Product details
Overview
1.5KE62AHE3_B/C from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-side overvoltage protection in DC power rails 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, 53.0 V stand-off voltage (VWM), and operates across –55 °C to +175 °C junction temperature range - deployed in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1.5KE62AHE3_B/C datasheet, 1.5KE62AHE3_B/C pinout, 1.5KE62AHE3_B/C application, or 1.5KE62AHE3_B/C equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, AEC-Q101 qualification status, thermal resistance (RθJL = 15.4 °C/W), and direct alternative part comparisons - all grounded in Vishay Document #88301 (Rev. 09-Aug-2022).
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time (<1 ns) and low incremental surge resistance. Its clamping behavior is defined by a 10/1000 µs waveform with 0.01% duty cycle, and it sustains 200 A non-repetitive forward surge current (8.3 ms half-sine) while maintaining VF ≤ 5.0 V at 100 A.
The device complies with UL 497B (QVGQ2 recognition), meets JESD 201 Class 2 whisker resistance (HE3 suffix), and is RoHS-compliant. Thermal performance is characterized by RθJA = 75 °C/W and RθJL = 15.4 °C/W, enabling reliable operation without heatsinking up to 6.5 W continuous power dissipation at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at IT = 1 mA - defines precise voltage threshold where avalanche conduction begins under transient stress |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA, ensuring no false triggering in normal operation |
| VC @ IPPM | 85.0 V at 17.6 A - clamped voltage during 1500 W transient, limiting downstream IC stress to safe levels |
| PPPM | 1500 W (10/1000 µs) - peak surge energy handling capacity suitable for lightning-induced transients per REA PE.60 |
| IFSM | 200 A (8.3 ms half-sine) - surge current rating confirming robustness against inductive switch-off spikes |
| TJ Range | –55 °C to +175 °C - enables deployment in under-hood automotive and high-temp industrial environments |
| RθJL | 15.4 °C/W - low junction-to-lead thermal resistance supports high-power pulse dissipation without PCB copper pour |

Use Value: Suppresses 85 V clamped transients within MOSFET SOA limits, eliminating need for snubbers and reducing BOM count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | Lower PPPM (600 W), smaller SMB package (RθJL = 25 °C/W), same VBR range (60.8–67.2 V) | Not AEC-Q101 qualified; limited to consumer/industrial use; lower surge margin for ISO 7637-2 | Select when board space is constrained and surge requirements are ≤600 W; verify thermal derating at elevated ambient. |
| 1.5KE62CA | Bidirectional variant (VBR = 58.9–65.1 V, same clamping), identical package and power rating | Required for AC-coupled or floating signal lines (e.g., RS-485, Ethernet PHY) where polarity reversal occurs | Choose only if bidirectional clamping is needed; note that 1.5KE62AHE3_B/C is unidirectional and cannot replace CA variants in symmetric circuits. |
Compared with SMBJ64A, 1.5KE62AHE3_B/C delivers 2.5× higher surge power and superior thermal coupling to leads, making it preferred for automotive and high-reliability industrial use; versus 1.5KE62CA, it lacks bidirectional capability but offers lower cost and simpler layout for DC-rail-only protection.

FAQ
What is the breakdown voltage tolerance for 1.5KE62AHE3_B/C?
The 1.5KE62AHE3_B/C has a specified breakdown voltage range of 58.9 V to 65.1 V at test current IT = 1 mA, per Vishay Document #88301. This ±5% tolerance ensures consistent clamping onset across production lots and supports robust design margins for 60 V nominal systems. The parameter is measured under controlled 25 °C conditions and remains stable over the full –55 °C to +175 °C operating junction temperature range.
Is 1.5KE62AHE3_B/C AEC-Q101 qualified?
Yes, 1.5KE62AHE3_B/C is AEC-Q101 qualified, as confirmed in Vishay Document #88301 (Note 2 on page 3). Qualification covers the full 1.5KE6.8AHE3_B to 1.5KE220AHE3_B family and validates performance under stress tests including HTGB, HTRB, TCT, and mechanical shock - making it suitable for automotive powertrain and chassis applications.
What is the maximum clamping voltage of 1.5KE62AHE3_B/C at rated peak pulse current?
The maximum clamping voltage (VC) of 1.5KE62AHE3_B/C is 85.0 V at IPPM = 17.6 A, corresponding to its 1500 W peak pulse power rating with a 10/1000 µs waveform. This value is guaranteed per datasheet Table on page 2 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Can 1.5KE62AHE3_B/C be used in bidirectional signal protection?
No, 1.5KE62AHE3_B/C is a unidirectional TVS diode and must not be used for bidirectional signal protection. Its cathode-band marking and asymmetric IV curve mean it only clamps in reverse bias. For AC or floating lines like RS-485 or USB D+/D–, the bidirectional variant 1.5KE62CA must be selected instead - using 1.5KE62AHE3_B/C in such roles risks catastrophic failure during positive half-cycle transients.
What is the thermal resistance from junction to lead (RθJL) for 1.5KE62AHE3_B/C?
The junction-to-lead thermal resistance (RθJL) of 1.5KE62AHE3_B/C is 15.4 °C/W, per Vishay Document #88301 (page 3, Thermal Characteristics table). This low value reflects efficient heat transfer from the silicon die through the leads, enabling high peak power dissipation without external heatsinking - critical for compact automotive and industrial designs where PCB copper area is limited.
