Product details
Overview
1.5KE10C-E3/73 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal and power lines. It features a 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage at 10 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and operates across –55 °C to +175 °C junction temperature. It protects MOSFETs and ICs in automotive sensor interfaces against inductive switching surges.
For engineers reviewing the 1.5KE10C-E3/73 datasheet, 1.5KE10C-E3/73 pinout, 1.5KE10C-E3/73 application, or 1.5KE10C-E3/73 equivalent, this page delivers verified electrical parameters, polarity marking guidance, thermal resistance data, clamping behavior under standardized surge waveforms, and direct alternatives with documented differences in breakdown voltage tolerance and unidirectional/bidirectional configuration.
Technical Context
This device uses a glass passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating signal paths without polarity sensitivity.
It complies with JEDEC standards for transient suppression and supports repetitive surge duty cycles up to 0.01 % at TA = 25 °C. The 1.5KE package provides 75 °C/W junction-to-ambient thermal resistance and is rated for 200 A non-repetitive forward surge (unidirectional only - not applicable to 1.5KE10C-E3/73 due to bidirectional polarity).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR min / max | 9.5 V / 10.5 V - Breakdown occurs within this range at 1 mA test current; ensures predictable clamping onset. |
| VC @ IPPM | 14.5 V - Clamped voltage at 10 A peak pulse current (10/1000 µs); determines protected circuit's maximum overvoltage exposure. |
| PPPM | 1500 W - Peak pulse power handling capability; defines survivability against lightning-induced or inductive-switching transients. |
| IPPM | 10 A - Peak pulse current corresponding to VC = 14.5 V; used to size series impedance for current limiting. |
| TJ max | +175 °C - Maximum junction temperature; supports operation in under-hood automotive or industrial environments. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; informs heatsinking requirements for sustained surge events. |
Pinout & Package
1.5KE10C-E3/73 uses the industry-standard Case Style 1.5KE DO-201AD axial-leaded package. Bidirectional construction means no cathode marking; both leads are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Either lead serves as input/output for bidirectional clamping; no polarity orientation required during PCB placement. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable long-term reliability and consistent VBR performance across temperature and life cycle. |
| 1500 W peak pulse power (10/1000 µs) | Supports robust protection against IEC 61000-4-5 Level 4 surges (4 kV line-earth) when combined with appropriate series impedance. |
| Clamping time < 1 ns | Responds faster than MOVs or GDTs, preventing voltage overshoot that could damage sub-20 V logic or analog front-ends. |
| RoHS-compliant, commercial grade (E3 suffix) | Meets JESD 201 Class 1A whisker resistance and J-STD-002 solderability standards for high-volume manufacturing. |
Applications
| Automotive Sensor Interface Protection | Industrial RS-485 Data Line Clamp |
|---|---|
Use Scenario: Protecting LIN/CAN transceiver inputs and analog sensor outputs (e.g., pressure, temperature) from load-dump and inductive kickback in 12 V vehicle systems. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector entry point to shunt transients before reaching ESD-hardened IC pins. Use Value: Limits voltage excursion to ≤14.5 V during 10 A transients, preserving integrity of 5 V or 3.3 V supply rails and ADC reference inputs. |
Use Scenario: Guarding differential RS-485 bus lines (A/B) against EFT bursts and lightning-induced common-mode surges in factory automation networks. IC Role / Device Role / Timing Role: Paired 1.5KE10C-E3/73 devices (line-to-ground) provide symmetrical clamping without disrupting DC bias or signal integrity. Use Value: Maintains <15 V differential swing during surge events, ensuring receiver threshold margins remain intact per TIA-485-A. |
| Consumer Appliance Motor Drive Snubbing | Telecom DSL Line Surge Suppression |
Use Scenario: Suppressing back-EMF spikes from brushed DC motors in washing machines or HVAC blowers connected to microcontroller GPIOs. IC Role / Device Role / Timing Role: Mounted across motor terminals or between driver output and ground to clamp bidirectional inductive spikes. Use Value: Absorbs 1500 W pulses without degradation, eliminating need for external snubber RC networks and reducing BOM count. |
Use Scenario: Protecting ADSL/VDSL line interface ICs from induced surges on twisted-pair telephone lines exposed to outdoor environments. IC Role / Device Role / Timing Role: Installed on each line (tip/ring) referenced to chassis ground in telecom demarcation boxes. Use Value: Withstands repeated 10/1000 µs surges up to 10 A while maintaining <1 pF junction capacitance impact on high-frequency DSL signals. |
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 package; lower PPPM (600 W); tighter VBR tolerance (9.4–10.6 V); higher VC (17.0 V @ 34.7 A) | Smaller footprint but reduced surge capacity; better suited for space-constrained consumer electronics vs. industrial-grade clamping. | Select SMBJ10CA when board area is critical and surge energy is limited to IEC 61000-4-5 Level 2. |
| 1.5KE10A-E3/73 | Unidirectional version; identical VWM, VBR, and VC; requires correct cathode orientation; includes 200 A IFSM rating. | Applicable only where DC bias exists and polarity is fixed (e.g., DC power rail protection), not for AC or floating signals. | Choose 1.5KE10A-E3/73 for 12 V supply rail clamping with known polarity; avoid in bidirectional signal paths. |
Compared with 1.5KE10C-E3/73, SMBJ10CA trades surge robustness for compactness, while 1.5KE10A-E3/73 adds unidirectional surge handling capability but eliminates polarity-agnostic installation - making 1.5KE10C-E3/73 the optimal choice for floating, AC-coupled, or polarity-unknown interfaces requiring full 1500 W protection.

FAQ
What is the standoff voltage rating of the 1.5KE10C-E3/73?
The 1.5KE10C-E3/73 has a maximum standoff voltage (VWM) of 10 V, meaning it remains non-conductive up to this DC or RMS voltage level. This value ensures compatibility with 5 V and 12 V systems while providing sufficient margin below its 9.5–10.5 V breakdown range. Exceeding 10 V continuously risks leakage current increase and premature clamping.
Is the 1.5KE10C-E3/73 RoHS compliant and lead-free?
Yes, the 1.5KE10C-E3/73 carries the "E3" suffix, indicating full RoHS compliance per Directive 2011/65/EU and exemption 7a. Its matte tin-plated leads meet J-STD-002 solderability and JESD 201 Class 1A whisker resistance requirements, supporting lead-free reflow and wave soldering processes without contamination risk.
How does the 1.5KE10C-E3/73 differ from the unidirectional 1.5KE10A-E3/73?
The 1.5KE10C-E3/73 is bidirectional with symmetrical clamping in both polarities and no cathode marking, whereas the 1.5KE10A-E3/73 is unidirectional, requires correct cathode orientation, and supports 200 A non-repetitive forward surge current. Their VWM, VBR, and VC values are identical, but polarity constraints make them non-interchangeable without circuit review.
What is the maximum clamping voltage of the 1.5KE10C-E3/73 under surge conditions?
The 1.5KE10C-E3/73 clamps to a maximum of 14.5 V when subjected to a 10 A peak pulse current with a 10/1000 µs waveform. This value is measured per JEDEC standard and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Can the 1.5KE10C-E3/73 be used in automotive applications?
Yes, the 1.5KE10C-E3/73 operates from –55 °C to +175 °C and meets AEC-Q101 qualification when ordered with the HE3 suffix (e.g., 1.5KE10CHE3_B). While the E3/73 variant is commercial grade, its thermal and surge performance aligns with under-hood and body-control module requirements when validated per system-level EMC testing.
