Product details
Overview
1.5KE13AHE3_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 12.4 V minimum breakdown voltage (VBR), 11.1 V maximum standoff voltage (VWM), 18.2 V clamping voltage (VC) at 82.4 A peak pulse current, 1500 W peak pulse power rating with 10/1000 µs waveform, 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 1.5KE13AHE3_B/C datasheet, 1.5KE13AHE3_B/C pinout, 1.5KE13AHE3_B/C application, or 1.5KE13AHE3_B/C equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance data (RθJA = 75 °C/W), JEDEC 1.5KE package dimensions, and real-world clamping behavior under lightning-surge and inductive-switching transients.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its clamping action begins at 12.4 V (min VBR) and limits voltage to ≤18.2 V at 82.4 A (10/1000 µs), enabling robust protection of downstream MOSFETs and ICs against ESD, load dump, and inductive kickback.
The device complies with AEC-Q101 stress testing for automotive applications and supports soldering per J-STD-002/JESD 22-B102. Matte tin-plated leads meet JESD 201 Class 2 whisker resistance, and the molded epoxy case achieves UL 94 V-0 flammability rating - confirming suitability for under-hood and high-reliability embedded environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min) | 12.4 V - ensures reliable conduction onset before damage threshold of protected 12 V logic or power circuits |
| VWM | 11.1 V - allows safe operation below system nominal voltage with margin against false triggering |
| VC @ IPPM | 18.2 V - limits transient voltage seen by downstream components during 82.4 A surge event |
| PPPM | 1500 W - sustains high-energy transients such as ISO 7637-2 Pulse 5a (load dump) without failure |
| IPPM | 82.4 A - quantifies maximum surge current handled with defined clamping performance |
| TJ max | +175 °C - enables placement near heat-generating components in engine control units |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | DO-214AA package (smaller footprint), 13.3 V VBR min, 200 W PPPM, lower IPPM (10.3 A) | Not AEC-Q101 qualified; suited for space-constrained consumer PCBs, not under-hood automotive | Select when board area is constrained and surge energy is ≤200 W; verify thermal relief for continuous 6.5 W dissipation. |
| 1.5KE13CA | Bidirectional variant (same VBR/VC), no polarity marking, symmetric clamping in both directions | Required for AC-coupled or floating signal lines where reverse polarity transients occur (e.g., RS-485 bus) | Choose only if bidirectional protection is needed; unidirectional 1.5KE13AHE3_B/C is optimal for DC rails with defined ground reference. |
Compared with SMBJ13A, the 1.5KE13AHE3_B/C delivers 7.5× higher surge power handling and AEC-Q101 qualification for harsh environments; versus 1.5KE13CA, it offers superior DC rail protection efficiency due to absence of reverse leakage path and tighter VWM margin.

FAQ
What is the breakdown voltage tolerance for 1.5KE13AHE3_B/C?
The 1.5KE13AHE3_B/C has a specified breakdown voltage range of 12.4 V (min) to 13.7 V (max) at 1.0 mA test current, corresponding to a ±5.3% tolerance about the nominal 13 V rating. This tight VBR window ensures predictable turn-on behavior in overvoltage protection circuits and aligns with JEDEC standard tolerances for the 1.5KE family. The 1.5KE13AHE3_B/C maintains this specification across its full operating temperature range.
Is 1.5KE13AHE3_B/C qualified for automotive use?
Yes, the 1.5KE13AHE3_B/C carries AEC-Q101 qualification per Vishay documentation (Document Number 88301, Revision 09-Aug-2022), covering stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT). Its HE3 suffix denotes RoHS compliance and AEC-Q101 qualification, making the 1.5KE13AHE3_B/C suitable for under-hood and chassis-mounted automotive modules requiring long-term reliability.
What is the maximum clamping voltage of 1.5KE13AHE3_B/C under surge conditions?
The maximum clamping voltage (VC) of the 1.5KE13AHE3_B/C is 18.2 V at 82.4 A peak pulse current with a 10/1000 µs waveform. This value is measured per standard test conditions and represents the upper limit of voltage imposed on protected circuitry during worst-case surge events. The 1.5KE13AHE3_B/C maintains this clamping performance across ambient temperatures up to 25 °C, with derating applied above that per Figure 2 in the datasheet.
How does the thermal resistance of 1.5KE13AHE3_B/C affect PCB layout?
The 1.5KE13AHE3_B/C has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W, meaning each watt of power dissipated raises the junction temperature by 75 °C above ambient. For reliable operation at full 6.5 W steady-state dissipation, PCB layout must include adequate copper pour, thermal vias, and airflow - especially critical in sealed automotive enclosures. The 1.5KE13AHE3_B/C's RθJL of 15.4 °C/W also indicates efficient heat transfer to leads, supporting through-hole mounting with short lead lengths.
Can 1.5KE13AHE3_B/C be used in bidirectional signal protection?
No, the 1.5KE13AHE3_B/C is a unidirectional TVS diode and must not be used for bidirectional signal line protection such as RS-485 or USB D+/D– lines. Its cathode-band marking and asymmetric IV curve mean it conducts only when the anode is negative relative to cathode. For bidirectional applications, the 1.5KE13CA variant - explicitly designated with 'CA' suffix - is required. Using the 1.5KE13AHE3_B/C in AC or floating systems risks incomplete protection and potential device failure during reverse-polarity transients.
