Product details
Overview
SMBJ5.0-E3/52 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 industrial power supplies.
For engineers reviewing the SMBJ5.0-E3/52 datasheet, SMBJ5.0-E3/52 pinout, SMBJ5.0-E3/52 application, or SMBJ5.0-E3/52 equivalent, key selection criteria include its unidirectional polarity, SMB (DO-214AA) package compatibility with automated SMT placement, low 0.057 %/°C VBR temperature coefficient, and AEC-Q101 qualification readiness via HE3 suffix variants.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below 5.0 V and rapidly avalanches above its 6.4–7.07 V breakdown threshold to divert surge current away from protected circuitry. Its glass-passivated junction ensures stable leakage (<800 µA at VWM) and repeatable clamping performance under repetitive transients.
The SMBJ5.0-E3/52 delivers 600 W peak pulse power handling with a 10/1000 µs waveform and exhibits very fast response time (<1 ns), low incremental surge resistance, and thermal resistance of 100 °C/W (junction-to-ambient) on standard 5.0 mm × 5.0 mm copper pads - enabling robust protection without external heatsinking in space-constrained designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before significant leakage begins; defines safe DC rail margin. |
| VBR @ IT = 10 mA | 6.4–7.07 V - Breakdown onset range; ensures reliable triggering above system nominal voltage with margin. |
| VC @ IPPM = 65.2 A | ≤9.2 V - Clamped voltage during 600 W transient; determines maximum stress imposed on downstream ICs. |
| IPPM | 65.2 A - Peak surge current supported by 10/1000 µs waveform; defines single-event energy absorption capability. |
| PPPM | 600 W - Peak pulse power rating; sets upper limit for transient energy dissipation without failure. |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in high-ambient industrial environments. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height; compatible with J-STD-020 MSL Level 1 reflow. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional polarity with cathode band marking. Matte tin-plated leads, RoHS-compliant (E3 suffix), rated for 260 °C peak reflow per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; completes conduction path during reverse-biased transient clamping. |
| Cathode | High-side connection point | Connected to protected line (e.g., +5 V rail); avalanche conduction occurs when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables protection against IEC 61000-4-5 Level 3 (1 kV/2 Ω) surges without derating in typical PCB layouts. |
| Clamping voltage ≤9.2 V at 65.2 A | Keeps protected 5 V logic circuits (e.g., MCU GPIO, UART lines) safely below absolute maximum ratings during transients. |
| Low VBR tempco: 0.057 %/°C | Minimizes drift in breakdown threshold across -55 °C to +150 °C ambient, ensuring consistent protection in automotive/industrial environments. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking, reducing manufacturing overhead and handling risk. |
| Glass-passivated junction | Provides stable leakage (<800 µA), high reliability, and resistance to humidity-induced degradation in harsh conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0AHE3_B/H | AEC-Q101 qualified; identical electrical specs but validated for automotive-grade reliability and extended temperature cycling. | Required for automotive body control modules, infotainment power rails, and ADAS sensor interfaces where qualification is mandatory. | Select when automotive qualification is required; otherwise SMBJ5.0-E3/52 suffices for commercial/industrial use. |
| SMCJ5.0A-E3/57 | Larger SMC (DO-214AB) package; same VWM/VBR, but higher 1500 W PPPM and 136 A IPPM. | Better suited for high-energy industrial motor drives or telecom power systems where >600 W surge margin is needed. | Choose only if board layout allows larger footprint and higher surge energy must be absorbed without clamping voltage increase. |
Compared with SMBJ5.0AHE3_B/H, the SMBJ5.0-E3/52 offers identical clamping and standoff performance at lower cost and qualification overhead; compared with SMCJ5.0A-E3/57, it provides space-optimized protection with adequate 600 W rating for most 5 V interface applications.

FAQ
What is the maximum clamping voltage of SMBJ5.0-E3/52 under surge conditions?
The SMBJ5.0-E3/52 clamps to a maximum of 9.2 V when subjected to its rated peak pulse current of 65.2 A (10/1000 µs waveform). This value is measured per JEDEC standards and guarantees that protected circuitry sees no more than 9.2 V during transient events, making SMBJ5.0-E3/52 appropriate for safeguarding 5 V logic systems where absolute maximum ratings are tight.
Is SMBJ5.0-E3/52 RoHS-compliant and lead-free?
Yes, SMBJ5.0-E3/52 is RoHS-compliant and lead-free, as indicated by the "E3" suffix per Vishay's ordering nomenclature. It uses matte tin-plated terminals and meets JESD 201 Class 2 whisker resistance requirements, with full compliance documented in Vishay's material declarations and UL recognition file E136766.
Can SMBJ5.0-E3/52 be used in bidirectional configurations?
No, SMBJ5.0-E3/52 is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional operation, Vishay specifies the CA-suffixed variant (e.g., SMBJ5.0CA), which has symmetrical breakdown in both directions and no polarity marking. Using SMBJ5.0-E3/52 in reverse-biased AC applications would result in forward conduction and failure.
What is the thermal resistance of SMBJ5.0-E3/52, and how does it affect layout?
The SMBJ5.0-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperatures under repetitive surges, designers must provide adequate copper area and avoid excessive trace length - undersized pads will raise RθJA and risk thermal runaway during sustained transient activity.
Does SMBJ5.0-E3/52 meet automotive qualification standards?
The base SMBJ5.0-E3/52 is commercial-grade and not AEC-Q101 qualified. However, Vishay offers the functionally identical SMBJ5.0AHE3_B/H variant, which carries full AEC-Q101 qualification for automotive applications. Engineers selecting SMBJ5.0-E3/52 should verify whether their end equipment requires automotive qualification - if so, SMBJ5.0AHE3_B/H is the compliant drop-in alternative.
