Product details
Overview
1N4607 from BKC is a silicon switching diode in DO-35 glass package, rated for 85 V peak inverse voltage, 200 mA average rectified current, and 10 ns reverse recovery time-enabling fast switching in signal routing and low-power DC-DC converter flyback paths.
For engineers reviewing the 1N4607 datasheet, 1N4607 pinout, 1N4607 application, or 1N4607 equivalent, key selection criteria include its 85 V PIV rating, sub-1.1 V forward drop at 400 mA, 100 µA max reverse leakage at 50 V, DO-35 mechanical dimensions, and -65°C to +200°C operating range.
Technical Context
The 1N4607 is a planar-diffused, metallurgically bonded silicon PN junction diode optimized for high-speed switching in low-current signal and timing circuits. Its 10 ns reverse recovery time and controlled forward voltage profile support clean edge transitions in pulse shaping and clamp applications.
Designed for operation up to +200°C with 500 mW power dissipation at TL = 50°C (lead length 3/8″), the device uses BKC's Sigma Bond™ plating for reliable solderability and maintains stable PIV ≥85 V under 5 µA leakage test conditions down to -55°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Inverse Voltage | 85 V minimum - ensures blocking capability in 48 V and lower DC supply rails with margin |
| Average Rectified Current | 200 mA - supports continuous conduction in low-power signal demodulation and logic-level clamping |
| Reverse Recovery Time | 10 ns - enables reliable operation in >10 MHz switching circuits without tail current distortion |
| Forward Voltage @ 400 mA | ≤1.10 V - limits power loss to <440 mW during transient conduction bursts |
| Reverse Leakage @ 50 V | ≤100 µA - maintains signal integrity in high-impedance bias and sample-hold nodes |
| Operating Temperature Range | -65°C to +200°C - qualified for under-hood automotive, aerospace, and industrial sensor front-ends |
Pinout & Package
DO-35 glass axial package: cylindrical body (Ø 1.6–1.7 mm × L 3.30–3.70 mm), tinned copper leads (Ø 0.41–0.55 mm), hermetically sealed, lead-free compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry node | Connected to lower-potential side in rectifier/clamp; requires PCB trace capable of 200 mA continuous |
| Cathode | Forward current exit node / PIV reference | Marked with band; ties to higher-potential rail or switching node; must withstand 85 V transient reversals |
Key Features
| Feature | Design Value |
|---|---|
| Six Sigma quality manufacturing | Statistical process control ensures ≤3.4 defects per million units-critical for automotive and medical BOMs |
| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal cycling, supporting 1000+ cycles at ΔT = 150°C |
| Sigma Bond™ plating | Guarantees void-free solder wetting on ENIG, HASL, and immersion silver PCB finishes without flux additives |
| Fast 10 ns trr | Reduces switching losses by >60% vs. general-purpose 1N4148 in 5–20 MHz clock distribution networks |
Applications
| High-Speed Signal Clamping | Precision Timing Reference Clamp |
|---|---|
Use Scenario: Protecting ADC input stages from ESD-induced overvoltage transients in portable instrumentation. IC Role / Device Role / Timing Role: Fast-acting voltage limiter that conducts within 10 ns to clamp spikes to ≤1.1 V above rail. Use Value: Prevents latch-up in 12-bit SAR ADCs while adding <0.5 pF parasitic capacitance to the signal path. |
Use Scenario: Stabilizing oscillator node voltage in crystal-based real-time clock (RTC) circuits. IC Role / Device Role / Timing Role: Low-leakage (<100 µA) clamp diode maintaining precise bias point across temperature. Use Value: Enables ±2 ppm frequency stability over -40°C to +85°C by minimizing bias drift in Pierce gate. |

IC Role / Device Role / Timing Role: Fast-recovery snubber diode conducting only during MOSFET turn-off edge. Use Value: Limits drain overshoot to <90 V with 10 ns response-reducing need for TVS and lowering EMI filter size. |
Use Scenario: Bidirectional level shifting between 3.3 V microcontroller GPIOs and 5 V legacy peripherals. IC Role / Device Role / Timing Role: Passive clamping diode enabling safe 0–3.3 V ↔ 0–5 V signal translation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4148WS | Same DO-35 package; 100 V PIV, 150 mA Iavg, 4 ns trr, but rated only to +150°C | Better speed for >25 MHz RF detector use; reduced thermal margin in engine-control modules | Select when trr < 4 ns is required and ambient stays below +150°C |
| LL4148 | LL-34 (DO-213AA) surface-mount package; identical 100 V/150 mA/4 ns specs; no axial leads | Enables automated SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select for volume production where reflow compatibility and board space savings outweigh manual assembly needs |
Compared with 1N4607, the 1N4148WS offers faster switching but sacrifices high-temperature reliability, while the LL4148 provides identical electrical performance in a surface-mount form-making the 1N4607 optimal for ruggedized through-hole designs requiring +200°C operation.

FAQ
What is the maximum continuous forward current rating for the 1N4607?
The 1N4607 has a continuous forward current (IFdc) rating of 200 mA at TL = 50°C with 3/8″ lead length. This rating assumes adequate PCB copper pour and ambient airflow; derating is required above 50°C lead temperature or with shorter leads.
Does the 1N4607 meet automotive AEC-Q101 requirements?
The 1N4607 is not AEC-Q101 qualified per published BKC documentation. While it operates from -65°C to +200°C and uses metallurgical bonding, formal stress testing per AEC-Q101-including HTGB, HTRB, and temperature cycling-is not documented for this specific 1N4607 lot release.
What is the reverse recovery time measurement condition for the 1N4607?
The 10 ns reverse recovery time (trr) for the 1N4607 is measured per Method 4031-A: IF = 10 mA, VR = 6 V, RL = 100 Ω. This standardized test confirms consistent switching behavior across production lots.
Can the 1N4607 replace the 1N4148 in all applications?
The 1N4607 can replace the 1N4148 where 85 V PIV and +200°C operation are needed-but not where 4 ns trr or 300 mA IFdc are required. The 1N4607's 10 ns trr and 200 mA rating make it unsuitable for >25 MHz RF detector or high-current logic clamp roles defined for 1N4148.
Is the 1N4607 available in tape-and-reel packaging for automated assembly?
Yes, the 1N4607 is offered in tape-and-reel format (EIA-481 compliant) with 2,000 pieces per reel. Reel packaging includes moisture-sensitive level (MSL) 1 handling and is compatible with standard pick-and-place equipment for axial-component feeders.
