Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting 12V/24V battery-fed ECUs from load dump (ISO 7637-2 Pulse 5a) and alternator-induced spikes. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp transients within safe limits before they reach MCU or CAN transceivers. Use Value: Limits clamped voltage to 137V at 11.4A, preventing damage to 36V-rated power management ICs and ensuring functional safety compliance. | Use Scenario: Safeguarding digital input channels of programmable logic controllers exposed to inductive kickback from solenoids and relays. IC Role / Device Role / Timing Role: Standoff protection element across input terminals, absorbing 10/1000μs surges induced by contactor switching. Use Value: Withstands >1000 cycles of 1500W pulses without degradation, extending field service life and reducing maintenance downtime. |
| LED Driver Overvoltage Suppression | DC Power Supply ESD Hardening |
Use Scenario: Preventing catastrophic failure of constant-current LED drivers subjected to lightning-induced surges on long DC feeder lines. IC Role / Device Role / Timing Role: Primary clamping device on input bus, activated within <1ps to limit voltage excursion before driver IC's internal FETs rupture. Use Value: Clamps 1kV open-circuit transients to ≤137V, preserving driver IC integrity and maintaining luminous output stability. | Use Scenario: Adding secondary-level ESD protection to 48V telecom or server PSUs where primary MOVs may not respond fast enough to human-body-model (HBM) events. IC Role / Device Role / Timing Role: Fast-response TVS placed downstream of bulk filtering to catch residual fast-rising transients missed by slower protectors. Use Value: Sub-1ps response ensures clamping occurs before 100ns HBM pulses propagate into DC-DC controller ICs, eliminating latch-up risk. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | DO-214AA (SMB) package, 100W lower peak power (1000W), slightly higher VC (156V @ 6.4A) | Lower surge margin; suitable for space-constrained PCBs where DO-201 mounting is impractical | Select SMBJ100A only if board layout prohibits axial DO-201 placement and 1000W rating suffices for target threat level. |
| 1.5KE100CA | Bidirectional variant (same VBR, VC, package); symmetrical clamping in both polarities | Required for AC-coupled or floating signal lines where polarity reversal is possible | Choose 1.5KE100CA only when protecting bidirectional data lines or transformer-coupled interfaces-not for DC power rail use. |
Compared with SMBJ100A and 1.5KE100CA, the 1.5KE100A R0G provides higher surge energy handling (1500W vs. 1000W) and lower clamping voltage (137V vs. 156V), making it preferable for demanding automotive power rail applications where margin and thermal robustness are critical.

FAQ
What is the clamping voltage of the 1.5KE100A R0G under full-rated surge current?
The 1.5KE100A R0G has a maximum clamping voltage (VC) of 137V at 11.4A peak impulse current (IPP), measured using the standard 10/1000μs double-exponential waveform. This value is guaranteed across temperature and lifetime, and directly determines the maximum overvoltage stress imposed on downstream circuitry during a 1500W transient event. The 1.5KE100A R0G maintains this clamping performance while operating within its −55°C to +175°C junction temperature range.
Is the 1.5KE100A R0G AEC-Q101 qualified?
Yes, the 1.5KE100A R0G is AEC-Q101 qualified. This certification confirms that the device has passed rigorous stress tests-including high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock-required for automotive electronic components. The "A" suffix in 1.5KE100A denotes the AEC-Q101-compliant version, and the "R0G" ordering code indicates green (halogen-free) packaging. The 1.5KE100A R0G is intended for under-hood and chassis-mounted applications where reliability under thermal and vibration stress is mandatory.
How does the 1.5KE100A R0G differ from the 1.5KE100CA variant?
The 1.5KE100A R0G is unidirectional, while the 1.5KE100CA is bidirectional-meaning the latter clamps transients of either polarity symmetrically. Both share identical breakdown (95–105V), clamping (137V), and power ratings (1500W), but the 1.5KE100CA lacks anode/cathode polarity marking and must be used where voltage reversals occur. The 1.5KE100A R0G is appropriate for DC power rail protection; using it in AC or floating applications risks failure. Always verify polarity assignment before substituting the 1.5KE100A R0G for the 1.5KE100CA.
What is the maximum steady-state power dissipation for the 1.5KE100A R0G?
The 1.5KE100A R0G has a steady-state power dissipation (PD) rating of 5W at a lead temperature (TL) of 75°C, measured with 0.375" (9.5mm) lead lengths mounted on a 0.6" × 0.6" copper pad. This rating applies only to continuous DC or low-frequency reverse-bias leakage-not to transient events. In normal operation, leakage current remains below 1μA above 85.5V, resulting in negligible steady-state heating. The 1.5KE100A R0G is not intended for continuous power regulation; its design purpose is single-event surge absorption.
Does the 1.5KE100A R0G meet ISO 7637-2 immunity requirements?
Yes, the 1.5KE100A R0G is explicitly rated to meet ISO 7637-2 for Pulses 1, 2a, 2b, 3a, and 3b-covering key automotive transient threats including supply disconnection, load dump simulation, and capacitive coupling noise. Its 1500W peak power rating, fast <1.0ps response, and low clamping ratio ensure compliance when correctly applied with appropriate PCB layout (short traces, low-inductance grounding). The 1.5KE100A R0G is widely deployed in TCU, BCM, and ADAS modules certified to ISO 16750-2 and OEM-specific EMC specifications.
