Product details
Overview
SMBG13CAHE3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for clamping ESD and surge transients on signal/power lines. It features 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), 21.5 V maximum clamping voltage (VC) at 27.9 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMBG13CAHE3/5B datasheet, SMBG13CAHE3/5B pinout, SMBG13CAHE3/5B application, or SMBG13CAHE3/5B equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VBR ≈ 1.45), 1.0 μA max reverse leakage at VWM, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR, VC, and IPPM specifications in either direction. Its glass-passivated junction ensures stable avalanche characteristics and fast response time (<1 ns), while the low incremental surge resistance supports effective energy diversion during transient events.
The device is rated for TJ = –55 °C to +150 °C operation and derates linearly above 25 °C ambient per Fig. 2. Thermal resistance is RθJA = 100 °C/W (on 0.2" × 0.2" pads) and RθJL = 20 °C/W, enabling robust thermal performance in compact automotive and industrial PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal line operating margin. |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 21.5 V at 27.9 A - Clamped voltage under 600 W 10/1000 μs surge; determines protected circuit's maximum stress level. |
| IPPM | 27.9 A - Peak pulse current handling capacity; defines surge immunity level for IEC 61000-4-5 Level 3/4 compliance. |
| PPPM | 600 W - Peak pulse power rating (10/1000 μs, 0.01% duty cycle); validates suitability for repetitive surge environments. |
| Leakage @ VWM | ≤1.0 μA - Ultra-low reverse leakage ensures minimal signal distortion and power loss in high-impedance interfaces. |
| TJ max | +150 °C - Maximum junction temperature; supports under-hood automotive deployment without derating penalties. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBG13CA-M3/5B | Halogen-free, RoHS-compliant variant; identical electrical specs and AEC-Q101 qualification. | No functional difference; selected when halogen-free material compliance is mandated by OEM spec. | Choose SMBG13CA-M3/5B for green manufacturing programs requiring halogen-free bill-of-materials. |
| SMCJ13CAHE3/5B | Higher PPPM = 1500 W, larger SMC (DO-214AB) package, same VWM/VBR/VC ratings. | Used where higher surge energy absorption is required (e.g., 48 V battery systems), but requires larger PCB area. | Choose SMCJ13CAHE3/5B only when 600 W is insufficient and board space allows SMC footprint. |
Compared with SMBG13CAHE3/5B, SMBG13CA-M3/5B offers identical protection performance with halogen-free construction, while SMCJ13CAHE3/5B trades compact SMBG size for 2.5× higher surge power handling-making SMBG13CAHE3/5B optimal for space-constrained AEC-Q101 automotive modules needing precise 600 W capability.

FAQ
What is the clamping voltage of SMBG13CAHE3/5B and how is it measured?
The SMBG13CAHE3/5B has a maximum clamping voltage (VC) of 21.5 V, measured at its peak pulse current (IPPM) of 27.9 A using a standardized 10/1000 μs double-exponential surge waveform. This value is guaranteed per the Vishay datasheet (Doc #88456, Rev 09-Jan-2024) and reflects worst-case voltage seen by downstream circuitry during surge events. The SMBG13CAHE3/5B maintains this clamping performance bidirectionally.
Is SMBG13CAHE3/5B suitable for automotive applications?
Yes, SMBG13CAHE3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood and cabin modules. Its –55 °C to +150 °C operating range, MSL Level 1 reflow compatibility, and validation against ISO 7637-2 and IEC 61000-4-5 make it appropriate for CAN bus protection, sensor interfaces, and infotainment systems. The "HE3" suffix confirms AEC-Q101 qualification per Vishay's ordering nomenclature.
What does the "CA" suffix indicate in SMBG13CAHE3/5B?
The "CA" suffix in SMBG13CAHE3/5B denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., SMBG13A), SMBG13CAHE3/5B has no polarity marking and exhibits identical VBR, VC, and IPPM characteristics in either direction-critical for protecting AC-coupled or differential signal lines like CAN or RS-485.
How does SMBG13CAHE3/5B compare to SMBG13AHE3/5B?
SMBG13CAHE3/5B is bidirectional with symmetrical clamping, while SMBG13AHE3/5B is unidirectional and includes a cathode band marking. Electrically, SMBG13CAHE3/5B has identical VWM (13 V), VBR (14.4–15.9 V), and VC (21.5 V) ratings but lacks forward voltage (VF) specification since it conducts in both directions. SMBG13AHE3/5B specifies VF = 3.5 V at 50 A, making it unsuitable for AC or differential applications where reverse conduction must be controlled.
What is the moisture sensitivity level (MSL) and reflow profile for SMBG13CAHE3/5B?
SMBG13CAHE3/5B meets MSL Level 1 per J-STD-020, allowing unlimited floor life and compatibility with standard lead-free reflow profiles. Its maximum peak reflow temperature is 260 °C, and it is qualified for soldering per J-STD-002 and JESD 22-B102. The matte tin-plated leads ensure reliable wetting on OSP- or ENIG-finished PCBs without requiring baking prior to assembly.
