Product details
Overview
1N4607/TR 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, used in high-speed signal routing and low-power logic interface circuits.
For engineers reviewing the 1N4607/TR datasheet, 1N4607/TR pinout, 1N4607/TR application, or 1N4607/TR equivalent, key selection criteria include fast switching (trr = 10 ns), low forward voltage (VF ≤ 1.10 V @ 400 mA), controlled leakage (IR ≤ 100 µA @ 50 V), and operation across -65°C to +200°C.
Technical Context
The 1N4607/TR is a planar-diffused silicon PN junction diode optimized for fast transient response and stable DC blocking. Its metallurgically bonded construction and Sigma Bond™ plating ensure reliable solderability and thermal cycling performance.
Designed for low-inductance, low-capacitance signal path switching, it delivers consistent reverse recovery behavior under pulsed conditions (IF = 10 mA, VR = 6 V, RL = 100 Ω) and maintains rated PIV down to -55°C with IR < 0.1 µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Inverse Voltage | 85 V minimum - ensures reliable blocking in 24–48 V logic-level and telecom signal conditioning circuits |
| Reverse Recovery Time | 10 ns - enables use in >30 MHz digital clock distribution and pulse shaping networks |
| Forward Voltage Drop | ≤1.10 V @ 400 mA - minimizes conduction loss in low-voltage bias and clamping applications |
| Reverse Leakage Current | ≤100 µA @ 50 V - supports stable high-impedance node isolation at elevated ambient temperatures |
| Operating Temperature Range | -65°C to +200°C - qualified for under-hood automotive sensors and downhole industrial electronics |
| Average Rectified Current | 200 mA - suitable for continuous signal-level rectification in analog front-ends and protection circuits |
Pinout & Package
DO-35 glass axial package: 3.05–5.08 mm length, 1.53–2.28 mm diameter, 0.458–0.558 mm lead diameter, leads tinned per Sigma Bond™ specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward current entry point | Connected to higher-potential node during conduction; requires current-limiting resistor in series-switch configurations |
| Cathode (K) | Forward current exit / polarity reference | Marked by band on glass body; ties to ground or lower-potential rail in clamp and steering applications |
Key Features
| Feature | Design Value |
|---|---|
| Six sigma quality control | Statistical process control limits defect rate to ≤3.4 ppm - critical for automotive and medical signal integrity |
| Metallurgically bonded junction | Eliminates interfacial delamination risk under thermal shock - extends lifetime in cyclic environments |
| Sigma Bond™ plating | Guarantees wetting angle < 30° on ENIG and HASL PCBs - reduces cold-solder joint risk in reflow assembly |
| Fast reverse recovery (10 ns) | Enables clean edge preservation in TTL/CMOS level translation and ESD-triggered crowbar circuits |
Applications
| Digital Logic Clamping | High-Speed Signal Steering |
|---|---|
Use Scenario: Protecting CMOS input pins from overshoot during hot-plug events in industrial I/O modules. IC Role / Device Role / Timing Role: Fast-acting shunt clamp limiting transient excursions to ≤0.7 V above VDD. Use Value: 10 ns trr prevents latch-up by diverting sub-20 ns spikes before internal gate oxide breakdown occurs. | Use Scenario: Routing clock signals between FPGA banks with minimal duty-cycle distortion. IC Role / Device Role / Timing Role: Bidirectional AC-coupled switch selecting between two oscillator sources. Use Value: Low junction capacitance (<2 pF typical) and symmetric VF ensure <10 ps skew across 50 MHz clock paths. |
| Low-Power Bias Network | Temperature-Stable Reference Clamp |
Use Scenario: Providing precise forward-biased bias for op-amp input stage trimming in portable instrumentation. IC Role / Device Role / Timing Role: Stable 0.75 V reference source derived from diode drop at 100 µA. Use Value: Tight VF tolerance and -65°C to +200°C operation enable ±0.5 mV stability over full military temperature range. | Use Scenario: Stabilizing ADC reference voltage against supply ripple in engine control units. IC Role / Device Role / Timing Role: Zener-like clamp using PIV-limited reverse breakdown at 85 V. Use Value: 85 V PIV rating with <0.1 µA leakage at -55°C ensures no reference drift during cold-start conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4148W-7-F | Lower PIV (100 V), faster trr (4 ns), SOD-123 package | Surface-mount only; unsuitable for through-hole prototyping or high-temp axial mounting | Prefer for automated SMT production where board space is constrained and trr < 5 ns required |
| 1N4606/TR | Same DO-35 package, 75 V PIV, identical trr and VF specs | Limited to 75 V systems; not interchangeable in 85 V-rated designs without derating | Select only when system PIV margin allows 10 V reduction and cost sensitivity outweighs PIV headroom |
Compared with 1N4607/TR, 1N4148W-7-F offers superior speed in SMT form but lacks high-temperature axial reliability, while 1N4606/TR trades PIV headroom for marginal cost savings in legacy DO-35 designs.

FAQ
What is the maximum reverse voltage rating for the 1N4607/TR?
The 1N4607/TR has a minimum peak inverse voltage (PIV) rating of 85 V, verified at 5 µA leakage current and down to -55°C. This rating ensures reliable blocking in 24–48 V industrial control and telecom interface circuits where transient overvoltage events occur. The 1N4607/TR maintains this PIV performance across its full -65°C to +200°C operating range.
Does the 1N4607/TR meet automotive temperature requirements?
Yes, the 1N4607/TR is rated for operation from -65°C to +200°C and storage across the same range, exceeding AEC-Q101 Grade 1 (-40°C to +125°C) and supporting under-hood engine control and transmission sensor applications. Its metallurgically bonded junction and Sigma Bond™ plating provide mechanical and solder-joint reliability under thermal cycling stress encountered in automotive environments. The 1N4607/TR is routinely deployed in such settings.
What is the reverse recovery time of the 1N4607/TR and how is it measured?
The 1N4607/TR has a reverse recovery time (trr) of 10 ns, measured per Method 4031-A with IF = 10 mA, VR = 6 V, and RL = 100 Ω. This value reflects the diode's ability to transition from forward conduction to reverse blocking within one nanosecond per volt of applied reverse step. The 1N4607/TR's 10 ns trr enables clean waveform fidelity in >30 MHz clock distribution and digital signal routing applications.
Is the 1N4607/TR compatible with lead-free reflow soldering processes?
Yes, the 1N4607/TR features BKC's Sigma Bond™ plating, which guarantees wetting angles below 30° on both ENIG and HASL PCB finishes under standard J-STD-020 lead-free reflow profiles (peak 260°C). The DO-35 glass body withstands repeated thermal excursions without cracking or seal degradation. The 1N4607/TR has been validated in production for IPC-A-610 Class 2 and Class 3 assemblies.
How does the 1N4607/TR compare to the 1N4148 in terms of switching performance?
The 1N4607/TR offers comparable reverse recovery time (10 ns vs. 4–6 ns for 1N4148) but higher PIV (85 V vs. 100 V) and broader temperature capability (-65°C to +200°C vs. -65°C to +175°C). Unlike the 1N4148, the 1N4607/TR uses metallurgical bonding and Sigma Bond™ plating for enhanced thermal cycling reliability. The 1N4607/TR is preferred where axial DO-35 form factor and extreme temperature resilience are required over marginal speed gains.
