Product details
Overview
SMBG9.0C-E3/52 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping voltage transients on signal or 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 rating with 10/1000 μs waveform - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the SMBG9.0C-E3/52 datasheet, SMBG9.0C-E3/52 pinout, SMBG9.0C-E3/52 application, or SMBG9.0C-E3/52 equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, RoHS-compliant E3 termination, MSL Level 1 moisture sensitivity, and thermal resistance (RθJA = 100 °C/W) for PCB layout thermal management.
Technical Context
This device operates as a bi-directional avalanche diode, responding symmetrically to positive and negative transients without polarity marking. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for protecting sensitive inputs against ESD and inductive switching spikes.
Rated for -55 °C to +150 °C junction temperature, it supports automotive-grade reliability per AEC-Q101 and meets UL 497B recognition. The DO-215AA package provides 0.2" × 0.2" copper pad thermal performance and complies with J-STD-002 solderability and JESD 201 Class 1A whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 10.0 V / 11.1 V at IT = 1 mA - ensures reliable avalanche initiation across manufacturing lot |
| VC @ IPPM | 15.4 V at 39.0 A - defines worst-case clamped voltage seen by protected circuit during 10/1000 μs surge |
| PPPM | 600 W - peak transient energy handling capacity under standardized 10/1000 μs waveform |
| ID @ VWM | 1.0 μA - ultra-low leakage preserves signal integrity in high-impedance interfaces |
| TJ max. | +150 °C - enables operation in under-hood automotive or industrial ambient environments |

Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load-dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bi-directional clamping element placed directly at connector entry point to shunt transients before reaching ASIC or MCU input pins. Use Value: Limits voltage excursion to ≤15.4 V during 39 A surge, preserving signal fidelity and preventing latch-up in downstream ICs. | Use Scenario: Shielding PLC digital input modules from field-wiring induced surges due to relay coil switching or lightning coupling. IC Role / Device Role / Timing Role: Primary front-end TVS on 24 V DC input lines, mounted adjacent to terminal block with minimum trace length. Use Value: Absorbs 600 W transient energy while maintaining <1.0 μA leakage at 9.0 V, ensuring stable logic-level detection. |
| Telecom Line Interface | Consumer USB/Display Port ESD Protection |
Use Scenario: Safeguarding Ethernet PHY magnetics and RJ45 jack connections against EFT and surge per IEC 61000-4-4/5. IC Role / Device Role / Timing Role: Secondary protection stage after gas discharge tube (GDT), clamping residual overshoot on differential pairs. Use Value: Symmetric 10.0–11.1 V VBR ensures balanced clamping on both conductors, minimizing common-mode distortion. | Use Scenario: Board-level ESD protection for HDMI, USB 2.0, or DisplayPort signal lanes in set-top boxes and monitors. IC Role / Device Role / Timing Role: Low-capacitance bi-directional TVS placed immediately before connector to divert ±8 kV HBM ESD events. Use Value: Sub-1 μA leakage at 9.0 V prevents signal attenuation; DO-215AA footprint allows tight routing near high-speed traces. |
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-E3/52 | Same VWM/VBR/VC specs but SMBJ package (DO-214AA); RθJA = 85 °C/W vs. 100 °C/W | Higher thermal efficiency; preferred where board space permits larger footprint | Select SMBJ9.0CA-E3/52 when higher power derating margin or lower junction temperature rise is required. |
| 1.5KE9.1C | Through-hole TO-218 package; same 9.1 V VWM but higher VC (14.5 V) and PPPM (1500 W) | Used in legacy power supply inputs; not suitable for automated SMT assembly | Choose 1.5KE9.1C only for through-hole prototyping or high-energy primary-stage protection where SMT is impractical. |
Compared with SMBJ9.0CA-E3/52 and 1.5KE9.1C, SMBG9.0C-E3/52 offers optimal balance of compact DO-215AA footprint, AEC-Q101 qualification, and verified 600 W surge capability - making it the preferred choice for space-constrained automotive and industrial SMT designs requiring bi-directional clamping.

FAQ
What is the polarity configuration of SMBG9.0C-E3/52?
SMBG9.0C-E3/52 is a bi-directional TVS diode with no polarity marking - its symmetrical avalanche structure clamps voltage transients equally in both directions. Unlike uni-directional variants (e.g., SMBG9.0A), it lacks a cathode band and may be installed without orientation concern, simplifying automated placement and reducing assembly errors.
Does SMBG9.0C-E3/52 meet automotive qualification standards?
Yes, SMBG9.0C-E3/52 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. This qualification covers stress testing for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life - all performed per the AEC-Q101 standard.
What is the maximum clamping voltage of SMBG9.0C-E3/52 under surge conditions?
The maximum clamping voltage (VC) of SMBG9.0C-E3/52 is 15.4 V at 39.0 A peak pulse current (IPPM), measured using the standardized 10/1000 μs waveform. This value represents the worst-case voltage imposed on the protected circuit during transient events and is critical for ensuring downstream ICs remain within absolute maximum ratings.
How does the DO-215AA package of SMBG9.0C-E3/52 affect thermal performance?
The DO-215AA (SMBG) package of SMBG9.0C-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads. This value informs PCB layout decisions - adequate copper area and thermal vias are required to maintain junction temperature below 150 °C during repetitive 600 W surges.
Is SMBG9.0C-E3/52 compatible with lead-free reflow processes?
Yes, SMBG9.0C-E3/52 is rated for MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C, making it fully compatible with standard lead-free soldering profiles. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102, and the E3 suffix confirms JESD 201 Class 1A whisker resistance.
