Product details
Overview
ICTE10C/1 from Vishay Semiconductors is a bidirectional Transient Voltage Suppressor (TVS) diode in Case Style 1.5KE package, rated for 10 V stand-off voltage, 1500 W peak pulse power (10/1000 µs), and clamps to ≤14.5 V at 10 A peak pulse current. It operates from –55 °C to +175 °C and is used for ESD and surge protection on bidirectional data lines such as RS-485, CAN bus, and industrial I/O interfaces.
For engineers reviewing the ICTE10C/1 datasheet, ICTE10C/1 pinout, ICTE10C/1 application, or ICTE10C/1 equivalent, key selection criteria include its bidirectional polarity, 10 V VWM, JEDEC-registered breakdown voltage of 11.7 V (min), low clamping ratio (1.24 at 10 A), and compatibility with high-temperature soldering (265 °C/10 s).
Technical Context
This device implements a glass-passivated, axial-leaded silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping above and below ground without external polarity constraints.
Designed per JEDEC standards, ICTE10C/1 delivers stable clamping performance across ambient temperatures up to +175 °C and supports repetitive surge events at ≤0.05% duty cycle. It meets UL 94V-0 flammability requirements and is rated for 200 A non-repetitive forward surge (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 10.0 V - Maximum continuous reverse voltage before clamping begins; defines operating window for protected line. |
| Breakdown Voltage (VBR) | 11.7 V min - Measured at 1.0 mA; ensures reliable turn-on during transients exceeding VWM. |
| Clamping Voltage (VC) | 14.5 V max at 10 A - Peak voltage seen by downstream circuitry during full-rated 1500 W surge. |
| Peak Pulse Power | 1500 W - Sustained for 10/1000 µs waveform; determines survivability against IEC 61000-4-5 Level 4 surges. |
| Reverse Leakage (ID) | 2.0 µA max at VWM - Minimal quiescent loading on signal lines; preserves signal integrity in low-power systems. |
| Junction Temperature Range | –55 °C to +175 °C - Enables deployment in under-hood automotive, industrial motor drives, and outdoor telecom equipment. |
Pinout & Package
Case Style 1.5KE: axial-leaded, molded plastic body with glass-passivated junction; polarity not applicable for bidirectional operation (symmetrical terminals).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Surge current path | Either lead conducts during positive or negative transients; no fixed polarity required in PCB layout. |
| Lead 1 | Terminal | Solderable per MIL-STD-750 Method 2026; supports 265 °C / 10 s high-temp reflow or hand-soldering. |
| Lead 2 | Terminal | Plated axial lead; mechanical mounting allows any orientation; weight 1.2 g. |
Key Features
| Feature | Design Value |
|---|---|
| UL 94V-0 certified package | Meets flame-retardant safety requirement for enclosed industrial and transportation enclosures. |
| 1500 W peak pulse rating (10/1000 µs) | Withstands IEC 61000-4-5 combination wave surges up to 4 kV open-circuit / 2 kA short-circuit. |
| Clamping factor 1.24 at full power | Ensures tight voltage margin between VWM and VC, reducing overvoltage stress on downstream ICs. |
| Low incremental surge resistance | Minimizes VC rise under high-current transients, improving protection margin for 3.3 V and 5 V logic rails. |
Applications
| Industrial RS-485 Networks | Automotive CAN Bus Interfaces |
|---|---|
Use Scenario: Protecting half-duplex differential bus lines in factory automation PLCs exposed to inductive switching noise and lightning-induced surges. IC Role / Device Role / Timing Role: Bidirectional TVS placed across A/B lines to clamp common-mode and differential transients before they reach the transceiver. Use Value: Maintains signal integrity under ±15 kV ESD (IEC 61000-4-2) and 2 kA surge (IEC 61000-4-5), preventing transceiver latch-up or damage. | Use Scenario: Safeguarding CAN H/L lines in engine control units subject to load dump and alternator ripple. IC Role / Device Role / Timing Role: Primary surge suppression element mounted at connector entry point, shunting energy away from CAN controller and PHY. Use Value: Clamps to ≤14.5 V at 10 A while surviving 175 °C junction temperature-critical for under-hood placement near powertrain modules. |
| Smart Meter Communication Ports | Outdoor Telecom Data Links |
Use Scenario: Securing optical isolator-coupled UART or M-Bus interfaces in utility meters installed in ungrounded outdoor cabinets. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing induced surges from nearby AC mains or lightning coupling into metering infrastructure. Use Value: 10 V VWM aligns with 12 V auxiliary supply rails; low leakage (≤2 µA) avoids battery drain in battery-backed meters. | Use Scenario: Protecting Ethernet-over-coax or DSL line drivers in remote base station cabinets exposed to atmospheric surges. IC Role / Device Role / Timing Role: First-stage protector on bidirectional analog/digital signal paths where polarity reversal may occur during fault conditions. Use Value: Symmetrical clamping eliminates need for dual unidirectional devices, simplifying BOM and PCB layout for field-deployed telecom gear. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | DO-214AA (SMB) package; 1000 W rating; 14.5 V clamping at 10 A; same VWM/VBR specs. | Surface-mount only; unsuitable for through-hole or high-vibration mechanical mounting. | Select SMBJ10CA when board space is constrained and reflow assembly is used; ICTE10C/1 preferred for axial-leaded reliability in industrial connectors. |
| 1N6383 | Same electrical specs and Case Style 1.5KE; identical JEDEC registration; manufactured by Vishay as direct part number alias. | No functional or mechanical difference; dual-marking for legacy catalog continuity. | 1N6383 is functionally identical to ICTE10C/1 and interchangeable without design change. |
Compared with SMBJ10CA and 1N6383, ICTE10C/1 offers axial-leaded mechanical robustness for high-vibration environments and legacy compatibility with 1.5KE footprint tooling, while maintaining identical clamping performance and thermal range as its surface-mount and legacy-bin counterparts.

FAQ
What is the maximum clamping voltage of ICTE10C/1 at 10 A peak pulse current?
The maximum clamping voltage of ICTE10C/1 is 14.5 V when subjected to a 10 A peak pulse current with a 10/1000 µs waveform. This value is specified in Table 2 of Vishay Document 88356 and reflects worst-case voltage seen by protected circuitry during full-rated surge events. ICTE10C/1 maintains this clamping performance across its full operating temperature range.
Is ICTE10C/1 unidirectional or bidirectional, and how is polarity identified?
ICTE10C/1 is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative transients without defined anode/cathode polarity. Unlike unidirectional types, it has no color band or polarity marking-either axial lead functions identically. This makes ICTE10C/1 ideal for AC-coupled or polarity-agnostic signal lines like CAN or RS-485.
What is the junction temperature range for ICTE10C/1, and why does it matter for automotive use?
ICTE10C/1 operates from –55 °C to +175 °C junction temperature, validated per JEDEC test conditions. This extended range enables direct placement near heat sources such as engine control units or power inverters, where ambient temperatures exceed 125 °C. The 175 °C rating ensures sustained reliability under under-hood thermal cycling-critical for ICTE10C/1 deployment in automotive CAN bus protection.
Can ICTE10C/1 replace 1N6383 in existing designs?
Yes, ICTE10C/1 is a direct replacement for 1N6383: both share identical electrical specifications, Case Style 1.5KE packaging, axial leads, and JEDEC registration. Vishay documents them as dual-marked variants in Document 88356. No PCB or schematic changes are needed when substituting ICTE10C/1 for 1N6383 in legacy or new designs.
What soldering conditions are guaranteed for ICTE10C/1?
ICTE10C/1 is qualified for high-temperature soldering at 265 °C for 10 seconds with 0.375" (9.5 mm) lead length under 5 lbs. (2.3 kg) tension, per Vishay specification. This ensures mechanical and electrical integrity during wave soldering, selective soldering, or hand-soldering processes-essential for ICTE10C/1 integration into industrial and automotive production lines.
