Product details
Overview
SMBJ16CAHE3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), and clamps to ≤26.0 V at 23.1 A peak surge current - used to protect MOSFETs, ICs, and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the SMBJ16CAHE3_B/H datasheet, SMBJ16CAHE3_B/H pinout, SMBJ16CAHE3_B/H application, or SMBJ16CAHE3_B/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, 26.0 V maximum clamping voltage at rated IPPM, thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1.0 μA at VWM), while the 10/1000 μs waveform rating reflects real-world lightning and inductive-switching surge immunity.
The device is qualified to AEC-Q101 for automotive applications and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its 150 °C maximum junction temperature and 20 °C/W junction-to-lead thermal resistance support reliable operation under repetitive surge conditions when mounted per recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 17.8 V / 19.7 V at IT = 1 mA - tight breakdown window ensures predictable turn-on threshold |
| VC @ IPPM | 26.0 V at 23.1 A - clamping voltage defines worst-case stress on protected downstream circuitry |
| PPPM | 600 W (10/1000 μs) - peak transient energy absorption capacity under standardized surge waveform |
| ID @ VWM | ≤1.0 μA - ultra-low leakage preserves signal integrity and battery life in always-on circuits |
| TJ max | +150 °C - enables use in under-hood automotive and high-temperature industrial environments |
| RθJA | 100 °C/W - thermal performance baseline for PCB layout planning with standard 0.2" × 0.2" copper pads |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional - no polarity marking; symmetrical two-terminal construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (either direction) | One terminal of bidirectional PN junction; accepts surge current regardless of polarity |
| Cathode | Transient current exit (either direction) | Second terminal of bidirectional PN junction; completes low-impedance path during clamping |
Key Features
| Feature | Design Value |

| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth, 2 kV line-line) when properly laid out |
| Low clamping ratio (VC/VBR ≈ 1.46) | Minimizes overvoltage stress on protected ICs compared to higher-ratio suppressors |
| MSL Level 1, 260 °C peak | Compatible with standard lead-free reflow profiles without moisture sensitivity concerns |
| Glass passivated junction | Ensures long-term stability of VBR and leakage across temperature and humidity variations |
Applications
| Industrial Motor Control | Automotive Body Control Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA-E3/52 | Same electrical specs, RoHS-compliant commercial grade (non-AEC-Q101) | Lacks automotive qualification; suitable for industrial/commercial only | Select when AEC-Q101 is not required and cost optimization is prioritized |
| SAC16-03 | Same VWM (16 V), lower PPPM (400 W), different package (SOD-323) | Lower surge handling; limited to low-energy ESD, not lightning-level transients | Choose only for space-constrained consumer designs with verified <400 W threat levels |
Compared with SMBJ16CAHE3_B/H, SMBJ16CA-E3/52 offers identical clamping and leakage but lacks automotive qualification, while SAC16-03 trades surge robustness for footprint reduction - making SMBJ16CAHE3_B/H the sole choice for AEC-Q101-compliant 600 W bidirectional protection in SMB package.

FAQ
What does the "CA" suffix indicate in SMBJ16CAHE3_B/H?
The "CA" suffix denotes a bidirectional configuration - meaning SMBJ16CAHE3_B/H provides symmetrical clamping in both forward and reverse directions, unlike unidirectional "A" variants. This makes SMBJ16CAHE3_B/H ideal for protecting AC-coupled signals, differential buses, or any circuit where voltage polarity reversal may occur during transients.
Is SMBJ16CAHE3_B/H compatible with lead-free reflow soldering?
Yes, SMBJ16CAHE3_B/H is rated MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C, fully compliant with standard lead-free soldering processes. Its matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability requirements, ensuring reliable wetting and joint formation.
How does the clamping voltage of SMBJ16CAHE3_B/H compare to its breakdown voltage?
SMBJ16CAHE3_B/H has a VBR range of 17.8–19.7 V at 1 mA and clamps to a maximum of 26.0 V at 23.1 A. This results in a clamping ratio (VC/VBR) of approximately 1.46, indicating efficient voltage limiting with minimal overvoltage margin - critical for safeguarding 3.3 V or 5 V logic interfaces.
Can SMBJ16CAHE3_B/H be used in place of a unidirectional SMBJ16A variant?
No - SMBJ16CAHE3_B/H is bidirectional and lacks polarity marking, whereas SMBJ16A is unidirectional with cathode band identification. Substituting SMBJ16CAHE3_B/H for SMBJ16A may cause improper clamping on DC-biased lines; use only where bidirectional protection is explicitly required and circuit topology supports it.
What is the significance of the "HE3" and "_B/H" suffixes in SMBJ16CAHE3_B/H?
"HE3" indicates RoHS-compliant construction with AEC-Q101 qualification; "_B/H" specifies packaging in 7" diameter tape-and-reel format with 750 units per reel. This full designation confirms SMBJ16CAHE3_B/H meets automotive reliability standards and arrives in SMT-ready packaging optimized for high-volume placement equipment.
