Product details
Overview
1N4454-TAP from Vishay Semiconductors is a silicon epitaxial planar fast-switching small-signal diode rated for 100 V peak reverse voltage, 150 mA average forward current, and 4 ns reverse recovery time, used in high-frequency rectification and signal demodulation circuits.
For engineers reviewing the 1N4454-TAP datasheet, 1N4454-TAP pinout, 1N4454-TAP application, or 1N4454-TAP equivalent, key selection criteria include reverse recovery time, leakage current at 75 V, junction temperature limit, and DO-35 glass package compatibility with automated placement systems.
Technical Context
The 1N4454-TAP operates as a unidirectional PN junction rectifier with low junction capacitance (≤2 pF) and fast carrier recombination enabling operation up to 100 MHz. Its 4 ns trr and 100 nA IR at 50 V support high-speed switching in RF detector and clamp circuits.
Thermal design relies on its 350 °C/W junction-to-ambient thermal resistance and 175 °C maximum junction temperature, with power derating required above 25 °C ambient per the admissible dissipation curve. The DO-35 glass case provides hermetic sealing and stable parameter performance across –65 to +175 °C storage range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast-switching small-signal diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4148WS-7-F | Smaller SOD-323 package (1.7 × 1.3 mm), 4 ns trr, 100 V VRM, but 150 mA IF(AV) derated to 100 mA at TA > 75 °C | Surface-mount only; unsuitable for through-hole prototyping or axial wave-solder processes | Select when board space is constrained and reflow assembly is used |
| BAS16,215 | DO-35 package, 4 ns trr, 80 V VRM (lower than 1N4454-TAP's 100 V), 200 mA IF(AV), 10 nA IR at 50 V | Lower reverse voltage margin limits use in 75–100 V transient suppression | Select when tighter leakage spec (<10 nA) is prioritized over peak voltage capability |
Compared with 1N4454-TAP, 1N4148WS-7-F offers footprint reduction at the cost of thermal derating, while BAS16,215 trades 20 V reverse margin for lower leakage-making 1N4454-TAP optimal for 100 V-rated RF and power-supply feedback where both speed and voltage headroom are critical.

FAQ
What is the maximum reverse voltage rating for the 1N4454-TAP?
The 1N4454-TAP has a peak reverse voltage (VRM) rating of 100 V and a maximum DC reverse voltage (VR) of 75 V. This dual rating means it can withstand repetitive 100 V transient spikes but is rated for continuous 75 V reverse bias. Engineers must ensure system-level transients do not exceed 100 V and steady-state reverse bias remains ≤75 V to maintain reliability. The 1N4454-TAP datasheet specifies these limits under standard test conditions at 25 °C ambient.
Does the 1N4454-TAP have a specified reverse recovery time?
Yes, the 1N4454-TAP has a guaranteed maximum reverse recovery time (trr) of 4 ns, measured at IF = 10 mA, IR = 1 mA, VR = 6 V, and RL = 100 Ω. This value is confirmed in Vishay's Document Number 88110 and is critical for high-frequency applications such as RF detection and pulse shaping. The 1N4454-TAP achieves this performance via silicon epitaxial planar construction and optimized doping profiles.
What package type is used for the 1N4454-TAP?
The 1N4454-TAP uses the DO-35 (also designated DO-204AH) glass axial package, with approximate dimensions of 2.0 mm diameter × 4.5 mm length and 2.54 mm lead spacing. It weighs about 0.13 g and is supplied in 52 mm-wide ammo tape (F2) or 13-inch reels (F3). The 1N4454-TAP's hermetic glass construction ensures long-term parameter stability in humid or chemically aggressive environments.
What is the forward voltage drop of the 1N4454-TAP at 10 mA?
The 1N4454-TAP exhibits a maximum forward voltage drop (VF) of 1.0 V at 10 mA forward current and 25 °C ambient temperature. This specification appears in the Electrical Characteristics table of Vishay's official datasheet (Document Number 88110). The 1N4454-TAP's VF is typical for fast silicon switching diodes and directly impacts conduction loss in low-current signal routing and bias networks.
How does the 1N4454-TAP perform at elevated temperatures?
The 1N4454-TAP maintains operation up to a maximum junction temperature (TJ) of 175 °C and a storage temperature range of –65 to +175 °C. Its leakage current increases with temperature-e.g., rising to ~1 µA at 20 V and 100 °C-but remains within specification. Thermal resistance junction-to-ambient (RθJA) is 350 °C/W, requiring derating above 25 °C ambient per the published power dissipation curve. The 1N4454-TAP's thermal behavior is fully characterized in Vishay's Document Number 88110.
