Product details
Overview
SMCJ13CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMC (DO-214AB) package, designed for clamping voltage transients on signal or power lines. It features 13 V standoff voltage (VWM), 21.5 V maximum clamping voltage at 69.8 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the SMCJ13CAHE3_A/H datasheet, SMCJ13CAHE3_A/H pinout, SMCJ13CAHE3_A/H application, or SMCJ13CAHE3_A/H equivalent, this device is selected for automotive-grade transient protection where AEC-Q101 qualification, low incremental surge resistance, and bidirectional symmetry are required in sensor interfaces, CAN bus lines, and DC power rails.
Technical Context
The SMCJ13CAHE3_A/H operates as a silicon avalanche diode with symmetrical breakdown in both directions, enabling protection of AC-coupled or floating nodes without polarity concerns. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and repeatable clamping performance across temperature (-55 °C to +150 °C).
It delivers fast response time (<1.0 ps typical) and low dynamic impedance, achieving 21.5 V clamping at 69.8 A IPPM under standardized 10/1000 μs surge conditions. Thermal resistance is 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-lead), supporting reliable operation on standard PCB copper pads (8.0 mm × 8.0 mm per terminal).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 12 V nominal systems. |
| VBR min/max | 14.4 V / 15.9 V at 1.0 mA - Confirmed breakdown threshold range ensuring predictable turn-on during overvoltage events. |
| VC @ IPPM | 21.5 V at 69.8 A - Clamped voltage seen by protected circuit during full-rated 1500 W transient; limits stress on downstream ICs. |
| PPPM | 1500 W - Peak pulse power handling capability with 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 surge immunity. |
| ID @ VWM | ≤1.0 μA - Reverse leakage current at standoff voltage; ensures minimal power loss and signal integrity in high-impedance circuits. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments and industrial enclosures. |
| AEC-Q101 | Qualified - Validated for automotive applications including engine control units, body electronics, and ADAS sensor modules. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 7.11 mm × 6.22 mm × 2.62 mm (L × W × H); matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (bidirectional) | Acts as cathode during positive surges and anode during negative surges; symmetric conduction path. |
| Cathode | Transient current exit (bidirectional) | Functions identically to Anode under reverse polarity; no band marking distinguishes terminals. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., CAN, RS-485), and floating power domains without polarity constraints. |
| AEC-Q101 qualification | Validated for automotive reliability requirements including temperature cycling, humidity bias, and mechanical shock-critical for Tier-1 ECU designs. |
| Low clamping ratio (VC/VBR ≈ 1.47) | Minimizes voltage overshoot during transients, reducing risk of latch-up or damage to 3.3 V/5 V logic and analog front-ends. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without moisture sensitivity concerns or baking requirements. |
| Glass passivated junction | Ensures long-term stability of breakdown voltage and leakage current across life cycle, especially under thermal cycling stress. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC13CA | Same VWM (13 V) and VC (21.5 V), but lower PPPM (600 W); smaller SMA package (DO-214AC). | Limited to lower-energy transients (IEC 61000-4-2 only); unsuitable for IEC 61000-4-5 Level 3+ or automotive load dump. | Select when board space is constrained and surge threat level is limited to ESD-only environments. |
| TPSMD13CA | Identical electrical specs (13 V VWM, 21.5 V VC, 1500 W), but not AEC-Q101 qualified; RoHS-compliant only. | Acceptable for industrial/commercial use but excluded from automotive production BOMs requiring AEC validation. | Choose for cost-sensitive non-automotive designs where qualification documentation is not mandated. |
Compared with SAC13CA and TPSMD13CA, the SMCJ13CAHE3_A/H uniquely combines AEC-Q101 qualification, 1500 W surge capacity, and SMC package thermal robustness-making it the only option qualified for under-hood automotive power-line protection with full ISO 7637-2 compliance.

FAQ
What is the clamping voltage of the SMCJ13CAHE3_A/H under full-rated surge conditions?
The SMCJ13CAHE3_A/H clamps to a maximum of 21.5 V when subjected to its rated peak pulse current of 69.8 A using the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's Document Number 88394, ensuring predictable overvoltage limiting for protected circuits downstream of the SMCJ13CAHE3_A/H.
Is the SMCJ13CAHE3_A/H suitable for automotive applications?
Yes, the SMCJ13CAHE3_A/H carries AEC-Q101 qualification (noted in the ordering code "HE3" suffix), making it approved for use in automotive electronic control units, ADAS sensors, and body electronics. Its -55 °C to +150 °C operating range, validated thermal performance, and compliance with ISO 7637-2 pulse tests confirm suitability for under-hood and chassis-mounted deployments involving the SMCJ13CAHE3_A/H.
Does the SMCJ13CAHE3_A/H have polarity markings on the package?
No, the SMCJ13CAHE3_A/H is a bidirectional TVS diode and carries no cathode band or polarity marking on the SMC (DO-214AB) case. Both terminals are functionally identical-each serves as anode or cathode depending on surge polarity-so orientation during placement has no electrical impact on performance of the SMCJ13CAHE3_A/H.
What is the maximum leakage current of the SMCJ13CAHE3_A/H at its standoff voltage?
The SMCJ13CAHE3_A/H exhibits a maximum reverse leakage current (ID) of 1.0 μA when biased at its 13 V standoff voltage (VWM), measured at TA = 25 °C. This low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes standby power loss in battery-operated systems using the SMCJ13CAHE3_A/H.
Can the SMCJ13CAHE3_A/H be used in place of a unidirectional TVS like SMCJ13AHE3_A/H?
No-the SMCJ13CAHE3_A/H is strictly bidirectional and lacks polarity definition, whereas the unidirectional SMCJ13AHE3_A/H requires correct anode/cathode orientation and conducts only in reverse bias. Substituting the SMCJ13CAHE3_A/H for SMCJ13AHE3_A/H may compromise protection in DC-biased circuits; always verify circuit topology and surge directionality before selecting the SMCJ13CAHE3_A/H.
