Product details
Overview
SMBJ5.0AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), and clamps transients to ≤9.2 V at 65.2 A, making it suitable for protecting MOSFET gates, microcontroller I/O, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the SMBJ5.0AHE3_A/H datasheet, SMBJ5.0AHE3_A/H pinout, SMBJ5.0AHE3_A/H application, or SMBJ5.0AHE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, low clamping voltage under surge, unidirectional polarity with cathode band marking, and SMB (DO-214AA) package compatibility with automated SMT assembly.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<800 µA at VWM), while the 100 °C/W junction-to-ambient thermal resistance requires appropriate PCB copper pad area (0.2" × 0.2") for rated 600 W pulse handling.
The device is rated for -55 °C to +150 °C operating junction temperature, supports 100 A non-repetitive forward surge (8.3 ms half-sine), and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its 0.057 %/°C VBR temperature coefficient enables predictable performance across thermal gradients in engine control units and power supply front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 5.0 V - Maximum continuous reverse voltage before significant leakage; sets minimum system operating margin. |
| VBR (Breakdown Voltage) | 6.4–7.07 V at 10 mA - Confirmed avalanche initiation range; ensures reliable turn-on before IC damage thresholds. |
| VC (Clamping Voltage) | ≤9.2 V at IPPM = 65.2 A - Actual voltage seen by protected circuit during 600 W transient; critical for 3.3 V/5 V logic survival. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 µs waveform) - Surge energy-handling capacity; validated for IEC 61000-4-5 Level 4 compliance. |
| ID (Reverse Leakage) | ≤800 µA at VWM - Low standby power loss; avoids loading sensitive reference or bias networks. |
| TJ max. | +150 °C - Enables placement near hot components (e.g., power MOSFETs, DC-DC inductors) without derating. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test requirements (HTOL, TC, HTRB); base suffix HE3 denotes qualification. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by a single band on the body end.
| Pin/Terminal | Circuit Role | Design Meaning |

| Anode (unmarked end) | Current entry point during forward conduction | Connected to ground or lower-potential rail in unidirectional clamp configuration. |
| Cathode (banded end) | Current exit point during reverse avalanche | Connected to protected line (e.g., 5 V rail, CAN_H); defines polarity and clamping direction. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Handles high-energy transients from inductive switching (e.g., solenoid drivers, relay coils) without failure. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/52 | Commercial-grade (non-AEC-Q101), same electrical specs and SMB package. | Lacks automotive qualification; suitable for consumer/industrial designs not requiring AEC validation. | Select when cost sensitivity outweighs automotive reliability requirements. |
| SMCJ5.0AHE3_A/H | Same AEC-Q101 qualification but in larger SMC (DO-214AB) package; 1500 W PPPM rating. | Higher power handling requires more PCB area; used where surge threat exceeds 600 W. | Choose when system-level testing reveals insufficient margin with SMBJ5.0AHE3_A/H's 600 W rating. |
Compared with SMBJ5.0AHE3_A/H, the SMBJ5.0A-E3/52 offers identical protection performance at lower cost but no automotive qualification, while the SMCJ5.0AHE3_A/H delivers 2.5× higher surge power in a larger footprint-enabling tiered design reuse across product families with varying threat levels.

FAQ
What is the clamping voltage of SMBJ5.0AHE3_A/H at its rated peak pulse current?
The SMBJ5.0AHE3_A/H has a maximum clamping voltage (VC) of 9.2 V when subjected to its peak pulse current (IPPM) of 65.2 A under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and guarantees that protected circuitry sees no more than 9.2 V during a full-rated 600 W transient event, making SMBJ5.0AHE3_A/H appropriate for safeguarding 5 V logic rails and interface ICs.
Is SMBJ5.0AHE3_A/H suitable for automotive applications?
Yes, SMBJ5.0AHE3_A/H is AEC-Q101 qualified, as confirmed by its "HE3" suffix and documentation in Vishay's 88392 datasheet. It undergoes stress testing for high-temperature operating life, temperature cycling, and humidity bias, enabling use in engine control units, body electronics, and ADAS subsystems where reliability under thermal and vibration stress is mandatory. The SMBJ5.0AHE3_A/H meets these requirements without derating up to +150 °C junction temperature.
How does the SMBJ5.0AHE3_A/H differ from the bidirectional SMBJ5.0CA variant?
The SMBJ5.0AHE3_A/H is unidirectional, with polarity marked by a cathode band and intended for DC rail protection where current flows only in one direction. In contrast, SMBJ5.0CA is bidirectional, lacks polarity marking, and protects AC or differential lines like RS-485 or CAN. Their breakdown voltages differ: SMBJ5.0AHE3_A/H has VBR = 6.4–7.07 V (reverse only), while SMBJ5.0CA has symmetric VBR ≈ 6.4–7.25 V in both directions. Select SMBJ5.0AHE3_A/H for 5 V supply clamping, not signal-line differential protection.
What PCB layout considerations apply to SMBJ5.0AHE3_A/H for optimal thermal and surge performance?
To achieve rated 600 W peak pulse power, SMBJ5.0AHE3_A/H must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. Smaller pads cause excessive junction temperature rise and premature failure. Additionally, short, wide traces to ground minimize inductance and preserve clamping speed; avoid vias in the main surge path. The SMBJ5.0AHE3_A/H thermal resistance (RθJA = 100 °C/W) assumes this layout-deviations require derating per Figure 2 in document 88392.
Does SMBJ5.0AHE3_A/H meet RoHS and halogen-free requirements?
Yes, SMBJ5.0AHE3_A/H is RoHS-compliant and AEC-Q101 qualified, as indicated by the "HE3" suffix per Vishay's ordering nomenclature. It contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE, and complies with EU Directive 2011/65/EU. While not halogen-free (that requires "HM3" suffix), SMBJ5.0AHE3_A/H uses brominated flame-retardant molding compound meeting UL 94 V-0, and its matte tin plating satisfies JESD 201 Class 2 whisker resistance requirements.
