Product details
Overview
SMB10J6.0-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 DC power rails and signal lines. It features 6.0 V stand-off voltage (VWM), 1000 W peak pulse power (10/1000 µs), 10.3 V maximum clamping voltage at 97.1 A peak surge current, and AEC-Q101 qualification for automotive electronics.
For engineers reviewing the SMB10J6.0-E3/52 datasheet, SMB10J6.0-E3/52 pinout, SMB10J6.0-E3/52 application, or SMB10J6.0-E3/52 equivalent, key selection criteria include clamping performance under 100 A surge, thermal resistance (RθJA = 72 °C/W), 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 unidirectional avalanche clamp, triggered when reverse voltage exceeds its 6.67–7.37 V breakdown range (VBR at 10 mA). Its glass-passivated junction ensures stable leakage (<1000 µA at VWM) and fast response (<1 ns), critical for protecting MOSFET gates and microcontroller I/O against ESD and load-switching transients.
Rated for -55 °C to +150 °C junction temperature, it delivers 100 W steady-state power dissipation and withstands 100 A non-repetitive forward surge (8.3 ms half-sine). The DO-214AA package supports MSL Level 1 handling and meets UL 94 V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; sets upper limit for protected circuit's normal DC rail. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown threshold range; ensures reliable turn-on without premature conduction. |
| VC @ IPPM | 10.3 V at 97.1 A - Measured clamping voltage during 1000 W surge; defines worst-case overvoltage seen by downstream ICs. |
| PPPM | 1000 W (10/1000 µs waveform) - Peak surge energy absorption capacity; validates suitability for ISO 7637-2 Pulse 1/2a/5a automotive transients. |
| IFSM | 100 A (8.3 ms half-sine) - Forward surge rating; enables robust protection of power supply inputs against inductive kickback. |
| RθJA | 72 °C/W - Junction-to-ambient thermal resistance; determines required PCB copper area (0.2" × 0.2") for safe 100 W dissipation. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A114. |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, low-profile case with cathode band marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); terminals are matte tin-plated for J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., GND or return path); conducts during positive transients when used in reverse-biased protection configuration. |
| Cathode | Reverse-bias terminal | Marked with color band; connected to protected line (e.g., 5 V rail); avalanches into conduction when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Low incremental surge resistance | Enables tighter clamping (10.3 V at 97.1 A), reducing stress on downstream MOSFETs and logic ICs during fast transients. |
| Glass passivated chip junction | Ensures stable VBR tolerance (±5%) and <1000 µA leakage at 6.0 V, critical for battery-powered sensor nodes. |
| MSL Level 1 (260 °C peak) | Supports lead-free reflow without moisture-induced popcorning; eliminates pre-bake requirement for high-volume SMT assembly. |
| RoHS-compliant & whisker-tested (JESD201 Class 1A) | Meets global environmental regulations and prevents tin whisker growth in long-life automotive modules (>15 yr field life). |
| UL 94 V-0 molding compound | Provides flame-retardant housing essential for under-hood ECUs and industrial control cabinets meeting IEC 62368-1. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-E3/52 | Same DO-214AA package and 6.0 V VWM, but rated for 600 W PPPM (vs. 1000 W); lower IPPM (58.8 A) and higher VC (10.5 V). | Acceptable for consumer-grade 5 V rails with lower surge exposure (e.g., USB peripherals), but insufficient for automotive load-dump compliance. | Select SMB10J6.0-E3/52 when 1000 W surge immunity is mandatory; choose SMBJ6.0A-E3/52 only for cost-sensitive, non-automotive designs with verified lower threat levels. |
| 1.5SMC6.0A | DO-214AB (SMC) package (larger footprint), same 6.0 V VWM, 1000 W rating, but higher RθJA (50 °C/W) and no AEC-Q101 qualification. | Suitable for industrial power supplies where board space allows larger SMC package, but not approved for automotive use cases requiring AEC-Q101. | Prefer SMB10J6.0-E3/52 for AEC-Q101-compliant automotive modules; use 1.5SMC6.0A only when thermal budget permits larger package and automotive qualification is unnecessary. |
Compared with SMBJ6.0A-E3/52 and 1.5SMC6.0A, SMB10J6.0-E3/52 uniquely combines AEC-Q101 qualification, 1000 W surge capability in compact DO-214AA, and 72 °C/W thermal resistance-making it the only choice for space-constrained, high-reliability automotive power rail protection.

FAQ
What is the clamping voltage of SMB10J6.0-E3/52 at its rated peak pulse current?
The SMB10J6.0-E3/52 has a maximum clamping voltage (VC) of 10.3 V when subjected to its rated peak pulse current of 97.1 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 standards and defines the upper voltage limit imposed on protected circuits during surge events. The SMB10J6.0-E3/52 maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C), making it suitable for under-hood automotive applications.
Is SMB10J6.0-E3/52 suitable for bi-directional transient protection?
No, SMB10J6.0-E3/52 is a unidirectional TVS diode, indicated by the "J" (not "JC") suffix and presence of a cathode band marking. It conducts only in reverse bias above VBR and blocks forward current up to 3.5 V at 50 A. For bi-directional protection-such as AC signal lines or differential buses-Vishay's SMB8J6.0CA-E3/52 (800 W, symmetrical clamping) must be used instead. The SMB10J6.0-E3/52 is optimized for DC rail protection where polarity is fixed.
What PCB pad layout is required to achieve the rated 1000 W peak pulse power for SMB10J6.0-E3/52?
To achieve the full 1000 W peak pulse power rating, SMB10J6.0-E3/52 must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Vishay document 88422. Smaller pads increase thermal impedance, derating both peak power and steady-state dissipation. The DO-214AA package's thermal resistance (RθJA = 72 °C/W) is validated only with this layout; reducing pad size to 1.0 mm², for example, can raise RθJA above 120 °C/W and risk thermal runaway during repeated surges.
Does SMB10J6.0-E3/52 meet automotive qualification standards?
Yes, SMB10J6.0-E3/52 is AEC-Q101 qualified, as confirmed by Vishay's documentation (document 88422, revision 12-Nov-12). This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD (HBM ≥ 8 kV), validating its reliability for automotive powertrain, body, and chassis modules. The "HE3" variant (e.g., SMB10J6.0AHE3/52) denotes the AEC-Q101 version; however, the "E3/52" suffix in SMB10J6.0-E3/52 also indicates commercial-grade RoHS compliance with AEC-Q101 qualification per Vishay's ordering matrix.
How does the glass passivation in SMB10J6.0-E3/52 improve long-term reliability?
The glass passivated junction in SMB10J6.0-E3/52 provides superior environmental stability versus silicon nitride or polymer passivation, minimizing parameter drift over time and temperature. It reduces reverse leakage current to <1000 µA at 6.0 V VWM across -55 °C to +150 °C, prevents moisture ingress that causes corrosion-related failure, and maintains tight VBR tolerance (6.67–7.37 V) after 1000 hours of high-temperature operating life testing. This directly extends field life in harsh environments like automotive under-hood or industrial motor drives where SMB10J6.0-E3/52 is deployed.
