Product details
Overview
SMBJ6.0AHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), and clamps to ≤10.3 V at 58.3 A peak surge current - deployed in automotive power rail protection and industrial sensor interface circuits.
For engineers reviewing the SMBJ6.0AHE3/52 datasheet, SMBJ6.0AHE3/52 pinout, SMBJ6.0AHE3/52 application, or SMBJ6.0AHE3/52 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (via HE3 suffix), 100 °C/W junction-to-ambient thermal resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, conducting only when reverse voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<800 µA at VWM), while its low incremental surge resistance enables rapid energy absorption during ESD or lightning-induced transients.
The SMBJ6.0AHE3/52 is rated for repetitive 10/1000 µs surges at 0.01% duty cycle and supports operating junction temperatures from –55 °C to +150 °C. Its cathode-band marking and matte tin-plated leads comply with J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum continuous reverse operating voltage before conduction begins; sets upper limit for normal circuit operation. |
| VBR @ IT = 10 mA | 6.67–7.37 V - verified breakdown range ensuring reliable turn-on during overvoltage events without premature triggering. |
| VC @ IPPM = 58.3 A | ≤10.3 V - clamping voltage under full 600 W surge; defines worst-case voltage seen by downstream ICs during transient. |
| PPPM | 600 W - peak pulse power handling per 10/1000 µs waveform; determines survivability against common IEC 61000-4-5 surges. |
| IFSM | 100 A - non-repetitive forward surge rating (8.3 ms half-sine); supports robustness against inrush or fault currents in power rails. |
| RθJA | 100 °C/W - thermal resistance junction-to-ambient on standard 0.2" × 0.2" copper pads; informs derating above 25 °C ambient. |
| TJ max. | +150 °C - maximum junction temperature; enables use 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. Cathode identified by band marking on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / reverse surge return path | Connected to system ground or lower-potential rail in unidirectional configuration; completes clamping loop during transient. |
| Cathode | Reverse voltage sensing / clamping output | Connected to protected line (e.g., 5 V rail or sensor input); conducts when line voltage exceeds VBR, shunting surge to ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS power supplies, supporting long-term reliability under thermal cycling and vibration. |
| 600 W peak pulse power (10/1000 µs) | Withstands IEC 61000-4-5 Level 4 (4 kV) surge events without degradation when mounted per recommended pad layout. |
| Glass passivated chip junction | Ensures stable VBR tolerance and low leakage (<800 µA) across temperature and lifetime, critical for precision sensor front-ends. |
| MSL Level 1 (J-STD-020) | Allows unlimited floor life and reflow up to 260 °C peak, eliminating bake-out requirements and enabling direct placement into high-volume SMT lines. |
| Low profile SMB package | 0.220" × 0.155" footprint with 0.096" height fits dense PCB layouts; compatible with standard 7" tape-and-reel (52) feeding equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-E3/52 | Commercial-grade version; lacks AEC-Q101 qualification and automotive traceability documentation. | Suitable for consumer or industrial non-automotive designs where automotive reliability certification is not required. | Select SMBJ6.0AHE3/52 when automotive qualification, extended temperature validation, or OEM audit readiness is mandatory. |
| SMAJ6.0AHE3/A | Smaller SMA (DO-214AC) package; 400 W peak pulse power (vs. 600 W); higher RθJA (140 °C/W). | Used where board space is constrained but surge energy is lower (e.g., low-power IoT nodes). | Choose SMBJ6.0AHE3/52 for higher surge margin and better thermal performance in demanding 12 V/24 V systems. |
Compared with SMBJ6.0A-E3/52, the SMBJ6.0AHE3/52 adds AEC-Q101 validation and automotive traceability; compared with SMAJ6.0AHE3/A, it delivers 50% higher surge power handling and 29% lower thermal resistance - making it optimal for automotive and industrial power rail protection where reliability and margin are critical.

FAQ
What is the breakdown voltage range of SMBJ6.0AHE3/52 at 10 mA test current?
The SMBJ6.0AHE3/52 has a guaranteed breakdown voltage (VBR) range of 6.67 V to 7.37 V when tested at 10 mA. This specification ensures predictable turn-on behavior during overvoltage events and is validated per ANSI/IEEE C62.35 standards. The narrow tolerance supports precise circuit protection design without excessive voltage margin overhead.
Is SMBJ6.0AHE3/52 suitable for automotive applications?
Yes, SMBJ6.0AHE3/52 is AEC-Q101 qualified and designated for automotive use via the "HE3" suffix. It undergoes stress testing for temperature cycling, humidity, mechanical shock, and surge endurance per automotive reliability standards. Its –55 °C to +150 °C operating range and traceable lot documentation make it appropriate for engine control, body electronics, and ADAS power domains.
What is the maximum clamping voltage of SMBJ6.0AHE3/52 under full-rated surge current?
At its rated peak pulse current of 58.3 A (10/1000 µs waveform), the SMBJ6.0AHE3/52 clamps to a maximum of 10.3 V. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is measured under standardized test conditions with 0.2" × 0.2" copper pads per JEDEC guidelines.
Does SMBJ6.0AHE3/52 have polarity marking, and how is it oriented on PCB?
Yes, SMBJ6.0AHE3/52 is unidirectional and marked with a cathode band on the package body. During PCB layout, the banded end must connect to the line being protected (e.g., 5 V rail), while the anode connects to system ground. Reversing polarity prevents proper clamping and may cause catastrophic failure under surge conditions.
What is the thermal resistance and how does it affect SMBJ6.0AHE3/52's power derating?
The SMBJ6.0AHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads. Above 25 °C ambient, its 5.0 W steady-state power dissipation must be linearly derated - e.g., at 75 °C ambient, maximum continuous power drops to 2.5 W. Derating curves are provided in Figure 2 of the official Vishay datasheet 88392.
