Product details
Overview
SMB8J16CAHE3_A/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on signal and power lines. It features a 16 V stand-off voltage (VWM), 26.0 V maximum clamping voltage (VC) at 30.8 A peak pulse current (IPPM), and 800 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMB8J16CAHE3_A/I datasheet, SMB8J16CAHE3_A/I pinout, SMB8J16CAHE3_A/I application, or SMB8J16CAHE3_A/I equivalent, this AEC-Q101 qualified TVS offers verified bidirectional clamping performance, low leakage (<1.0 μA at VWM), and MSL Level 1 moisture sensitivity - critical for automotive-grade PCB layout and long-term reliability validation.
Technical Context
This device operates as a voltage-clamped crowbar during transients: when reverse voltage exceeds its 17.8–19.7 V breakdown range (VBR at 1.0 mA), it avalanches to limit downstream voltage to ≤26.0 V at 30.8 A. Its glass-passivated junction ensures stable VBR tolerance and fast response (<1 ns).
Thermally, it sustains 150 °C max junction temperature with RθJA = 72 °C/W and RθJL = 20 °C/W, enabling reliable operation on standard 0.2" × 0.2" copper pads. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification per stress test conditions including temperature cycling, HTRB, and ESD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before conduction begins; defines safe signal line bias margin. |
| VBR (min/max) | 17.8 V / 19.7 V at 1.0 mA - precise avalanche onset window ensuring predictable turn-on without premature leakage. |
| VC @ IPPM | 26.0 V at 30.8 A - clamping voltage under full 800 W surge; limits protected IC voltage stress to safe levels. |
| PPPM | 800 W (10/1000 μs) - energy-handling capacity sufficient for ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | <1.0 μA - ultra-low reverse leakage preserves signal integrity and battery life in always-on circuits. |
| TJ max. | +150 °C - supports under-hood automotive environments and industrial enclosures without derating. |
| Package | SMB (DO-214AA) - surface-mount footprint compatible with automated assembly; 2.20 mm × 3.94 mm × 1.95 mm body. |
Pinout & Package
Two-terminal bidirectional device in SMB (DO-214AA) package: no polarity marking; symmetrical terminals function identically for AC or differential line protection. Mounting requires 0.086" × 0.220" (2.18 mm × 5.59 mm) minimum pad layout per terminal per Vishay spec.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals serve as interchangeable surge current entry/exit points; no cathode band marking required for bidirectional operation. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CAHE3_A/I | Same VWM (16 V), but lower PPPM (600 W) and higher VC (28.0 V); unidirectional variant not applicable. | Limited to lower-energy surges (IEC 61000-4-5 Level 3); unsuitable for automotive load dump where 800 W is required. | Select only if system-level surge testing confirms 600 W sufficiency and cost optimization is prioritized. |
| SMCJ16CAHE3_A/I | Same VWM and bidirectionality, but larger SMC (DO-214AB) package; higher PPPM (1500 W) and lower VC (24.4 V). | Better suited for high-power industrial motor drives; requires larger PCB area and different pad layout. | Choose when higher surge margin is needed and board space allows SMC footprint; not drop-in compatible. |

FAQ
What is the clamping voltage of SMB8J16CAHE3_A/I at its rated peak pulse current?
The SMB8J16CAHE3_A/I exhibits a maximum clamping voltage (VC) of 26.0 V when subjected to its rated peak pulse current (IPPM) of 30.8 A using the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's datasheet revision 09-Jan-2024, ensuring predictable overvoltage limiting for downstream ICs in real-world surge events.
Is SMB8J16CAHE3_A/I suitable for automotive applications?
Yes, SMB8J16CAHE3_A/I is explicitly AEC-Q101 qualified, with test records covering HTOL, temperature cycling, HTRB, and ESD per JESD22-A114. Its HE3 suffix denotes RoHS compliance and automotive qualification, and it is referenced in Vishay's documentation for use in engine control units, ADAS sensor interfaces, and infotainment power supplies - making SMB8J16CAHE3_A/I appropriate for under-hood and cabin applications.
How does the bidirectional configuration of SMB8J16CAHE3_A/I affect its circuit implementation?
The SMB8J16CAHE3_A/I has no polarity marking and functions identically in either orientation, enabling direct placement across AC-coupled lines, differential buses (e.g., RS-485, CAN), or ungrounded power rails. Unlike unidirectional TVS diodes, SMB8J16CAHE3_A/I clamps both positive and negative transients without requiring ground reference - simplifying layout and eliminating risk of incorrect orientation during assembly.
What is the maximum operating temperature for SMB8J16CAHE3_A/I?
The SMB8J16CAHE3_A/I supports an operating junction temperature range of –55 °C to +150 °C, with thermal resistance values of RθJA = 72 °C/W and RθJL = 20 °C/W. This allows sustained operation in high-ambient environments such as automotive engine compartments or sealed industrial enclosures, provided PCB copper pad layout meets Vishay's recommended 0.2" × 0.2" dimensions per terminal.
Does SMB8J16CAHE3_A/I require special handling during PCB assembly?
No special handling beyond standard MSL Level 1 requirements is needed for SMB8J16CAHE3_A/I. It is rated for peak reflow temperatures up to 260 °C per J-STD-020, compatible with lead-free soldering processes without pre-baking. Matte tin-plated leads meet J-STD-002 and JESD 22-B102 for solderability, and whisker resistance is certified to JESD 201 Class 2 - confirming robust manufacturability in high-volume SMT lines.
