits?

Yes, the 1N4148,113 is suitable for RF detector applications due to its low diode capacitance (≤4 pF at 0 V), fast switching (4 ns t_rr), and stable leakage (<25 nA at 20 V, 25 °C). These characteristics enable accurate envelope detection in AM receivers and crystal radios operating from 1 MHz to 30 MHz without significant signal attenuation or detuning.

What is the forward voltage of the 1N4148,113 at 10 mA?

The forward voltage (V_F) of the 1N4148,113 is guaranteed to be ≤1 V at I_F = 10 mA and T_j = 25 °C. Typical values are lower (~0.85 V), but design margins should use the maximum specification. This V_F remains stable across temperature and supports predictable voltage drop in clamping and steering functions.
