Product details
Overview
SMB10J6.5HE3/52 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 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR at 10 mA), 11.2 V maximum clamping voltage (VC) at 89.3 A peak pulse current, and 1000 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the SMB10J6.5HE3/52 datasheet, SMB10J6.5HE3/52 pinout, SMB10J6.5HE3/52 application, or SMB10J6.5HE3/52 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 72 °C/W), RoHS-compliant HE3 suffix marking, and design-meaning context for clamping performance, surge robustness, and PCB layout implications.
Technical Context
This TVS diode operates as a shunt-clamping device: under normal bias it presents high impedance (<1 µA leakage at 6.5 V), then rapidly avalanches to limit transient overvoltage to ≤11.2 V during 10/1000 µs surges up to 89.3 A. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance, critical for protecting downstream MOSFET gates and microcontroller I/O pins.
The SMB10J6.5HE3/52 is AEC-Q101 qualified and rated for -55 °C to +150 °C junction operation. Its DO-214AA package provides 72 °C/W junction-to-ambient thermal resistance when mounted on 5.0 mm × 5.0 mm copper pads - enabling reliable power dissipation in space-constrained automotive modules without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - Maximum continuous reverse operating voltage; must exceed system nominal rail (e.g., 5 V or 6 V bus) to avoid leakage-induced power loss. |
| VBR (min/max) | 7.22 V / 7.98 V at 10 mA - Confirmed avalanche onset range; ensures consistent triggering across temperature and unit variation. |
| VC @ IPPM | 11.2 V at 89.3 A - Clamped voltage seen by protected IC during worst-case surge; defines minimum required voltage margin for downstream components. |
| PPPM | 1000 W (10/1000 µs) - Sustains single high-energy transients (e.g., ISO 7637-2 Pulse 1/2a/5a) without failure. |
| IFSM | 100 A (8.3 ms half-sine) - Withstands repetitive load-dump events in 12 V automotive systems without bond-wire fusing. |
| TJ max | 150 °C - Enables operation in under-hood ECUs and motor control units where ambient exceeds 105 °C. |
| RθJA | 72 °C/W - Requires ≥5.0 mm × 5.0 mm Cu pad per terminal for thermal compliance; insufficient copper causes premature thermal runaway. |
Pinout & Package
DO-214AA (SMB) surface-mount package: cathode indicated by black band on one end; anode and cathode terminals are axially aligned along the body length. Standardized footprint compatible with automated pick-and-place and reflow soldering per J-STD-020 MSL Level 1 (260 °C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Low-side reference node | Connected to ground or low-impedance return path; must be routed with minimal inductance to preserve clamping speed. |
| Cathode (banded end) | Protected line input | Connected to line under protection (e.g., battery feed); polarity-sensitive - reverse connection disables protection. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive powertrain and chassis applications per stress test requirements (HTOL, TC, HAST, etc.). |
| Glass-passivated junction | Eliminates moisture sensitivity and ensures long-term VBR stability under thermal cycling and humidity exposure. |
| MSL Level 1 rating | Zero floor life limitation - can be stored indefinitely before reflow; no baking required prior to assembly. |
| Matte tin-plated leads | Complies with JESD 22-B102 solderability and JESD 201 Class 2 whisker resistance - suitable for lead-free reflow. |
| UL 94 V-0 molding compound | Self-extinguishing encapsulant prevents flame propagation in high-density PCB assemblies. |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamp |
|---|---|
|
Use Scenario: 12 V battery-fed ECU power rail exposed to load dump (ISO 7637-2 Pulse 5a) and jump-start transients. IC Role / Device Role / Timing Role: Shunt-clamping TVS placed upstream of DC/DC converter input to clamp surges before they reach regulator ICs. Use Value: Limits transient voltage to ≤11.2 V, preserving 16 V-rated input capacitors and preventing regulator latch-up or damage. |
Use Scenario: Analog output line (0–10 V) from pressure sensor in factory automation PLC module. IC Role / Device Role / Timing Role: Bidirectional protection not applicable; SMB10J6.5HE3/52 used unidirectionally to clamp negative-going ESD (IEC 61000-4-2) on grounded-signal configuration. Use Value: Sub-100 ns response time clamps ±8 kV contact discharge to <12 V, preventing op-amp input stage breakdown. |
| Consumer USB Port Overvoltage Guard | Telecom DC Feeder Surge Suppression |
|
Use Scenario: VBUS line in USB 2.0 host port subjected to hot-plug induced ringing and external ESD. IC Role / Device Role / Timing Role: Unidirectional TVS referenced to GND, placed between USB connector and USB controller's VBUS pin. Use Value: 6.5 V VWM allows full 5 V ±5% operation while clamping 15 kV air discharge to ≤11.2 V - within USB PHY tolerance. |
Use Scenario: -48 V DC telecom power feed entering remote radio head enclosure. IC Role / Device Role / Timing Role: Reverse-connected SMB10J6.5HE3/52 (cathode to -48 V, anode to GND) clamps positive surges toward GND. Use Value: 1000 W PPPM handles lightning-induced surges (IEC 61000-4-5, 2 Ω source) without degradation over 1000+ events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5A-E3/52 | Same VWM, VBR, VC, and package; differs only in RoHS/commercial grade (E3) vs. AEC-Q101 (HE3) qualification. | Not qualified for automotive under-hood use; acceptable for industrial or consumer applications with lower reliability requirements. | Select SMBJ6.5A-E3/52 if AEC-Q101 is not mandated and cost optimization is prioritized. |
| 1.5SMC6.5A | Same electrical specs but in larger DO-214AB (SMC) package; RθJA = 30 °C/W vs. 72 °C/W - enables higher average power handling. | Requires larger PCB area; better suited for high-repetition-rate surge environments (e.g., motor drive feedback loops). | Choose 1.5SMC6.5A when thermal budget is constrained and board space permits larger footprint. |
Compared with SMBJ6.5A-E3/52, SMB10J6.5HE3/52 adds AEC-Q101 validation for automotive deployment; compared with 1.5SMC6.5A, it trades thermal performance for compact DO-214AA size - making it optimal for space-limited, high-reliability 12 V systems.

FAQ
What is the clamping voltage of SMB10J6.5HE3/52 and how is it measured?
The SMB10J6.5HE3/52 has a maximum clamping voltage (VC) of 11.2 V at 89.3 A peak pulse current, tested with a 10/1000 µs waveform per ANSI/IEEE C62.35. This value represents the actual voltage imposed on the protected circuit during worst-case surge conditions - confirmed via standardized transient generator testing, not calculated or simulated.
Is SMB10J6.5HE3/52 suitable for bidirectional transient protection?
No - SMB10J6.5HE3/52 is a unidirectional TVS diode, identified by its cathode band marking and specified VBR/VC values for reverse-bias operation only. For bidirectional protection, Vishay offers the SMB8J6.5CA variant, which has symmetric breakdown in both polarities and no polarity marking.
What does the "HE3" suffix indicate in SMB10J6.5HE3/52?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes SMB10J6.5HE3/52 from commercial-grade "E3" variants (e.g., SMBJ6.5A-E3/52) and confirms suitability for automotive under-hood applications per stress-test requirements.
How much PCB copper area is required for SMB10J6.5HE3/52 thermal management?
SMB10J6.5HE3/52 requires minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads on both anode and cathode terminals to achieve the specified RθJA of 72 °C/W. Reducing pad size increases junction temperature during surge events and may cause premature thermal failure - verified per Figure 2 derating curves in the Vishay datasheet 88422.
Can SMB10J6.5HE3/52 replace SMBJ6.5A-E3/52 in an existing design?
Yes - SMB10J6.5HE3/52 is pin-identical and electrically equivalent to SMBJ6.5A-E3/52, differing only in AEC-Q101 qualification and whisker test class. No PCB changes are needed; however, the HE3 version adds automotive reliability assurance without altering layout, routing, or bill-of-materials footprint.
