Product details
Overview
1N914B,113 from NXP Semiconductors (formerly Philips) is a high-speed switching diode in a hermetically sealed SOD27 (DO-35) glass package, featuring 4 ns reverse recovery time, 75 V continuous reverse voltage, and 225 mA repetitive peak forward current. It serves as a fast signal-level switch in digital logic interfaces and pulse shaping circuits.
For engineers reviewing the 1N914B,113 datasheet, 1N914B,113 pinout, 1N914B,113 application, or 1N914B,113 equivalent, key selection criteria include reverse recovery time under 4 ns at IF = 10 mA → IR = 60 mA, forward voltage of 0.62–0.72 V at 5 mA, cathode-marked axial leads, and thermal resistance of 500 K/W junction-to-ambient on FR4 PCB.
Technical Context
The 1N914B,113 is a planar silicon switching diode optimized for low charge storage and rapid carrier sweep-out. Its 4 ns trr (measured at IF = 10 mA → IR = 60 mA, RL = 100 Ω, IR = 1 mA threshold) enables reliable operation in >10 MHz pulse applications.
It operates with a maximum junction temperature of 175 °C and exhibits low diode capacitance (≤4 pF at 1 MHz, VR = 0 V), supporting high-frequency signal routing without significant capacitive loading. Reverse leakage remains ≤5 µA at VR = 75 V and 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time (trr) | 4 ns - enables clean edge transitions in digital clock distribution and pulse generation up to 10 MHz |
| Forward Voltage (VF) | 0.62–0.72 V at 5 mA - minimizes conduction loss in low-current logic clamping and level-shifting |
| Repetitive Peak Reverse Voltage (VRRM) | 100 V - supports transient suppression in 24–48 V industrial control signal lines |
| Diode Capacitance (Cd) | ≤4 pF at 1 MHz, VR = 0 V - preserves signal integrity in RF detector and high-speed sampling circuits |
| Continuous Forward Current (IF) | 75 mA - defines safe DC bias limit for sustained switching in TTL/CMOS interface protection |
| Junction-to-Ambient Thermal Resistance (Rth j-a) | 500 K/W - requires minimal PCB copper area for thermal management in ambient temperatures ≤70 °C |
Pinout & Package
Hermetically sealed axial-leaded SOD27 (DO-35) glass package with cathode indicated by a colored band. Leads are tinned copper-clad steel, compatible with wave and hand soldering per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node during conduction; must be routed with low-inductance trace for fast switching |
| Cathode | Forward current exit / reverse blocking terminal | Marked by colored band; ties to higher-potential node or ground reference in clamp configurations |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | 4 ns reverse recovery time verified under standardized IF→IR step conditions (10 mA → 60 mA, RL = 100 Ω) |
| Low forward voltage | 0.62–0.72 V at 5 mA ensures minimal voltage drop in signal-path clamping and logic-level translation |
| Hermetic glass packaging | SOD27 (DO-35) construction provides long-term reliability in humid or chemically aggressive environments |
| Low junction capacitance | ≤4 pF at zero bias enables use in RF detector stages and high-frequency sample-and-hold inputs |
Applications
| Digital Logic Interface Protection | Pulse Shaping & Edge Generation |
|---|---|
Use Scenario: Clamping input pins of 74HC-series logic ICs against ESD and overvoltage transients in industrial PLC I/O modules. IC Role / Device Role / Timing Role: Fast-switching clamp diode placed between signal line and VCC/GND rails to divert surge energy before logic gate breakdown. Use Value: 4 ns trr prevents latch-up propagation; 75 V VR rating accommodates 24 V system rail transients with safety margin. | Use Scenario: Sharpening slow-rise pulses from microcontroller GPIO outputs driving optocouplers in isolated feedback loops. IC Role / Device Role / Timing Role: Series-connected switching diode in RC differentiator network to generate clean positive/negative spikes. Use Value: Low Cd (≤4 pF) avoids pulse rounding; 225 mA IFRM supports brief 100 mA spike currents without degradation. |
| RF Signal Detection | Sample-and-Hold Input Buffering |
Use Scenario: Demodulating AM signals in low-power wireless sensor receiver front-ends operating at 1–10 MHz. IC Role / Device Role / Timing Role: Passive envelope detector diode rectifying RF carrier while preserving modulation fidelity. Use Value: 4 pF capacitance minimizes RF shunting; 25 nA IR at 20 V ensures low detection threshold and high sensitivity. | Use Scenario: Isolating analog multiplexer outputs from hold capacitor leakage in 12-bit data acquisition systems. IC Role / Device Role / Timing Role: Guard diode limiting voltage excursion during multiplexer channel switching to prevent capacitor discharge. Use Value: 0.62 V VF at 5 mA reduces offset error; 175 °C Tj rating allows stable operation near warm ADC components. |
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 |
|---|---|---|---|
| 1N4148,113 | Higher trr (4 ns typical but 8 ns max); identical VF and VRRM; same SOD27 package | Marginally slower in ultra-fast edge-sensitive designs; otherwise interchangeable in general-purpose switching | Select 1N4148,113 where cost or legacy BOM compatibility outweighs need for guaranteed 4 ns trr |
| BAS16,215 | Lower VF (0.85 V max at 50 mA); 6 ns trr typ; SOT23 surface-mount package | Requires PCB redesign for SMT; better for high-density layouts but unsuitable for through-hole prototyping | Choose BAS16,215 when board space is constrained and reflow assembly is available |
Compared with 1N914B,113, the 1N4148,113 offers broader availability but looser trr guarantee, while the BAS16,215 trades axial-leaded ease-of-use for compact SMT integration-neither is pin-compatible due to differing packages.

FAQ
What is the maximum reverse recovery time (trr) specification for the 1N914B,113?
The 1N914B,113 has a maximum reverse recovery time of 4 ns when switched from IF = 10 mA to IR = 60 mA, with RL = 100 Ω and measurement threshold at IR = 1 mA. This value is confirmed in the Philips (now NXP) 2003 datasheet and distinguishes it from earlier variants like the 1N914A, which specifies up to 8 ns under the same test conditions. The 1N914B,113 maintains this speed across its full rated temperature range.
Does the 1N914B,113 have a specified forward voltage at 100 mA?
Yes, the 1N914B,113 has a maximum forward voltage of 1.0 V at IF = 100 mA, as stated in the Electrical Characteristics table of the official datasheet. This parameter ensures predictable conduction behavior in moderate-current pulse applications such as optocoupler drive or transient clamping, complementing its tighter 0.62–0.72 V spec at 5 mA for low-level signal routing.
Is the 1N914B,113 RoHS compliant?
The 1N914B,113 was originally manufactured prior to mandatory RoHS implementation and is not certified RoHS compliant. It contains lead in the solder dip and glass encapsulant. For new designs requiring RoHS compliance, engineers should consider modern equivalents such as the PMLL4148L or BAS16,215, both of which meet current EU directives while offering comparable electrical performance.
What is the cathode identification method on the 1N914B,113 package?
The cathode of the 1N914B,113 is identified by a distinct colored band located near one end of the hermetically sealed glass SOD27 (DO-35) package. This marking aligns with JEDEC standard DO-35 orientation and must be oriented toward the more positive potential in forward-biased configurations. The anode is the unmarked lead, and polarity verification is critical for correct placement in clamping and rectification circuits.
Can the 1N914B,113 replace the 1N4148 in existing designs?
The 1N914B,113 can functionally replace the 1N4148 in many high-speed switching roles due to matching package (SOD27), voltage ratings (100 V VRRM), and similar VF, but its guaranteed 4 ns trr (vs. 8 ns max for 1N4148) makes it preferable in edge-critical applications. However, the 1N914B,113 is obsolete and no longer in active production, so long-term supply assurance favors the 1N4148,113 for new designs unless legacy qualification mandates the 1N914B,113.
