Product details
Overview
SMCJ13AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients up to 1500 W peak pulse power with 21.5 V maximum clamping voltage at 69.8 A peak pulse current and 13 V standoff voltage. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMCJ13AHE3_A/I datasheet, SMCJ13AHE3_A/I pinout, SMCJ13AHE3_A/I application, or SMCJ13AHE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 1500 W 10/1000 µs surge rating, 1.0 µA max reverse leakage at 13 V, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuitry, activating when reverse voltage exceeds 14.4 V (min breakdown) to divert transient energy away from downstream components. Its glass-passivated junction ensures stable avalanche behavior and low incremental surge resistance.
Designed for high-reliability environments, SMCJ13AHE3_A/I meets MSL Level 1 per J-STD-020, supports peak solder reflow up to 260 °C, and features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. Polarity is marked by cathode band on the SMC package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 14.4 V / 15.9 V - Breakdown voltage range at 1.0 mA test current; defines turn-on threshold |
| VC @ IPPM | 21.5 V - Clamped voltage during 10/1000 µs 69.8 A surge; determines protected circuit stress level |
| PPPM | 1500 W - Peak pulse power handling capability under standardized transient waveform |
| IPPM | 69.8 A - Maximum non-repetitive surge current the device can safely clamp |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments |
| Leakage @ VWM | 1.0 µA - Low reverse leakage preserves signal integrity and minimizes standby power loss |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile case with cathode band marking. Dimensions: 7.75 mm × 6.22 mm × 2.62 mm (L × W × H). RoHS-compliant, halogen-free option available.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to system ground or low-side reference | Provides return path during clamping; must be routed with low-inductance trace to handle 69.8 A surge |
| Cathode | Current exit terminal in forward bias; marked by band; connected to protected line | Acts as high-impedance node until VBR exceeded; placement adjacent to IC pin minimizes clamping loop inductance |
Key Features

| Glass passivated junction | Ensures consistent avalanche characteristics over lifetime and prevents moisture-induced degradation of breakdown voltage |
| MSL Level 1 rating | Enables direct placement without baking; compatible with standard 260 °C lead-free reflow profiles |
| Low incremental surge resistance | Minimizes VC overshoot during fast transients, improving protection margin for 3.3 V/5 V logic interfaces |
| 1500 W 10/1000 µs rating | Handles ISO 7637-2 Pulse 1, 2a, 3a/b, and IEC 61000-4-5 Level 4 surges without degradation |
Applications
| Automotive Power Distribution | Industrial Sensor Signal Lines |
|---|---|
Use Scenario: Protection of 12 V battery-fed ECUs against load dump and inductive switching spikes in engine control modules. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and ground to clamp transients above 14.4 V within nanoseconds.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/57T | Lower PPPM (400 W), smaller SMA package, same VWM/VC specs | Not suitable for ISO 7637-2 Pulse 5a load dump; limited to lower-energy transients | Select when board space is constrained and surge threat level is ≤ 400 W |
| SMCJ13CAHE3_A/I | Bidirectional variant; identical VWM, VBR, and VC, but symmetric clamping in both polarities | Required for AC-coupled or floating signal lines where polarity reversal may occur | Choose for RS-485, CAN FD, or audio lines needing bidirectional protection |
Compared with SMAJ13A-E3/57T and SMCJ13CAHE3_A/I, the SMCJ13AHE3_A/I delivers 3.75× higher surge power handling in the same SMC footprint and maintains unidirectional polarity essential for DC rail protection-making it optimal for automotive and industrial 12–24 V systems requiring robust load-dump immunity.

FAQ
What is the clamping voltage of SMCJ13AHE3_A/I at its rated peak pulse current?
The SMCJ13AHE3_A/I has a maximum clamping voltage (VC) of 21.5 V when subjected to its rated 10/1000 µs peak pulse current of 69.8 A. This value is measured under standardized test conditions per JEDEC and IEC 61000-4-5, and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCJ13AHE3_A/I maintains this clamping performance across its full operating temperature range of -55 °C to +150 °C.
Is SMCJ13AHE3_A/I qualified for automotive use?
Yes, SMCJ13AHE3_A/I is AEC-Q101 qualified, confirming compliance with stress tests including temperature cycling, high-temperature operating life, and mechanical shock specific to automotive electronics. The "HE3" suffix explicitly denotes AEC-Q101 qualification, and the device is rated for junction temperatures up to +150 °C-meeting requirements for under-hood and powertrain applications. SMCJ13AHE3_A/I is commonly deployed in engine control units and body control modules.
What does the "A/I" suffix mean in SMCJ13AHE3_A/I?
The "A/I" suffix in SMCJ13AHE3_A/I indicates packaging configuration: "A" denotes the revision code (Revision A per Vishay's ordering nomenclature), and "I" specifies 13-inch plastic tape-and-reel delivery containing 3500 units. This format supports high-volume automated SMT assembly. The base part SMCJ13AHE3 is identical electrically and mechanically; only packaging and reel size differ from the "A/H" variant (7-inch reel, 850 units).
How does SMCJ13AHE3_A/I compare to bidirectional TVS diodes like SMCJ13CAHE3_A/I?
SMCJ13AHE3_A/I is unidirectional and intended for DC line protection where polarity is fixed (e.g., 12 V supply to ground), offering asymmetric conduction: low forward voltage (~3.5 V at 100 A) and high reverse blocking. In contrast, SMCJ13CAHE3_A/I is bidirectional with symmetrical clamping in both directions, suited for AC or floating signals. Both share identical VWM (13 V), VBR, VC, and PPPM (1500 W), but SMCJ13AHE3_A/I cannot replace SMCJ13CAHE3_A/I in bidirectional applications without circuit redesign.
What PCB layout practices optimize SMCJ13AHE3_A/I performance?
To maximize SMCJ13AHE3_A/I effectiveness, mount it with minimum trace length between cathode and protected node and anode and ground plane-ideally using 8.0 mm × 8.0 mm copper pads per terminal as specified in the datasheet. Avoid vias in clamping paths; use solid internal ground planes. Thermal relief is unnecessary due to its 15 °C/W junction-to-lead thermal resistance. Ensure the cathode band aligns with schematic polarity to prevent reverse installation, which would render the SMCJ13AHE3_A/I nonfunctional.
