Product details
Overview
1.5KE62CAHE3_B/C 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), 1500 W peak pulse power (10/1000 µs), clamping voltage of 85.0 V at 17.6 A, 1.0 µA max reverse leakage at 53.0 V, and operates from –55 °C to +175 °C - deployed in automotive sensor interfaces and industrial I/O protection circuits.
For engineers reviewing the 1.5KE62CAHE3_B/C datasheet, 1.5KE62CAHE3_B/C pinout, 1.5KE62CAHE3_B/C application, or 1.5KE62CAHE3_B/C equivalent, this page delivers verified electrical specs, JEDEC 1.5KE package details, bidirectional clamping behavior, thermal derating curves, and AEC-Q101-qualified alternatives for ESD/lightning surge protection design validation.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time (<1 ns) and low incremental surge resistance. Its symmetrical clamping characteristic ensures identical forward and reverse conduction above VBR, enabling direct placement across AC-coupled or floating signal paths without polarity concerns.
The device complies with JEDEC standard 1.5KE case style, supports 10/1000 µs waveform testing per R.E.A., and exhibits a temperature coefficient of +0.104 %/°C for VBR. It is rated for 1500 W non-repetitive peak pulse power and derates linearly above 25 °C ambient using a 75 °C/W junction-to-ambient thermal resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V - guaranteed clamping onset range at 1.0 mA test current; defines minimum overvoltage threshold before conduction begins |
| VWM | 53.0 V - maximum continuous working voltage; circuit must operate ≤53.0 V DC or RMS to avoid leakage or degradation |
| IPPM | 17.6 A - peak pulse current at 10/1000 µs waveform; determines minimum series impedance needed to limit surge energy into protected IC |
| VC @ IPPM | 85.0 V - clamped voltage during 17.6 A transient; directly limits stress on downstream components like microcontrollers or transceivers |
| PPPM | 1500 W - peak pulse power handling capacity; enables protection against lightning-induced surges (IEC 61000-4-5 Level 4) on 24 V industrial buses |
| TJ max. | +175 °C - maximum junction temperature; supports operation in under-hood automotive environments and high-power industrial enclosures |
| Leakage @ VWM | 1.0 µA - ultra-low reverse leakage ensures minimal standby power loss and no signal distortion in high-impedance analog sensing paths |
Pinout & Package
Package: JEDEC 1.5KE molded epoxy case (Case Style 1.5KE), axial-leaded, RoHS-compliant, matte tin-plated leads. Dimensions: 5.3 mm diameter × 9.5 mm length (0.210" × 0.375"), UL 94 V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional terminal pair | No polarity marking; either lead serves as anode or cathode depending on transient polarity - simplifies PCB layout and eliminates orientation errors |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure (JESD22-A101) |
| 1500 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 4th-level surge immunity (4 kV line-to-earth) without external series impedance in low-Z power rails |
| AEC-Q101 qualified (HE3_B variant) | Validated for automotive applications including engine control modules, body electronics, and ADAS sensor interfaces per stress test requirements |
| Sub-nanosecond response time | Clamps transients within <1 ns - faster than MOVs or polymer-based protectors - preserving integrity of high-speed digital signals (e.g., CAN FD, LIN) |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes overvoltage overshoot during surge events, reducing risk of gate oxide rupture in protected MOSFETs or logic ICs |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | DO-214AA (SMB) package; lower PPPM = 600 W; VBR = 71.1–78.6 V; VC = 103 V @ 5.8 A | Compact surface-mount alternative for space-constrained designs; insufficient for 1500 W surge events | Select SMBJ64CA only when board real estate is critical and peak surge energy is ≤600 W (e.g., secondary-side signal line protection). |
| 1.5KE62CAHE3_A | Same electrical specs and 1.5KE package; differs only in revision code ("A" vs "B"); both AEC-Q101 qualified per note (2) | No functional difference; "A" and "B" denote minor process or test revision - fully interchangeable in all applications | Choose 1.5KE62CAHE3_A or 1.5KE62CAHE3_B/C based on distributor stock availability; no design or qualification impact. |

FAQ
What is the breakdown voltage tolerance for 1.5KE62CAHE3_B/C?
The 1.5KE62CAHE3_B/C has a specified breakdown voltage range of 58.9 V to 65.1 V at 1.0 mA test current, corresponding to ±10% tolerance around the nominal 62 V rating. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes, critical for protecting 53 V-rated systems without premature conduction.
Is 1.5KE62CAHE3_B/C suitable for automotive applications?
Yes, 1.5KE62CAHE3_B/C is AEC-Q101 qualified per note (2) in the Vishay datasheet, covering the full 1.5KE6.8CAHE3_B to 1.5KE220CAHE3_B family. It meets stress tests for temperature cycling, humidity, mechanical shock, and high-temperature reverse bias - validated for use in engine control units, body control modules, and ADAS sensor harnesses.
How does the bidirectional nature of 1.5KE62CAHE3_B/C affect its placement on a PCB?
The 1.5KE62CAHE3_B/C has no polarity marking and conducts identically in both directions, allowing placement across any two points requiring symmetrical overvoltage protection - such as AC signal lines, differential buses (CAN, RS-485), or floating power domains. No orientation check is required during assembly, reducing manufacturing error risk.
What is the maximum clamping voltage of 1.5KE62CAHE3_B/C under surge conditions?
The maximum clamping voltage (VC) of 1.5KE62CAHE3_B/C is 85.0 V at 17.6 A peak pulse current (10/1000 µs waveform). This value represents the highest voltage seen across the device during worst-case surge events and directly determines the overvoltage stress imposed on downstream components like microcontrollers or interface ICs.
Does 1.5KE62CAHE3_B/C require a heatsink for continuous operation?
No heatsink is required for 1.5KE62CAHE3_B/C under normal operating conditions because it handles only transient energy - not continuous power. Its 6.5 W steady-state power dissipation rating applies only under forced cooling (infinite heatsink at TL = 75 °C); in typical PCB mounting, thermal management relies on short-duration pulse handling, not sustained thermal transfer.
