Product details
Overview
SMBJ10CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping ESD and surge transients on signal/power lines. It features 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V maximum clamping voltage (VC) at 35.3 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs waveform), used in industrial sensor interface protection.
For engineers reviewing the SMBJ10CAHE3_A/I datasheet, SMBJ10CAHE3_A/I pinout, SMBJ10CAHE3_A/I application, or SMBJ10CAHE3_A/I equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (−55 to +150 °C), and bidirectional clamping behavior critical for automotive and industrial surge design.
Technical Context
This TVS operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal lines without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1.0 μA at VWM), while the low incremental surge resistance supports consistent clamping under repetitive transients.
The device complies with ANSI/IEEE C62.35 surge standards and meets J-STD-020 MSL Level 1 (260 °C reflow peak), making it suitable for high-reliability automated SMT assembly. Its 100 °C/W junction-to-ambient thermal resistance requires minimal PCB copper area (0.2" × 0.2") for rated 600 W pulse handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal swing margin. |
| VBR min/max | 11.1 V / 12.3 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 17.0 V at 35.3 A - Clamped voltage during 600 W 10/1000 μs surge; determines protected circuit's maximum stress level. |
| PPPM | 600 W - Peak pulse power rating per 10/1000 μs waveform; defines single-event surge energy absorption capability. |
| ID @ VWM | ≤1.0 μA - Reverse leakage current at stand-off voltage; ensures negligible standby power loss and signal integrity. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive or high-ambient industrial environments. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient on standard 0.2" × 0.2" pads; guides heatsinking requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA-E3/52 | No AEC-Q101 qualification; commercial-grade only; same VWM, VBR, VC, and PPPM specs. | Suitable for non-automotive industrial or consumer applications where automotive reliability certification is not required. | Select SMBJ10CAHE3_A/I when AEC-Q101 compliance is mandatory; choose SMBJ10CA-E3/52 for cost-sensitive commercial designs. |
| SMAJ10CAHE3_A/I | Lower PPPM (400 W vs. 600 W); SMA package (smaller footprint, higher RθJA = 140 °C/W); identical VWM/VBR/VC. | Better suited for space-constrained layouts with lower surge threat levels (e.g., I²C, UART), not for high-energy CAN or power rail clamping. | Use SMAJ10CAHE3_A/I only if board area is critical and surge energy remains ≤400 W; retain SMBJ10CAHE3_A/I for full 600 W capability. |

FAQ
What does the "CA" suffix indicate in SMBJ10CAHE3_A/I?
The "CA" suffix denotes a bidirectional configuration, meaning SMBJ10CAHE3_A/I provides symmetrical clamping for both positive and negative transients. Unlike unidirectional variants (e.g., SMBJ10A), it has no cathode marking and functions identically regardless of voltage polarity applied across its terminals - essential for protecting AC-coupled or differential signal lines like CAN or RS-485 where polarity reversal occurs.
Is SMBJ10CAHE3_A/I suitable for IEC 61000-4-5 surge testing?
Yes, SMBJ10CAHE3_A/I is rated for 600 W peak pulse power with a 10/1000 μs waveform, which covers IEC 61000-4-5 Level 4 (4 kV line-to-ground, 2 Ω source impedance) when mounted per Vishay's recommended 0.2" × 0.2" copper pad layout. Its 17.0 V clamping voltage at 35.3 A ensures protected circuits remain below typical 20 V absolute maximum ratings, satisfying system-level surge immunity requirements.
How does the HE3 suffix affect SMBJ10CAHE3_A/I's qualifications?
The "HE3" suffix indicates SMBJ10CAHE3_A/I is RoHS-compliant and AEC-Q101 qualified - validated for automotive applications including temperature cycling, humidity bias, and mechanical shock tests. This distinguishes it from commercial-grade variants (e.g., E3 or M3), making SMBJ10CAHE3_A/I appropriate for engine control, ADAS, and body electronics where extended temperature operation (−55 to +150 °C) and long-term reliability are mandated.
What is the thermal performance limitation of SMBJ10CAHE3_A/I in real-world PCB layouts?
SMBJ10CAHE3_A/I has a typical RθJA of 100 °C/W when mounted on minimum 0.2" × 0.2" copper pads per terminal. In compact layouts with reduced copper area, junction temperature rise increases proportionally - e.g., doubling RθJA to 200 °C/W limits usable pulse repetition rate. For sustained surge duty cycles >0.01 %, derating per Figure 2 in the datasheet is required to maintain TJ ≤150 °C, confirming SMBJ10CAHE3_A/I's thermal envelope depends critically on PCB layout.
Can SMBJ10CAHE3_A/I replace SMBJ10A in an existing unidirectional design?
No - SMBJ10CAHE3_A/I is bidirectional and lacks polarity marking, whereas SMBJ10A is unidirectional with a cathode band. Direct substitution would eliminate polarity-dependent forward conduction paths and may compromise protection on DC-biased lines. If bidirectional behavior is acceptable (e.g., AC signal lines), SMBJ10CAHE3_A/I can be used; otherwise, retain SMBJ10A or select SMBJ10CAHE3_A/I only after verifying system-level polarity independence and clamping symmetry requirements.
