Product details
Overview
SMCJ90CAHE3_A/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection on power and signal lines. It features a 90 V standoff voltage (VWM), 146 V maximum clamping voltage (VC) at 10.3 A peak pulse current (IPPM), and 1500 W peak pulse power dissipation (PPPM) with 10/1000 μs waveform - deployed in automotive power supply rails and industrial sensor interfaces.
For engineers reviewing the SMCJ90CAHE3_A/H datasheet, SMCJ90CAHE3_A/H pinout, SMCJ90CAHE3_A/H application, or SMCJ90CAHE3_A/H equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, 1500 W surge rating, low thermal resistance (RθJL = 15 °C/W), and compatibility with automated SMT assembly on 8.0 mm × 8.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped crowbar during transients: when reverse voltage exceeds its breakdown range (100–111 V at 1 mA test current), it avalanches to limit downstream voltage to ≤146 V. Its bidirectional structure enables symmetric clamping in AC-coupled or floating lines without polarity concerns.
Thermally, it sustains 150 °C junction temperature with RθJA = 75 °C/W (on standard pad layout) and RθJL = 15 °C/W, enabling reliable operation under repetitive surge stress in automotive engine control units and industrial PLC I/O modules.
Key Specifications

| VWM | 90 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 100 V / 111 V at 1 mA - guaranteed avalanche onset window for predictable turn-on |
| VC @ IPPM | 146 V at 10.3 A - clamped voltage seen by protected circuit during 10/1000 μs surge |
| PPPM | 1500 W - peak transient energy handling capacity per single 10/1000 μs pulse |
| ID @ VWM | 1.0 μA - leakage current at rated standoff voltage, ensuring minimal standby power loss |

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump (ISO 16750-2) and alternator ripple surges. IC Role / Device Role / Timing Role: Bidirectional TVS placed across input rail to clamp transients before LDOs or microcontrollers. Use Value: 1500 W PPPM and 146 V VC ensure compliance with ISO 7637-2 Pulse 5a while maintaining <100 ns response time. | Use Scenario: Shielding analog outputs (e.g., 4–20 mA loops) in factory automation sensors from ESD and inductive switching noise. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp on differential signal pairs to preserve signal integrity. Use Value: Symmetric clamping avoids DC offset shift; 1.0 μA ID at 90 V minimizes loading on precision current sources. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ90CAHE3_A/H | Lower PPPM (600 W), smaller SMB (DO-214AA) package, same VWM/VBR/VC specs | Reduced surge margin; suitable only for lower-energy threats (e.g., IEC 61000-4-2 ESD) | Select when board space is constrained and surge threat level is below 1 kV/42 Ω IEC 61000-4-5 |
| SMCJ90AHE3_A/H | Unidirectional version; cathode band marking; identical VWM/VBR/VC but asymmetric conduction | Requires correct polarity placement; not usable on AC or floating lines | Choose only for DC rails where polarity is fixed and reverse leakage must be minimized |
Compared with SMCJ90CAHE3_A/H, SMBJ90CAHE3_A/H trades surge capacity for footprint reduction, while SMCJ90AHE3_A/H sacrifices bidirectionality for marginally lower leakage - neither offers pin-compatible replacement without layout or system-level validation.

FAQ
What is the clamping voltage of SMCJ90CAHE3_A/H at its rated peak pulse current?
The SMCJ90CAHE3_A/H has a maximum clamping voltage (VC) of 146 V when subjected to its specified peak pulse current (IPPM) of 10.3 A using the 10/1000 μs waveform. This value is measured under standardized test conditions per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during surge events. The SMCJ90CAHE3_A/H maintains this clamping performance across its full operating temperature range.
Is SMCJ90CAHE3_A/H suitable for automotive applications?
Yes, SMCJ90CAHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use with ordering code suffix HE3. It meets requirements for temperature cycling, high-temperature reverse bias, and mechanical shock relevant to engine control units, body electronics, and ADAS power domains. The SMCJ90CAHE3_A/H also complies with UL 94 V-0 and J-STD-020 MSL Level 1, supporting reflow assembly in automotive manufacturing lines.
How does the bidirectional design of SMCJ90CAHE3_A/H affect its circuit implementation?
The bidirectional architecture of SMCJ90CAHE3_A/H eliminates polarity sensitivity, allowing placement across AC-coupled lines, transformer secondaries, or floating differential pairs without orientation constraints. Unlike unidirectional variants, the SMCJ90CAHE3_A/H has no cathode band marking and provides identical clamping behavior for both positive and negative transients - simplifying layout and reducing BOM count in systems with mixed-signal or dual-polarity interfaces.
What is the thermal resistance profile of SMCJ90CAHE3_A/H and how does it impact PCB layout?
SMCJ90CAHE3_A/H exhibits RθJL = 15 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient) when mounted on the recommended 8.0 mm × 8.0 mm copper pads per terminal. To maintain safe junction temperatures under repeated surges, PCB layout must replicate this pad area and avoid thermal isolation. The SMCJ90CAHE3_A/H thermal performance directly determines maximum allowable surge repetition rate and ambient operating temperature ceiling.
Does SMCJ90CAHE3_A/H meet RoHS and halogen-free requirements?
Yes, SMCJ90CAHE3_A/H carries the HE3 suffix, indicating RoHS-compliant construction per EU Directive 2011/65/EU and material categorization per Vishay document 99912. It contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE. While not halogen-free (which requires HM3 suffix), the SMCJ90CAHE3_A/H uses brominated flame retardants within regulatory limits and passes UL 94 V-0 flammability testing.
