Product details
Overview
SMBJ6.0-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), clamping voltage of 10.3 V at 58.3 A, and operates across -55 °C to +150 °C junction temperature.
For engineers reviewing the SMBJ6.0-E3/52 datasheet, SMBJ6.0-E3/52 pinout, SMBJ6.0-E3/52 application, or SMBJ6.0-E3/52 equivalent, key selection considerations include its unidirectional polarity, 10.3 V clamping performance under 58.3 A surge, RoHS-compliant matte tin-plated leads, MSL Level 1 moisture sensitivity, and suitability for IC-level protection in automotive, industrial, and telecom signal lines.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below VWM = 6.0 V and rapidly transitions to low-impedance conduction once VBR (min 6.67 V) is exceeded. Its glass-passivated junction ensures stable avalanche characteristics and fast response time (<1 ns), while the SMB package provides thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead).
The device complies with ANSI/IEEE C62.35 for surge protection and meets UL 497B recognition (QVGQ2). It is rated for repetitive 10/1000 µs waveform pulses at 0.01% duty cycle, with derating above 25 °C per Figure 2 and validated surge current handling up to 58.3 A at TA = 25 °C on 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum reverse working voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients |
| VC @ IPPM | 10.3 V at 58.3 A - Clamped voltage during 600 W surge; determines protected circuit's maximum stress level |
| PPPM | 600 W (10/1000 µs) - Peak transient energy absorption capability; validates robustness against common lightning/inductive spikes |
| ID @ VWM | 800 µA max - Low reverse leakage at rated stand-off; minimizes standby power loss and signal distortion |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry (unidirectional) | Connected to system ground or low-side reference; enables conduction when cathode voltage exceeds anode by ≥VBR |
| Cathode | Reverse-biased terminal (marked with band) | Connected to protected line; absorbs positive transients by clamping to VC relative to anode |
Key Features

| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), improving protection fidelity |
| MSL Level 1 (260 °C peak reflow) | Enables single-pass lead-free reflow assembly without moisture-induced popcorn failure |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-E3/52 | Same electrical specs and package; identical marking code KG and VBR range (6.67–7.37 V); differs only in reel packaging (52 = 750 pcs/reel) | No functional difference; both rated for commercial use with same thermal and surge performance | Select SMBJ6.0-E3/52 for standard 7" tape-and-reel delivery; SMBJ6.0A-E3/52 is functionally interchangeable but may reflect legacy ordering syntax |
| SMCJ6.0A-E3/52 | Higher 1500 W PPPM, larger SMC (DO-214AB) package (7.11 mm × 6.22 mm), higher VC = 10.5 V at 143 A, RθJA = 35 °C/W | Better suited for higher-energy surges (e.g., AC mains coupling) but requires larger PCB area and different pad layout | Choose SMCJ6.0A-E3/52 only if 600 W is insufficient and board space allows SMC footprint; not a drop-in replacement due to size and thermal profile differences |
Compared with SMBJ6.0A-E3/52, SMBJ6.0-E3/52 offers identical protection performance in the same SMB package but reflects Vishay's standardized base-P/N naming convention; versus SMCJ6.0A-E3/52, it trades surge capacity for compactness and lower thermal resistance in space-constrained designs.

FAQ
What is the clamping voltage of SMBJ6.0-E3/52 and how is it measured?
The SMBJ6.0-E3/52 has a maximum clamping voltage (VC) of 10.3 V, measured at its peak pulse current (IPPM) of 58.3 A using a standardized 10/1000 µs double-exponential surge waveform. This value is guaranteed per Vishay's datasheet Document Number 88392 and reflects worst-case voltage seen by protected circuitry during a 600 W transient event.
Is SMBJ6.0-E3/52 suitable for automotive applications?
SMBJ6.0-E3/52 is rated for commercial temperature range (-55 °C to +150 °C) and RoHS compliance but is not AEC-Q101 qualified. For automotive applications requiring qualification, select the HE3-suffixed variant (e.g., SMBJ6.0HE3), which carries the AEC-Q101 certification while retaining identical electrical parameters and SMB package dimensions.
How does the breakdown voltage range of SMBJ6.0-E3/52 affect circuit design?
The SMBJ6.0-E3/52 exhibits a VBR range of 6.67 V to 7.37 V at 10 mA test current. Designers must ensure the protected circuit's maximum operating voltage remains below 6.67 V to avoid premature conduction, while verifying that the clamping voltage (10.3 V) stays within the absolute maximum rating of downstream components.
What is the meaning of the "-E3/52" suffix in SMBJ6.0-E3/52?
The "E3" denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads; "/52" specifies packaging in 7-inch diameter plastic tape-and-reel containing 750 units. This suffix confirms compliance with JEDEC MSL Level 1 and JESD 201 Class 2 whisker resistance, enabling standard lead-free reflow processing.
Can SMBJ6.0-E3/52 be used in bidirectional configurations?
No - SMBJ6.0-E3/52 is a unidirectional TVS diode, identified by its cathode band marking. For bidirectional operation, use the CA-suffixed variant (e.g., SMBJ6.0CA), which provides symmetrical clamping in both polarities and omits the polarity band. The electrical characteristics of SMBJ6.0CA differ, including doubled ID limit for VWM ≤10 V.
