Product details
Overview
SMBG9.0CHE3/5B from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping inductive switching transients and ESD events on signal/power lines. It features 9.0 V stand-off voltage (VWM), 10.0–11.1 V breakdown voltage (VBR) at 1 mA, 15.4 V maximum clamping voltage (VC) at 39.0 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 µs waveform). It is AEC-Q101 qualified and used in automotive sensor protection circuits.
For engineers reviewing the SMBG9.0CHE3/5B datasheet, SMBG9.0CHE3/5B pinout, SMBG9.0CHE3/5B application, or SMBG9.0CHE3/5B equivalent, key selection criteria include bi-directional clamping capability, 150 °C junction temperature rating, RoHS-compliant AEC-Q101 qualification, low leakage (<1.0 µA at VWM), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamping protector in bi-directional configurations, with symmetrical avalanche breakdown behavior in both polarities. Its glass-passivated junction ensures stable VBR tolerance (±10%) and low incremental surge resistance, enabling consistent clamping performance under repetitive 10/1000 µs transients at 0.01% duty cycle.
Thermal design relies on RθJA = 100 °C/W (on 5.0 mm × 5.0 mm pads) and RθJL = 20 °C/W, supporting operation from –55 °C to +150 °C. The DO-215AA package meets UL 94 V-0 and J-STD-020 MSL Level 1 (260 °C peak reflow), with matte tin-plated leads compliant to JESD 22-B102 solderability and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 9.0 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown |
| Breakdown Voltage (VBR) | 10.0–11.1 V at 1 mA - Guaranteed avalanche initiation range; ensures reliable turn-on during transients |
| Clamping Voltage (VC) | 15.4 V at 39.0 A (10/1000 µs) - Peak voltage seen by protected circuit; determines safe IC voltage margin |
| Peak Pulse Power (PPPM) | 600 W - Sustained transient energy handling per IEC 61000-4-5; enables robust protection against lightning surges |
| Junction Temperature Range | –55 °C to +150 °C - Supports under-hood automotive and industrial environments without derating loss |
| Leakage Current (ID) | <1.0 µA at 9.0 V - Negligible standby power loss; avoids signal line loading in high-impedance interfaces |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test requirements including HTGB, TCT, HTRB |
Pinout & Package
DO-215AA (SMBG) surface-mount package: 2-terminal, bi-directional device with no polarity marking; terminals are matte tin-plated leads suitable for reflow soldering per J-STD-002. Case meets UL 94 V-0; dimensions: 4.57 mm × 3.94 mm × 2.10 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (unmarked) | Bi-directional avalanche junction | No cathode band; symmetric conduction in both directions - simplifies PCB layout and eliminates orientation errors |
| Lead 1 / Lead 2 | Current path for transient energy dissipation | Connected to internal chip via low-inductance bond wires; requires 5.0 mm × 5.0 mm copper pads for thermal and surge current handling |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables protection against IEC 61000-4-5 Level 4 surges (4 kV line-to-line) without derating in standard layouts |
| AEC-Q101 qualification | Validates reliability for automotive ECUs, ADAS sensors, and body control modules under temperature cycling and humidity stress |
| Glass passivated junction | Ensures stable VBR over lifetime and immunity to moisture-induced parameter drift in harsh environments |
| MSL Level 1 (260 °C peak) | Supports single-pass lead-free reflow without pre-baking; reduces manufacturing complexity and cost |
| Low clamping ratio (VC/VBR ≈ 1.5) | Minimizes overvoltage stress on downstream ICs - critical for 12 V automotive logic and CAN transceivers |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0CA | Same VWM (9.0 V), higher IPPM (43.0 A), higher VC (15.5 V); DO-214AA (SMB) package, not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial use only | Select when AEC-Q101 is not required and higher surge margin is needed on same PCB footprint |
| 1.5KE9.1CA | Higher PPPM (1500 W), larger DO-201AD package, VWM = 9.1 V, VC = 15.0 V at 100 A; not AEC-Q101 qualified | Through-hole mounting; unsuitable for automated SMT production | Choose for prototyping or legacy through-hole designs where board space allows larger case and higher power rating |
Compared with SMBG9.0CHE3/5B, SMBJ9.0CA offers slightly higher surge current handling but lacks automotive qualification, while 1.5KE9.1CA provides greater power capacity in a through-hole format - making SMBG9.0CHE3/5B the optimal choice for AEC-Q101-compliant SMT automotive designs requiring precise 9.0 V clamping.

FAQ
What is the polarity configuration of SMBG9.0CHE3/5B?
SMBG9.0CHE3/5B is a bi-directional transient voltage suppressor with no polarity marking on the DO-215AA package. Its symmetrical avalanche structure allows identical clamping behavior in both forward and reverse directions, eliminating orientation concerns during PCB assembly and simplifying layout for differential or AC-coupled signal lines.
Is SMBG9.0CHE3/5B suitable for automotive applications?
Yes, SMBG9.0CHE3/5B is AEC-Q101 qualified and explicitly rated for automotive use. Its construction - including glass-passivated junction, MSL Level 1 reflow compatibility, and –55 °C to +150 °C operating range - meets stress test requirements for engine control units, ADAS sensors, and body electronics where reliability under thermal cycling and humidity is critical.
What is the maximum clamping voltage of SMBG9.0CHE3/5B under surge conditions?
The maximum clamping voltage (VC) of SMBG9.0CHE3/5B is 15.4 V when subjected to a 10/1000 µs waveform at its rated peak pulse current of 39.0 A. This value is guaranteed across temperature and lifetime, ensuring downstream components like 5 V microcontrollers or CAN transceivers remain within safe operating voltage limits during transient events.
Does SMBG9.0CHE3/5B require a heatsink for standard operation?
No, SMBG9.0CHE3/5B does not require an external heatsink under typical surge conditions. Its thermal resistance (RθJA = 100 °C/W) is specified for mounting on 5.0 mm × 5.0 mm copper pads per terminal - sufficient to dissipate 600 W peak pulses with short duration and low duty cycle (0.01%). Continuous power dissipation remains negligible due to its TVS operating mode.
How does the HE3 suffix in SMBG9.0CHE3/5B affect its specifications?
The HE3 suffix in SMBG9.0CHE3/5B denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It does not alter electrical parameters versus the E3 version, but adds automotive-grade reliability validation and enhanced plating durability - making SMBG9.0CHE3/5B appropriate for mission-critical automotive production, unlike the commercial-grade E3 variant.
