Product details
Overview
SMB10J28-E3/52 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on power and signal lines. It features a 28 V stand-off voltage (VWM), 31.1–34.4 V breakdown voltage (VBR) at 1 mA, 45.4 V maximum clamping voltage (VC) at 22.0 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive power supply rails and industrial sensor interfaces.
For engineers reviewing the SMB10J28-E3/52 datasheet, SMB10J28-E3/52 pinout, SMB10J28-E3/52 application, or SMB10J28-E3/52 equivalent, key selection criteria include clamping performance under 22 A surge, unidirectional polarity with cathode band marking, AEC-Q101 qualification for automotive use, RoHS-compliant matte tin plating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds its breakdown threshold (31.1–34.4 V), it avalanches rapidly to divert surge current away from downstream ICs. Its glass-passivated junction ensures stable leakage (<1.0 µA at 28 V) and low incremental surge resistance, enabling consistent clamping at 45.4 V up to 22.0 A.
Thermally, it sustains operation from –55 °C to +150 °C junction temperature, with 72 °C/W junction-to-ambient thermal resistance (RθJA) on standard 0.2" × 0.2" pads and 20 °C/W junction-to-lead (RθJL). The device meets MSL Level 1 per J-STD-020 and passes JESD201 Class 1A whisker testing due to its E3 suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 28 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin for 24 V nominal systems. |
| VBR (min/max) | 31.1 V / 34.4 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering above system overvoltage thresholds. |
| VC @ IPPM | 45.4 V at 22.0 A - Clamped voltage during 10/1000 µs surge; limits stress on protected 3.3 V/5 V logic or MOSFET gate drivers. |
| PPPM | 1000 W - Peak pulse power handling capability; supports IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge immunity compliance. |
| ID @ VWM | <1.0 µA - Reverse leakage at rated stand-off; prevents excessive quiescent current in battery-powered sensor nodes. |
| TJ max. | +150 °C - Maximum junction temperature; enables deployment in under-hood automotive environments and industrial enclosures. |
| Package | DO-214AA (SMB) - Standard surface-mount outline with 0.220" body length; compatible with IPC-7351B footprint and reflow profiles up to 260 °C peak. |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with cathode band marking on one end; matte tin-plated leads solderable per J-STD-002 and JESD22-B102; polarity indicated by color band (cathode).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes shunt path during avalanche conduction. |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., 24 V rail); color band identifies this terminal for correct PCB orientation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - required for engine control and ADAS power domains. |
| Glass passivated junction | Stable VBR tolerance and low leakage across –55 °C to +150 °C; eliminates parameter drift in harsh thermal environments. |
| MSL Level 1 rating | Zero floor life limitation; supports indefinite dry pack storage and single-reflow assembly without baking. |
| 1000 W peak pulse power | Handles 22.0 A surges at 45.4 V clamping - sufficient for ISO 7637-2 Pulse 1/2b/5a and IEC 61000-4-5 combination wave tests. |
| RoHS-compliant E3 suffix | Meets JEDEC JESD201 Class 1A whisker resistance; eliminates tin whisker risk in long-life industrial control modules. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|

Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loops) of pressure/temperature sensors in factory automation. IC Role / Device Role / Timing Role: Bidirectional-capable unidirectional TVS placed across signal and return paths to absorb ESD and cable discharge events. Use Value: Sub-1 µA leakage at 28 V preserves loop accuracy; fast response avoids signal distortion during 8 kV contact ESD per IEC 61000-4-2. |
| Telecom DC Power Interface | Consumer Device USB Power Input |
|

IC Role / Device Role / Timing Role: Primary-level TVS mounted at board edge, upstream of POL converters and hot-swap controllers. Use Value: 1000 W PPPM withstands 10/1000 µs surges up to 4 kV; DO-214AA footprint allows dense layout near connectors. |
Use Scenario: Securing 5 V USB Type-A power input on smart home hubs against user-induced ESD and adapter transients. IC Role / Device Role / Timing Role: Unidirectional clamp referenced to system ground, placed immediately after USB connector. Use Value: 45.4 V clamping protects 5.5 V tolerant USB controller ICs; AEC-Q101 qualification ensures field longevity beyond consumer-grade expectations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ28A-E3/52 | Same VWM (28 V), identical DO-214AA package, but lower PPPM (600 W) and higher VC (48.4 V at 12.3 A). | Lower surge capacity suits cost-sensitive consumer designs; insufficient for automotive load dump per ISO 7637-2. | Select SMBJ28A-E3/52 only when peak surge current remains below 12.3 A and clamping voltage margin >48.4 V is acceptable. |
| SMCJ28A-E3/52 | Same VWM and VBR range, but larger DO-214AB (SMC) package; delivers 1500 W PPPM and lower VC (45.4 V at 33.0 A). | Higher power handling supports 12 V/24 V battery systems with extended surge duration; requires larger PCB area. | Choose SMCJ28A-E3/52 when system-level surge testing exceeds IEC 61000-4-5 Level 4 or when thermal derating below 75 °C is critical. |
Compared with SMBJ28A-E3/52, SMB10J28-E3/52 provides 67 % higher peak power and tighter clamping; versus SMCJ28A-E3/52, it trades 50 % lower surge rating for 30 % smaller footprint - making SMB10J28-E3/52 optimal for space-constrained AEC-Q101 automotive modules where 1000 W suffices.

FAQ
What is the clamping voltage of SMB10J28-E3/52 at its rated peak pulse current?
The SMB10J28-E3/52 has a maximum clamping voltage (VC) of 45.4 V at 22.0 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's Document Number 88422, ensuring predictable overvoltage limiting for downstream 3.3 V, 5 V, or 24 V-rated ICs in the SMB10J28-E3/52 protection path.
Is SMB10J28-E3/52 suitable for automotive applications?
Yes, SMB10J28-E3/52 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control, body electronics, and ADAS subsystems. Its construction - glass-passivated junction, MSL Level 1 rating, JESD201 Class 1A whisker resistance, and operation from –55 °C to +150 °C - meets stringent automotive reliability requirements defined in the SMB10J28-E3/52 datasheet.
What does the "E3/52" suffix mean in SMB10J28-E3/52?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin plating and JESD201 Class 1A whisker resistance; "/52" denotes packaging in 7" diameter plastic tape and reel with 750 units per reel. This configuration ensures compatibility with high-speed SMT pick-and-place equipment and satisfies environmental compliance mandates for the SMB10J28-E3/52.
How does SMB10J28-E3/52 differ from bi-directional variants like SMB8J28CA?
SMB10J28-E3/52 is unidirectional with cathode-band polarity and optimized for DC power line protection, whereas SMB8J28CA is bi-directional (no polarity marking) and intended for AC signal or data line protection. The SMB10J28-E3/52 offers 1000 W PPPM vs. 800 W for SMB8J28CA, reflecting its higher surge duty cycle suitability in the SMB10J28-E3/52 design.
What is the thermal resistance of SMB10J28-E3/52 under standard mounting conditions?
SMB10J28-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, and a junction-to-lead resistance (RθJL) of 20 °C/W. These values are specified in Vishay's thermal characteristics table and directly impact sustained power dissipation capability in the SMB10J28-E3/52 application.
