Product details
Overview
SMB10J16HE3/5B 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 a 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR), 26.0 V clamping voltage (VC) at 38.5 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform. It is AEC-Q101 qualified and used in automotive power supply input stages to protect downstream MOSFETs and microcontrollers.
For engineers reviewing the SMB10J16HE3/5B datasheet, SMB10J16HE3/5B pinout, SMB10J16HE3/5B application, or SMB10J16HE3/5B equivalent, key selection criteria include clamping performance under 10/1000 µs surges, AEC-Q101 qualification status, thermal resistance (RθJA = 72 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging an avalanche breakdown mechanism to limit transient overvoltages before they reach sensitive circuitry. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and repeatable breakdown behavior across temperature (-55 °C to +150 °C).
The device is optimized for fast response (sub-nanosecond) and low incremental surge resistance, enabling effective suppression of inductive switching spikes and ESD events. Its MSL Level 1 rating and matte tin-plated leads support robust reflow soldering per J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse operating voltage; defines safe DC bias range before conduction begins. |
| VBR (min/max) | 17.8 V / 19.7 V - Breakdown occurs within this range at 1.0 mA test current; ensures predictable turn-on threshold. |
| VC @ IPPM | 26.0 V at 38.5 A - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on protected ICs. |
| PPPM | 1000 W - Peak pulse power handling capability; enables survival of high-energy transients like ISO 7637-2 Pulse 1/2a/5a. |
| RθJA | 72 °C/W - Junction-to-ambient thermal resistance; requires ≥5.0 mm × 5.0 mm copper pad per terminal for rated power dissipation. |
| Qualification | AEC-Q101 qualified - Validated for automotive underhood and powertrain applications per stress test requirements. |
| Leakage ID | ≤1.0 µA at 16 V - Low reverse leakage preserves efficiency in always-on power rails and battery-sensitive systems. |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, molded plastic case with cathode band marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); terminals are matte tin-plated for solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-voltage return path; completes clamping loop during positive transients. |
| Cathode | Protected line input | Connected to the line being protected (e.g., 12 V battery rail); conducts avalanche current to anode during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| Uni-directional clamping | Enables integration into polarized DC rails without series blocking diodes; supports standard automotive battery protection topology. |
| AEC-Q101 qualification | Validates reliability for automotive power electronics including engine control units, body controllers, and ADAS power supplies. |
| MSL Level 1 (260 °C peak) | Permits single-reflow assembly without moisture sensitivity concerns; eliminates bake-out requirement in production. |
| Glass-passivated junction | Ensures long-term stability of VBR and leakage under thermal cycling and humidity exposure in harsh environments. |
| Low clamping ratio (VC/VBR ≈ 1.46) | Minimizes overvoltage margin between clamp level and protected IC's absolute maximum rating-critical for 24 V system designs. |
Applications
| Automotive Power Input Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-E3/5B | Same DO-214AA package and 16 V VWM, but not AEC-Q101 qualified; lower surge rating (600 W vs. 1000 W PPPM). | Restricted to commercial-grade industrial or consumer applications where automotive qualification is unnecessary. | Select when cost sensitivity outweighs automotive compliance and surge margin requirements. |
| 1.5SMC16A | Higher package thermal resistance (RθJA = 110 °C/W), same VWM and VC, but rated for 1500 W PPPM with larger SMC (DO-214AB) footprint. | Requires PCB redesign due to larger 7.11 mm × 6.22 mm outline; suited for higher-power legacy designs with available board space. | Choose only if existing layout accommodates SMC and higher power margin justifies added size and cost. |
Compared with SMBJ16A-E3/5B and 1.5SMC16A, SMB10J16HE3/5B uniquely balances AEC-Q101 qualification, 1000 W surge capacity, and compact SMB footprint-making it optimal for space-constrained automotive modules requiring validated reliability.

FAQ
What is the maximum clamping voltage of SMB10J16HE3/5B under a 10/1000 µs surge?
The SMB10J16HE3/5B clamps to a maximum of 26.0 V when subjected to its rated 38.5 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and confirmed in the Vishay datasheet revision 12-Nov-12, page 2. The clamping voltage directly determines the peak stress seen by downstream components protected by the SMB10J16HE3/5B.
Is SMB10J16HE3/5B suitable for automotive applications?
Yes, SMB10J16HE3/5B is AEC-Q101 qualified and explicitly intended for automotive use. Its qualification covers temperature cycling, humidity testing, and mechanical shock per the AEC standard. The HE3 suffix denotes AEC-Q101 compliance, and the device is deployed in engine control units, body control modules, and ADAS power supplies where transient immunity is critical. SMB10J16HE3/5B meets these requirements without derating at TJ = 150 °C.
What is the meaning of the 'HE3/5B' suffix in SMB10J16HE3/5B?
The 'HE3' suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. The '5B' denotes packaging in 13-inch diameter plastic tape and reel, with a base quantity of 3200 units per reel. This format supports high-volume SMT assembly and is specified in the Vishay ordering information table (page 3 of document 88422). SMB10J16HE3/5B is distinct from non-HE3 variants like SMB10J16A-E3/5B, which lack automotive qualification.
How does SMB10J16HE3/5B differ from SMBJ16A in practical design?
SMB10J16HE3/5B delivers 1000 W peak pulse power versus 600 W for SMBJ16A, enabling higher surge margin in ISO 7637-2 Pulse 5a testing. It also carries AEC-Q101 qualification (SMBJ16A does not) and uses a glass-passivated junction for improved long-term leakage stability. Both share the DO-214AA package, but SMB10J16HE3/5B's tighter VBR tolerance (17.8–19.7 V vs. 17.0–19.9 V) and lower RθJA (72 vs. 80 °C/W) make it preferable for thermally constrained automotive layouts.
What PCB layout guidance applies to SMB10J16HE3/5B for optimal thermal performance?
For rated 1000 W surge handling, Vishay specifies mounting SMB10J16HE3/5B on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. These pads must be connected to internal ground/power planes via multiple thermal vias to minimize RθJA. Avoid narrow traces between the SMB10J16HE3/5B and ground plane-direct low-inductance connection is essential to maintain clamping speed and prevent voltage overshoot during fast transients.
