Product details
Overview
1.5KE16AHE3_B/C from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 1500 W peak pulse power rating (10/1000 µs), 15.2–16.8 V breakdown voltage at 1.0 mA test current, 13.6 V maximum stand-off voltage, 22.5 V clamping voltage at 66.7 A peak pulse current, and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1.5KE16AHE3_B/C datasheet, 1.5KE16AHE3_B/C pinout, 1.5KE16AHE3_B/C application, or 1.5KE16AHE3_B/C equivalent, this part delivers verified surge immunity for industrial power supplies, automotive body electronics, and telecom interface circuits - with RoHS-compliant matte tin leads, AEC-Q101 qualification, and JESD 201 Class 2 whisker resistance.
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 tightly controlled 15.2–16.8 V breakdown range and 22.5 V maximum clamping voltage at 66.7 A, enabling predictable voltage limiting during transient events.
The device supports repetitive surge duty cycles up to 0.01 % and is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine). Thermal performance is characterized by 15.4 °C/W junction-to-lead thermal resistance, supporting reliable operation under high-energy transients without external heatsinking in standard PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 15.2–16.8 V at 1.0 mA - defines precise turn-on threshold for overvoltage clamping |
| Stand-off Voltage (VWM) | 13.6 V max - ensures no conduction during normal 12 V rail operation |

IC Role / Device Role / Timing Role: Final-stage protector after DC-DC regulation, before USB or peripheral connectors. Use Value: 13.6 V VWM avoids false triggering during 12 V ±10 % line regulation, while 22.5 V VC protects downstream USB-PD controllers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | DO-214AA package (SMB), 600 W PPPM, same VBR range (15.2–16.8 V), lower clamping (20.1 V @ 30 A) | Lower surge rating suits consumer-grade designs; surface-mount footprint reduces board space vs. axial leads | Select SMBJ16A when PCB real estate is constrained and 600 W surge immunity suffices |
| 1.5KE16CA | Bidirectional variant (no polarity marking), identical VBR/VC/PPPM, but rated only to 220 V VBR max (not applicable here) | Required for AC-coupled or floating signal lines where polarity reversal occurs (e.g., RS-232, analog sensors) | Choose 1.5KE16CA only if bidirectional clamping is needed; 1.5KE16AHE3_B/C is optimal for DC rail protection |
Compared with SMBJ16A, the 1.5KE16AHE3_B/C delivers 2.5× higher surge energy handling in an axial package suited for through-hole ruggedness; versus 1.5KE16CA, it offers superior DC rail stability due to unidirectional blocking, eliminating leakage concerns in grounded systems.

FAQ
What is the clamping voltage of the 1.5KE16AHE3_B/C at its rated peak pulse current?
The 1.5KE16AHE3_B/C has a maximum clamping voltage (VC) of 22.5 V at 66.7 A peak pulse current (10/1000 µs waveform). This value is measured under standardized surge conditions and guarantees that downstream components experience no more than 22.5 V during a full 1500 W transient event. The clamping performance is validated across the full operating temperature range.
Is the 1.5KE16AHE3_B/C suitable for automotive applications?
Yes, the 1.5KE16AHE3_B/C is AEC-Q101 qualified and explicitly listed in Vishay's qualified product list for automotive use. Its –55 °C to +175 °C operating junction temperature range, JESD 201 Class 2 whisker resistance, and robust surge handling make it appropriate for engine control units, body electronics, and infotainment power rails where reliability under thermal and electrical stress is critical.
How does the 1.5KE16AHE3_B/C differ from the standard 1.5KE16A?
The 1.5KE16AHE3_B/C includes the HE3 suffix indicating RoHS compliance and AEC-Q101 qualification, whereas the base 1.5KE16A lacks formal automotive qualification. The "B/C" denotes packaging configuration (13" paper tape and reel, 1400 pcs/reel) and revision level. Electrically and thermally, both share identical VBR, VC, PPPM, and RθJL specifications.
What is the maximum leakage current of the 1.5KE16AHE3_B/C at its stand-off voltage?
The 1.5KE16AHE3_B/C exhibits a maximum reverse leakage current (ID) of 1.0 µA at its rated stand-off voltage of 13.6 V, measured at 25 °C ambient. This ultra-low leakage ensures minimal power drain in always-on systems such as automotive wake-up circuits or battery-backed industrial sensors.
Can the 1.5KE16AHE3_B/C be used in bidirectional signal protection?
No - the 1.5KE16AHE3_B/C is a unidirectional TVS diode, intended for DC rail protection where polarity is fixed. For bidirectional signal lines (e.g., RS-485, CAN, analog sensors), the 1.5KE16CA variant must be used instead. Using the unidirectional 1.5KE16AHE3_B/C on AC or floating signals risks forward conduction and improper clamping behavior.
