Product details
Overview
1.5KE62CA-E3/54 from Vishay General Semiconductor is a bidirectional 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, and operates across –55 °C to +175 °C. It is used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients in industrial and automotive systems.
For engineers reviewing the 1.5KE62CA-E3/54 datasheet, 1.5KE62CA-E3/54 pinout, 1.5KE62CA-E3/54 application, or 1.5KE62CA-E3/54 equivalent, this device delivers verified bidirectional clamping performance with glass-passivated junction reliability, AEC-Q101 qualification eligibility (HE3 variant), and RoHS-compliant matte tin leads - critical for high-reliability surge protection design and BOM continuity planning.
Technical Context
This TVS diode employs a silicon avalanche junction structure with glass passivation for stable breakdown characteristics and low incremental surge resistance. Its bidirectional configuration enables symmetrical clamping in AC-coupled or floating signal paths without polarity constraints.
It responds in <1 ns to transient events and maintains clamping integrity under repetitive 10/1000 µs pulses at 0.01% duty cycle. Thermal resistance is specified at RθJL = 15.4 °C/W (junction-to-lead), supporting direct PCB heat sinking via leads in high-power surge scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 58.9–65.1 V at 1.0 mA - defines precise clamping initiation threshold in both directions |
| Stand-off Voltage VWM | 53.0 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| Peak Pulse Power PPPM | 1500 W (10/1000 µs) - sustains single high-energy surges typical of lightning or load dump |
| Clamping Voltage VC | 85.0 V at 17.6 A IPPM - limits downstream voltage stress during full-rated surge current |
| Junction Temperature Range | –55 °C to +175 °C - supports operation in under-hood automotive and industrial environments |
| Package | Case Style 1.5KE - axial-leaded DO-201AD package with UL 94 V-0 molded epoxy body |
| Leakage Current ID | ≤1.0 µA at VWM - ensures minimal standby power loss in always-on circuits |
Pinout & Package
1.5KE62CA-E3/54 uses the standard DO-201AD (Case Style 1.5KE) axial-leaded package. Bidirectional construction means no cathode marking; both terminals are functionally identical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both ends serve as bidirectional avalanche junction terminals; no polarity orientation required on PCB |
| Lead 1 / Lead 2 | Thermal and electrical interface | Matte tin-plated leads provide solderability per J-STD-002 and support junction-to-lead thermal dissipation (RθJL = 15.4 °C/W) |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures long-term stability of VBR and low parameter drift over temperature and life |
| 1500 W peak pulse rating | Handles IEC 61000-4-5 Level 4 surge currents without degradation when properly mounted |
| Bidirectional symmetry | Eliminates need for polarity-aware layout in AC lines, telecom interfaces, or differential buses |
| AEC-Q101 qualification option | HE3 suffix variants meet automotive-grade reliability requirements for engine control and ADAS sensors |
| UL 94 V-0 flammability rating | Mold compound prevents flame propagation in safety-critical enclosures and industrial housings |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting CAN transceiver power rails and I/O lines against load dump and jump-start transients in 12 V vehicle systems. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between VCC and ground, responding within <1 ns to suppress >100 V spikes. Use Value: Limits voltage seen by 3.3 V/5 V CAN PHY to ≤85 V, preventing latch-up or gate oxide rupture in transceivers such as TJA1042. |
Use Scenario: Shielding 4–20 mA current loop inputs and RS-485 data lines in PLC analog modules from ESD and field wiring surges. IC Role / Device Role / Timing Role: Primary front-end surge shunt, installed before protection diodes and series resistors in signal conditioning circuitry. Use Value: Clamps induced transients up to 1500 W without forward conduction, preserving signal integrity and enabling Class III IEC 61000-4-5 compliance. |
| Telecom DSL Line Protection | Consumer Appliance Motor Drive Protection |
Use Scenario: Guarding ADSL/VDSL line drivers and transformers against lightning surges entering via outdoor copper pairs. IC Role / Device Role / Timing Role: Secondary-level protector located after gas discharge tube (GDT), absorbing residual energy after GDT fires. Use Value: Provides sub-100 ns response to fast-rising surges missed by slower GDTs, reducing let-through voltage to <85 V at full 17.6 A surge. |
Use Scenario: Safeguarding microcontroller GPIOs and gate drivers connected to brushed DC motor commutation circuits in washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Snubber-style clamp across motor terminals or driver supply rails to absorb inductive kickback. Use Value: Dissipates 1500 W peak energy from 100+ V flyback spikes, extending MCU lifetime and eliminating need for external RC snubbers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Lower peak power (600 W), smaller SMB package (surface-mount), lower clamping voltage (103 V at 5.8 A) | Better suited for space-constrained PCBs with moderate surge exposure (IEC 61000-4-2/4-4); not rated for 1500 W IEC 61000-4-5 Level 4 | Select when board area is limited and surge threat level is below 1 kA (8/20 µs); requires re-evaluation of thermal layout due to higher RθJA. |
| 1.5SMC68CA | Same 1500 W rating and DO-214AB package, but higher VBR (64.6–71.4 V) and clamping voltage (113 V at 13.3 A) | Used where higher stand-off margin is needed (e.g., 48 V industrial buses), but offers less precise clamping near 62 V nominal rails | Choose when system operating voltage exceeds 53 V and tighter VC tolerance is secondary to higher surge margin. |
Compared with SMBJ64CA and 1.5SMC68CA, the 1.5KE62CA-E3/54 uniquely balances 62 V precision clamping, 1500 W capability, and through-hole mechanical robustness - making it optimal for high-energy, high-reliability protection where leaded mounting and exact VWM/VBR alignment are design priorities.

FAQ
What is the breakdown voltage tolerance for 1.5KE62CA-E3/54?
The 1.5KE62CA-E3/54 has a specified breakdown voltage range of 58.9 V to 65.1 V at a test current of 1.0 mA. This ±5% tolerance ensures consistent clamping behavior across production lots and supports reliable overvoltage threshold design in 48–60 V systems where precise standoff is required.
Is 1.5KE62CA-E3/54 RoHS compliant and lead-free?
Yes, the "E3" suffix in 1.5KE62CA-E3/54 indicates full RoHS compliance per EU Directive 2011/65/EU, with matte tin-plated leads meeting J-STD-002 solderability standards and JESD 201 Class 1A whisker resistance. No lead content is present in the finish or molding compound.
Can 1.5KE62CA-E3/54 be used in automotive applications?
The base 1.5KE62CA-E3/54 is commercial-grade, but the HE3 variant (e.g., 1.5KE62CAHE3_B) is AEC-Q101 qualified for automotive use. For under-hood or ADAS applications, specify the HE3 version to ensure validated reliability under temperature cycling, humidity, and mechanical shock per automotive standards.
What is the maximum clamping voltage of 1.5KE62CA-E3/54 under full surge conditions?
At its rated peak pulse current of 17.6 A (10/1000 µs waveform), the 1.5KE62CA-E3/54 clamps to a maximum of 85.0 V. This value is guaranteed per datasheet testing and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
How does the bidirectional nature of 1.5KE62CA-E3/54 affect PCB layout?
The 1.5KE62CA-E3/54 has no polarity marking and functions identically in either orientation, simplifying layout for AC-coupled lines, transformer-isolated interfaces, or differential buses like RS-485. No silkscreen polarity indicator is needed, reducing assembly risk and enabling symmetric placement across split grounds or floating references.
