Product details
Overview
1.5KE62CAHE3/51 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 62 V breakdown voltage (VBR = 58.9–65.1 V at 1 mA), 1500 W peak pulse power (10/1000 µs), clamping voltage of 85.0 V at 17.6 A, AEC-Q101 qualification, and RoHS-compliant HE3 packaging - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5KE62CAHE3/51 datasheet, 1.5KE62CAHE3/51 pinout, 1.5KE62CAHE3/51 application, or 1.5KE62CAHE3/51 equivalent, this page delivers verified electrical parameters, JEDEC-standard 1.5KE package details, bi-directional clamping behavior, thermal derating curves, and direct alternative options for ESD/lightning surge protection design.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, with identical VBR, VC, and IPPM specifications in forward and reverse directions. Its glass-passivated junction enables sub-nanosecond response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 µs transients at 0.01% duty cycle.
The device is rated for TJ = –55 °C to +175 °C, exhibits ±0.104 %/°C temperature coefficient of VBR, and maintains 85.0 V clamping at 17.6 A peak pulse current - critical for protecting MOSFET gates and microcontroller I/O against ISO 7637-2 pulse 1/2a/5a and IEC 61000-4-5 surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1.0 mA - defines reliable conduction onset for bidirectional overvoltage events |
| VC @ IPPM | 85.0 V at 17.6 A - maximum clamped voltage during 1500 W transient, limiting stress on downstream ICs |
| PPPM | 1500 W (10/1000 µs waveform) - sustains high-energy lightning-induced surges without failure |
| VWM | 53.0 V - maximum working voltage before leakage exceeds 1.0 µA, ensuring no false triggering in 48 V systems |
| TJ max. | +175 °C - supports operation in under-hood automotive environments and high-ambient industrial enclosures |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| RθJL | 15.4 °C/W - enables effective heat dissipation through PCB copper pour or lead-frame conduction |
Pinout & Package
1.5KE62CAHE3/51 uses the standard axial-leaded Case Style 1.5KE package (JEDEC DO-201AD), with no polarity marking - consistent with bi-directional functionality. Leads are matte tin-plated, solderable per J-STD-002/JESD 22-B102, and qualified to JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (unmarked) | Bi-directional transient conduction path | Identical clamping in both directions; no cathode band - simplifies layout and eliminates polarity error risk |
| Lead 1 / Lead 2 | Thermal and electrical interface | Each lead conducts full surge current and transfers heat; requires ≥0.375" (9.5 mm) lead length for rated PD = 6.5 W |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables <1 ns response time and stable leakage (<1 µA at VWM) across –55 °C to +175 °C |
| 1500 W peak pulse power (10/1000 µs) | Withstands IEC 61000-4-5 Level 4 (4 kV line-earth, 2 kV line-line) surges without degradation |
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics per stress test requirements (HTRB, TC, AC/DC life) |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability for safety-critical assemblies |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes let-through energy to protected ICs - critical for 3.3 V/5 V logic and CAN transceivers |
Applications
| Automotive Sensor Interface Protection | Industrial PLC Analog Input Protection |
|---|---|
|
Use Scenario: Protecting LIN/CAN bus nodes and temperature/pressure sensors exposed to load dump and inductive switching noise in vehicle ECUs. IC Role / Device Role / Timing Role: Bi-directional clamping element placed across signal/power pins to shunt transients before they reach MCU GPIO or analog front-end. Use Value: Clamps 85.0 V at 17.6 A while maintaining 53.0 V stand-off - enabling direct integration into 12 V/24 V sensor harnesses without series impedance. |
Use Scenario: Safeguarding 4–20 mA current loop inputs and ±10 V analog channels in programmable logic controllers against field wiring surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on terminal blocks and input conditioning stages, operating symmetrically for AC-coupled or floating signals. Use Value: Sub-nanosecond response ensures clamping occurs before op-amp input stages saturate or ESD structures fail - preserving measurement integrity. |
| Telecom Line Card Surge Protection | Consumer Power Adapter Output Protection |
|
Use Scenario: Secondary protection on DSL/VDSL line cards where primary GDTs handle bulk energy and TVS limits residual overshoot. IC Role / Device Role / Timing Role: Fast-acting secondary suppressor bridging tip/ring lines to ground, coordinated with upstream gas discharge tubes. Use Value: 1500 W rating and 85.0 V clamping enable coordination with 90 V GDTs to meet GR-1089-CORE Level 3 immunity without sacrificing bandwidth. |
Use Scenario: Output-side transient suppression in wall-mounted AC/DC adapters for USB-C PD and smart home hubs. IC Role / Device Role / Timing Role: Final-stage clamp on regulated DC output rails (5 V/9 V/12 V) to prevent latch-up in connected devices during hot-plug events. Use Value: AEC-Q101 qualification and 175 °C TJ max ensure reliability in sealed, thermally constrained enclosures with no airflow. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ64CA | 64 V VBR (min 60.8 V), 400 W PPPM, SMA package (surface-mount), RθJA = 110 °C/W | Lower power handling; suited for PCB space-constrained designs where 1500 W is not required | Select when board area is limited and surge threat level is IEC 61000-4-5 Level 2 (1 kV differential) |
| ON Semiconductor 1.5SMC64CA | 64 V VBR (min 60.8 V), 1500 W PPPM, SMC package (surface-mount), RθJL = 12.5 °C/W | Same power rating but SMC footprint - requires rework of through-hole layout and thermal pad design | Choose for automated assembly and higher thermal performance if redesigning PCB for surface-mount |
Compared with 1.5KE62CAHE3/51, SMAJ64CA offers compactness at reduced surge capacity, while 1.5SMC64CA matches power rating but demands SMT layout changes - making 1.5KE62CAHE3/51 optimal for legacy through-hole designs requiring automotive-grade reliability and proven 1500 W capability.

FAQ
What is the breakdown voltage tolerance for 1.5KE62CAHE3/51?
The 1.5KE62CAHE3/51 has a specified breakdown voltage range of 58.9 V to 65.1 V at 1.0 mA test current, representing ±5% tolerance around the nominal 62 V rating. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes from –55 °C to +175 °C.
Is 1.5KE62CAHE3/51 suitable for automotive applications?
Yes, 1.5KE62CAHE3/51 is AEC-Q101 qualified and explicitly listed in Vishay's documentation for automotive use. Its construction - including glass-passivated junction, HE3 whisker-resistant leads, and operation up to +175 °C - meets requirements for engine control units, body electronics, and ADAS sensor interfaces subjected to load dump and ISO 7637-2 pulses.
How does the bi-directional nature of 1.5KE62CAHE3/51 affect circuit placement?
Because 1.5KE62CAHE3/51 is bi-directional and unmarked, it can be installed in either orientation across protected lines - eliminating polarity errors during manual assembly or wave soldering. This simplifies layout for AC-coupled signals, differential buses (e.g., RS-485), and floating power domains where voltage reversal may occur.
What is the maximum clamping voltage of 1.5KE62CAHE3/51 under surge conditions?
The 1.5KE62CAHE3/51 clamps to a maximum of 85.0 V when subjected to its rated 17.6 A peak pulse current (10/1000 µs waveform). This VC value is guaranteed across temperature and lifetime, providing a known upper bound for protected circuit stress during lightning or inductive switching events.
Can 1.5KE62CAHE3/51 replace uni-directional TVS diodes like 1.5KE62AHE3/51?
No - 1.5KE62CAHE3/51 is strictly bi-directional and lacks polarity marking, whereas 1.5KE62AHE3/51 is uni-directional with a cathode band. Substituting them requires verifying that the application tolerates conduction in both directions; using 1.5KE62CAHE3/51 in place of a uni-directional part may cause unintended forward conduction during normal operation.
