Product details
Overview
SMBJ16AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping inductive switching transients and ESD events. It features a 16 V stand-off voltage (VWM), 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 to protect MOSFET gates, sensor signal lines, and microcontroller I/O in industrial motor drives.
For engineers reviewing the SMBJ16AHE3_A/I datasheet, SMBJ16AHE3_A/I pinout, SMBJ16AHE3_A/I application, or SMBJ16AHE3_A/I equivalent, key selection criteria include its AEC-Q101 qualification status, low 1.0 μA reverse leakage at VWM, 0.089 %/°C temperature coefficient of breakdown voltage, and compatibility with automated SMT placement on standard PCB pad layouts per JEDEC DO-214AA footprint.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-banded polarity, leveraging a glass-passivated silicon junction for stable avalanche breakdown behavior. Its 17.8–19.7 V breakdown voltage range (VBR at 1.0 mA IT) ensures reliable turn-on before system-level damage thresholds are exceeded in 12 V and 15 V rail protection schemes.
The device delivers 600 W surge capability under standardized 10/1000 μs waveform conditions, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling robust transient energy absorption without thermal runaway when mounted on 5.0 mm × 5.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working limit for 12–15 V systems. |
| VBR min/max | 17.8 V / 19.7 V - Breakdown occurs within this range at 1.0 mA test current; ensures predictable turn-on margin above VWM. |
| VC @ IPPM | 26.0 V - Clamped voltage at 23.1 A peak pulse current; limits downstream voltage stress during worst-case transients. |
| IPPM | 23.1 A - Peak surge current supported under 10/1000 μs waveform; determines survivability against lightning or inductive kick events. |
| ID @ VWM | 1.0 μA - Reverse leakage at rated stand-off voltage; low value minimizes standby power loss and avoids false triggering. |
| PPPM | 600 W - Peak pulse power rating; defines transient energy handling capacity per IEEE C62.35-compliant surge profile. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and high-temperature industrial environments. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; meets UL 94 V-0 flammability rating and MSL Level 1 (peak reflow 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to protected circuit ground or low-side reference. | Provides return path during clamping; must be routed with low-inductance trace to minimize voltage overshoot. |
| Cathode | Current exit point in forward bias; marked by band on package body; connects to protected line (e.g., signal or power rail). | Defines polarity-sensitive clamping direction; reverse connection renders device non-functional for unidirectional suppression. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing-enables use in ADAS sensors and body control modules. |
| 600 W peak pulse power | Handles high-energy transients from relay coil de-energization or load dump without degradation, per 10/1000 μs waveform. |
| Glass passivated junction | Ensures stable VBR over time and temperature, with minimal parameter drift across 1000+ surge events. |
| Low incremental surge resistance | Minimizes VC rise under high di/dt conditions, improving clamping precision for fast-rising ESD pulses. |
| MSL Level 1 rating | Allows unlimited floor life and single-reflow processing at 260 °C peak, simplifying manufacturing flow for high-volume SMT lines. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16AHM3_A/I | Halogen-free, RoHS-compliant variant with identical electrical specs and AEC-Q101 qualification. | No functional difference; selected where halogen-free material compliance is mandated by OEM environmental policy. | Direct drop-in replacement if halogen-free content is required; same footprint, thermal, and clamping behavior. |
| SMCJ16AHE3_A/I | Same VWM/VBR/VC specs but in larger SMC (DO-214AB) package with higher 1500 W PPPM rating and lower RθJA (50 °C/W). | Better suited for high-energy industrial surge environments where PCB space allows larger footprint and enhanced thermal dissipation. | Choose when system-level surge tests exceed 600 W; requires layout change due to larger 7.11 mm × 6.22 mm outline vs. SMB's 4.57 mm × 3.94 mm. |
Compared with SMBJ16AHE3_A/I, the SMBJ16AHM3_A/I offers identical protection performance with halogen-free construction, while the SMCJ16AHE3_A/I provides 2.5× higher surge power handling at the cost of increased board area and different thermal management requirements.

FAQ
What is the maximum clamping voltage of SMBJ16AHE3_A/I under surge conditions?
The SMBJ16AHE3_A/I exhibits a maximum clamping voltage (VC) of 26.0 V when subjected to its rated peak pulse current of 23.1 A under the standard 10/1000 μs waveform. This value is measured at the device terminals and represents the upper voltage limit imposed on the protected circuit during transient events, ensuring downstream components remain within safe operating margins.
Is SMBJ16AHE3_A/I suitable for automotive applications?
Yes, SMBJ16AHE3_A/I is AEC-Q101 qualified and explicitly designated for automotive use with ordering code suffix HE3. It undergoes rigorous stress testing-including temperature cycling, high-temperature reverse bias, and ESD-to ensure reliability in engine control units, body electronics, and ADAS sensor modules operating from −40 °C to +125 °C ambient.
How does the SMBJ16AHE3_A/I differ from bidirectional variants like SMBJ16CA?
The SMBJ16AHE3_A/I is unidirectional, with polarity defined by a cathode band and intended for DC-biased lines where only one polarity of transient needs suppression. In contrast, SMBJ16CA is bidirectional, offering symmetrical clamping for AC-coupled or floating signal paths, and carries a "CA" suffix per Vishay's naming convention-not interchangeable without circuit redesign.
What is the thermal resistance of SMBJ16AHE3_A/I, and how does it affect layout?
SMBJ16AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W. To maintain safe operation under repeated surges, Vishay specifies mounting on 0.2″ × 0.2″ (5.0 mm × 5.0 mm) copper pads per terminal-reducing effective RθJA and preventing thermal runaway during high-duty-cycle transients.
Can SMBJ16AHE3_A/I be used in place of SMBJ15A or SMBJ17A?
No-SMBJ16AHE3_A/I is not a direct substitute for SMBJ15A (15 V VWM) or SMBJ17A (17 V VWM), as its 16 V stand-off voltage defines its precise operating window. Substituting alters the clamping threshold relative to system rail voltage, risking premature conduction or insufficient protection; each variant must be selected based on exact VWM matching to the protected circuit's nominal voltage.
