Product details
Overview
SMBJ16AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR) at 1 mA, 26.0 V maximum clamping voltage (VC) at 23.1 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 µs waveform), commonly deployed on DC power rails and I/O lines in industrial motor drives and automotive ECUs.
For engineers reviewing the SMBJ16AHE3_A/H datasheet, SMBJ16AHE3_A/H pinout, SMBJ16AHE3_A/H application, or SMBJ16AHE3_A/H equivalent, key selection criteria include clamping performance under 23.1 A surge, thermal resistance (RθJA = 100 °C/W), AEC-Q101 qualification status, unidirectional polarity with cathode band marking, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the low incremental surge resistance enables rapid response to fast transients (sub-nanosecond).
The device is rated for repetitive 10/1000 µs surges at 0.01% duty cycle and supports continuous power dissipation of 5.0 W at TA = 50 °C. Junction temperature range spans −55 °C to +150 °C, and it meets MSL Level 1 per J-STD-020 with 260 °C reflow peak, making it suitable for high-reliability industrial and automotive PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin. |
| VBR (min/max) | 17.8 V / 19.7 V at IT = 1 mA - Confirmed avalanche onset range; ensures predictable turn-on across production lot. |
| VC @ IPPM | 26.0 V at 23.1 A - Clamped voltage during 10/1000 µs surge; determines protected IC's maximum stress level. |
| PPPM | 600 W - Peak transient power handling capacity; validates suitability for IEC 61000-4-5 Level 4 surges. |
| RθJA | 100 °C/W - Thermal resistance junction-to-ambient on standard 0.2" × 0.2" pads; informs derating above 25 °C ambient. |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including HTOL, TC, and ESD testing per AEC specification. |

Use Value: Provides 26.0 V clamping without degrading USB 2.0/3.2 signal integrity due to minimal parasitic capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16AHM3_A/H | Halogen-free variant with identical electrical specs and AEC-Q101 qualification; same SMB package and pinout. | No functional difference; selected where halogen-free compliance is mandated by OEM or regional regulation. | Choose SMBJ16AHM3_A/H when RoHS + halogen-free material declaration is required; otherwise SMBJ16AHE3_A/H suffices. |
| SMAJ16AHE3/A | Lower 400 W PPPM rating, 30.0 V VC at 14.3 A IPPM, SMA (DO-214AC) package - smaller footprint but reduced surge capability. | Not recommended for automotive load dump or industrial 600 W surge requirements; suitable for consumer-grade ESD-only protection. | Select SMAJ16AHE3/A only for space-constrained, non-automotive designs where 400 W surge margin is sufficient. |
Compared with SMBJ16AHM3_A/H, SMBJ16AHE3_A/H offers identical protection performance with standard RoHS compliance; versus SMAJ16AHE3/A, it delivers 50% higher surge power handling and tighter clamping in the same application space-critical for automotive and industrial reliability.

FAQ
What is the clamping voltage of SMBJ16AHE3_A/H at its rated peak pulse current?
The SMBJ16AHE3_A/H has a maximum clamping voltage (VC) of 26.0 V at 23.1 A peak pulse current (IPPM), measured using the standardized 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is confirmed per Vishay Document Number 88392, page 2. The SMBJ16AHE3_A/H maintains this clamping performance across its full operating temperature range.
Is SMBJ16AHE3_A/H qualified for automotive applications?
Yes, SMBJ16AHE3_A/H is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet (Document Number 88392, page 1 and ordering table). This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD, validating its use in automotive powertrain and body electronics. The "HE3" suffix denotes RoHS-compliant and AEC-Q101 qualified construction, confirming SMBJ16AHE3_A/H meets automotive reliability standards.
What is the thermal resistance of SMBJ16AHE3_A/H, and how does it affect layout design?
The SMBJ16AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value requires PCB designers to allocate adequate copper area and consider ambient temperature derating-e.g., at 70 °C ambient, maximum continuous power drops to ~2.5 W. The SMBJ16AHE3_A/H datasheet specifies this condition in the Thermal Characteristics table (page 3), directly informing heatsinking and spacing decisions.
How does the unidirectional configuration of SMBJ16AHE3_A/H impact circuit connection?
The SMBJ16AHE3_A/H is unidirectional, meaning it conducts only in reverse bias above VBR and blocks forward current up to VF = 3.5 V at 50 A. Its cathode is marked by a band on the SMB package body and must be connected to the line being protected (e.g., 12 V rail), while the anode connects to ground. This configuration prevents forward conduction during normal operation and ensures precise clamping only during overvoltage events-unlike bidirectional variants which protect both polarities.
What packaging and reel options are available for SMBJ16AHE3_A/H?
SMBJ16AHE3_A/H is supplied in 7" diameter plastic tape and reel with a base quantity of 750 units per reel (package code H), as specified in the Vishay ordering information table (page 3 of Document 88392). The "_A/H" suffix confirms this packaging format. It is compatible with standard SMT pick-and-place equipment and meets J-STD-002 and JESD 22-B102 solderability requirements, ensuring reliable automated assembly for SMBJ16AHE3_A/H in high-volume production.
