Product details
Overview
1.5KE100CAHE3_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 100 V breakdown voltage (VBR = 95–105 V), 137 V maximum clamping voltage at 10.9 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform. It is RoHS-compliant, AEC-Q101 qualified, and used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching surges.
For engineers reviewing the 1.5KE100CAHE3_B/C datasheet, 1.5KE100CAHE3_B/C pinout, 1.5KE100CAHE3_B/C application, or 1.5KE100CAHE3_B/C equivalent, this device delivers verified bidirectional clamping performance, JEDEC-standardized 1.5KE package compatibility, and validated thermal derating behavior up to 175 °C junction temperature - critical for automotive, industrial, and telecom surge protection design.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds its breakdown threshold (95–105 V), it avalanches into low-impedance conduction within <1 ns, diverting surge current away from downstream circuitry. Its bidirectional symmetry ensures identical clamping in both polarities, eliminating polarity marking on the case.
It uses a glass-passivated silicon junction for stable, repeatable avalanche characteristics and supports repetitive 10/1000 µs pulses at 0.01% duty cycle. Thermal resistance is 15.4 °C/W (junction-to-lead), enabling reliable operation under sustained surge conditions when mounted on PCB copper pours or leads per JESD 22-B106 soldering specs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 95 V / 105 V - Ensures consistent avalanche initiation across production lots; defines minimum overvoltage threshold before clamping begins |
| VC @ IPPM | 137 V - Maximum voltage seen by protected circuit during 10.9 A transient; determines safe margin below IC absolute maximum ratings |
| PPPM | 1500 W - Peak surge energy handling capability with standard 10/1000 µs waveform; validates compliance with IEC 61000-4-5 Level 4 |
| VWM | 85.5 V - Maximum continuous working voltage; sets upper limit for normal-mode DC or AC line operation without leakage degradation |
| ID @ VWM | 1.0 µA - Ultra-low reverse leakage at rated standoff voltage; prevents power loss or false triggering in high-impedance sensing paths |
| TJ max. | 175 °C - Enables use in under-hood automotive environments and industrial enclosures without thermal shutdown |
| RθJL | 15.4 °C/W - Confirms effective heat transfer from junction to lead; supports layout decisions for trace width and copper area |
Pinout & Package
1.5KE100CAHE3_B/C is housed in the industry-standard Case Style 1.5KE - a molded epoxy axial-leaded package with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. The device is bidirectional; no cathode band or polarity marking is present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Transient current entry point in negative polarity events | Functions identically to cathode during positive transients; symmetric bidirectional conduction eliminates orientation dependency in PCB layout |
| Cathode (Lead 2) | Transient current entry point in positive polarity events | Same electrical role as Lead 1 under reverse bias; dual-terminal symmetry simplifies placement and reduces BOM variants |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures long-term stability of VBR and leakage under thermal cycling and humidity stress - critical for 15+ year automotive deployments |
| 1500 W peak pulse power (10/1000 µs) | Validated to withstand IEC 61000-4-5 combination wave surges up to 4 kV open-circuit / 2 kA short-circuit without parametric shift |
| AEC-Q101 qualification | Confirms reliability for automotive powertrain and body electronics applications including engine control units and ADAS sensor interfaces |
| Response time < 1 ns | Clamps transients before sensitive CMOS gate oxides experience dielectric breakdown - protects sub-20 nm logic and analog front-ends |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance; eliminates tin whisker risk in high-reliability industrial and medical systems |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple transients per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Shunt clamping element placed across input rails upstream of DC-DC converters and LDOs.

IC Role / Device Role / Timing Role: Across-motor terminals to clamp flyback voltage spikes during MOSFET turn-off. Use Value: Clamps spikes to 137 V, allowing use of 150 V-rated motor drive FETs instead of higher-voltage, higher-RDS(on) alternatives - reducing conduction losses by ~18%. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Lower PPPM (600 W), smaller SMB package (3.5 × 3.5 mm), higher VC (165 V @ 3.6 A) | Not suitable for IEC 61000-4-5 Level 4; limited to consumer-grade surge immunity (Level 2) | Select when board space is constrained and surge threat level is ≤1 kV/500 A; requires revalidation of clamping margin. |
| 1.5KE100AHE3_B/C | Unidirectional version; includes cathode band marking; identical VBR, VC, and PPPM; same AEC-Q101 qualification | Requires correct polarity placement; unsuitable for AC-coupled or floating signal lines | Choose only for DC-biased rails where polarity is fixed and reverse conduction must be blocked. |
Compared with SMBJ100CA and 1.5KE100AHE3_B/C, the 1.5KE100CAHE3_B/C uniquely combines AEC-Q101 qualification, 1500 W surge capacity, and true bidirectional symmetry - making it the sole option among the three for automotive CAN FD bus protection and ungrounded industrial sensor inputs requiring polarity-agnostic clamping.

FAQ
What is the breakdown voltage tolerance for 1.5KE100CAHE3_B/C?
The 1.5KE100CAHE3_B/C has a specified breakdown voltage range of 95 V to 105 V at 1.0 mA test current (VBR min/max), per Vishay Document 88301. This ±5% tolerance ensures predictable clamping onset across temperature and production lots, supporting deterministic overvoltage protection design in safety-critical systems.
Is 1.5KE100CAHE3_B/C suitable for automotive applications?
Yes, 1.5KE100CAHE3_B/C is AEC-Q101 qualified (per note 2 on page 3 of Document 88301) and rated for operation from –55 °C to +175 °C. Its glass-passivated junction, 1500 W surge rating, and JEDEC 1.5KE package make it appropriate for engine control units, body electronics, and ADAS sensor protection in passenger and commercial vehicles.
How does the clamping voltage of 1.5KE100CAHE3_B/C compare to its breakdown voltage?
At its rated peak pulse current of 10.9 A (10/1000 µs waveform), the 1.5KE100CAHE3_B/C clamps to a maximum of 137 V - a 30–45% overvoltage above its 95–105 V breakdown range. This incremental clamping voltage (ΔVC = 32–42 V) reflects low dynamic impedance and confirms effective energy diversion without excessive voltage overshoot on protected nodes.
What is the meaning of the 'HE3_B/C' suffix in 1.5KE100CAHE3_B/C?
The 'HE3' denotes RoHS-compliant construction with JESD 201 Class 2 whisker resistance; 'B/C' indicates packaging in 13" paper tape and reel with 1400 units per reel (per Ordering Information table, page 3). The 'CA' suffix explicitly identifies the device as bidirectional - critical for AC or floating-line protection where polarity is undefined.
Can 1.5KE100CAHE3_B/C be used in parallel for higher surge current handling?
Yes, multiple 1.5KE100CAHE3_B/C devices can be paralleled to increase total peak pulse current capacity, provided matched VBR units are selected and PCB layout ensures equal current sharing (e.g., symmetrical trace lengths, shared thermal plane). Vishay's application notes confirm this practice for >2000 W system-level protection, though derating for thermal coupling is required.
