Product details
Overview
1.5SMC130CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 130 V standoff voltage (VWM), 179 V clamping voltage (VC) at 8.4 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the 1.5SMC130CAHE3_A/H datasheet, 1.5SMC130CAHE3_A/H pinout, 1.5SMC130CAHE3_A/H application, or 1.5SMC130CAHE3_A/H equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification for automotive use, SMC (DO-214AB) package thermal performance, and compliance with UL 497B surge protector classification.
Technical Context
This device operates as a voltage-clamped crowbar during transient overvoltage events, leveraging an avalanche breakdown mechanism to shunt surge current away from downstream circuitry. Its bidirectional structure enables symmetrical clamping in both polarities without polarity marking, supporting AC-coupled or floating signal paths.
Designed for repetitive surge handling at 0.01% duty cycle, it delivers low incremental surge resistance and sub-nanosecond response time. Thermal performance is characterized by RθJA = 75 °C/W on standard 8.0 mm × 8.0 mm copper pads, with maximum junction temperature rated at +150 °C and MSL Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - Maximum continuous reverse voltage before clamping initiates; defines operating margin below breakdown in normal conditions. |
| VBR (Breakdown Voltage) | 124–137 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on under transients. |
| VC (Clamping Voltage) | 179 V at IPPM = 8.4 A - Peak voltage seen by protected circuit during 10/1000 μs surge; critical for IC survivability. |
| PPPM (Peak Pulse Power) | 1500 W - Energy-handling capacity per IEEE C62.35 10/1000 μs waveform; supports lightning and inductive-switching surges. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Negligible standby current; avoids loading sensitive analog or low-power circuits. |
| TJ max | +150 °C - Enables operation in under-hood automotive or industrial environments without derating. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test requirements; required for ECU, ADAS, and body control modules. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; common node in bidirectional configuration | No polarity marking - symmetric conduction in either direction; connects to protected line or ground reference point. |
| Cathode | Current exit terminal in forward bias; common node in bidirectional configuration | Identical electrical role to Anode due to bidirectional construction; no functional distinction in layout or routing. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), or ungrounded power rails without polarity concerns. |
| 1500 W peak pulse power | Withstands IEC 61000-4-5 Level 4 (4 kV surge) and ISO 7637-2 Pulse 1/2a/5a in automotive applications when properly laid out. |
| AEC-Q101 qualification | Validated for temperature cycling, HTRB, UHAST, and mechanical shock - required for Tier 1 automotive supply chain compliance. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ESD or relay bounce), improving protection margin. |
| MSL Level 1, 260 °C reflow | Compatible with standard lead-free SMT assembly processes without pre-baking; reduces manufacturing complexity and cost. |
Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |
|---|---|
Use Scenario: Protecting CAN/FlexRay transceiver inputs and analog sensor feeds (e.g., pressure, temperature) from load dump and jump-start transients. IC Role / Device Role: Primary surge shunt element placed between signal line and chassis ground. Use Value: Clamps 130 V nominal bus to ≤179 V during 8.4 A surge, preserving signal integrity and preventing MCU ADC input damage. |
Use Scenario: Shielding 4–20 mA current loop inputs in programmable logic controllers against field-wiring induced surges. IC Role / Device Role: Bidirectional line protector across input terminals, referenced to isolated system ground. Use Value: Symmetric clamping eliminates need for dual unidirectional devices; maintains loop accuracy with <1 μA leakage at 111 V. |
| Telecom Line Card Protection | Consumer Power Adapter EMI Filter |
Use Scenario: Safeguarding Ethernet PHY or DSL line drivers from lightning-induced surges on outdoor-facing ports. IC Role / Device Role: Secondary-level TVS after gas discharge tube (GDT) primary protection. Use Value: Fast response (<1 ns) and 1500 W rating enable coordination with upstream GDTs for full IEC 61000-4-5 compliance. |
Use Scenario: Suppressing switching noise and line transients at AC-DC adapter input stage before bridge rectifier. IC Role / Device Role: Bidirectional clamp across L-N or L/N-to-earth, absorbing differential-mode surges. Use Value: UL 497B recognition and 111 V VWM allow direct integration into safety-certified designs without additional isolation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | Same VWM/VBR/VC specs but SMB package (smaller footprint, higher RθJA = 85 °C/W); lower PPPM = 600 W. | Limited to lower-energy surges; unsuitable for IEC 61000-4-5 Level 4 or automotive load dump. | Select only for space-constrained consumer applications where 600 W surge margin suffices. |
| 1.5KE130CA | Through-hole DO-201 package; identical electrical specs but slower thermal response and no AEC-Q101 qualification. | Not approved for automotive production; requires wave-solder or hand-solder process; incompatible with automated SMT lines. | Use only for prototyping or legacy through-hole designs where RoHS-compliant SMT is not required. |
Compared with 1.5SMC130CAHE3_A/H, SMBJ130CA trades surge robustness for board area, while 1.5KE130CA sacrifices automotive qualification and SMT compatibility for legacy manufacturability - neither offers drop-in replacement capability.

FAQ
What is the clamping voltage of the 1.5SMC130CAHE3_A/H under a 10/1000 μs surge?
The 1.5SMC130CAHE3_A/H has a maximum clamping voltage (VC) of 179 V at 8.4 A peak pulse current with a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during standardized surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5SMC130CAHE3_A/H suitable for automotive applications?
Yes, the 1.5SMC130CAHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use with ordering code suffix HE3. It undergoes stress testing including temperature cycling, HTRB, and UHAST, making it appropriate for engine control units, ADAS sensors, and body electronics where reliability under harsh environmental conditions is mandatory.
What does the "CA" suffix indicate in 1.5SMC130CAHE3_A/H?
The "CA" suffix in 1.5SMC130CAHE3_A/H denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., 1.5SMC130A), it has no cathode marking and functions identically regardless of polarity applied across its terminals.
What package type is used for the 1.5SMC130CAHE3_A/H?
The 1.5SMC130CAHE3_A/H uses the SMC (DO-214AB) surface-mount package: dimensions 7.11 mm × 6.22 mm × 2.62 mm, with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. It supports reflow up to 260 °C (MSL Level 1) and meets UL 94 V-0 flammability requirements.
How does the 1.5SMC130CAHE3_A/H compare to unidirectional 1.5SMC130AHE3_A/H?
The 1.5SMC130CAHE3_A/H differs from the unidirectional 1.5SMC130AHE3_A/H solely in polarity configuration: CA is bidirectional (no polarity marking, symmetrical clamping), while A is unidirectional (cathode band marked, conducts only in reverse bias). Both share identical VWM, VBR, VC, PPPM, and AEC-Q101 qualification - selection depends strictly on circuit topology.
