Product details
Overview
SMBG13CHE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for robust overvoltage protection of DC power rails and signal lines. It features 13 V standoff voltage (VWM), 14.4–15.9 V breakdown voltage (VBR at 1 mA), 21.5 V clamping voltage (VC) at 27.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive engine control units to safeguard microcontroller I/O against load dump transients.
For engineers reviewing the SMBG13CHE3/5B datasheet, SMBG13CHE3/5B pinout, SMBG13CHE3/5B application, or SMBG13CHE3/5B equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance data, RoHS-compliant material categorization, and precise mechanical dimensions per DO-215AA outline - all critical for ESD/surge co-design, PCB layout validation, and automotive-grade BOM sourcing.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<1 µA leakage at 13 V), then rapidly avalanches below 16 V to clamp transient energy into ground. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low dynamic impedance (≈0.7 Ω derived from ΔVC/ΔIPPM), enabling consistent clamping across temperature (−55 °C to +150 °C).
Designed for automated SMT placement, the device meets J-STD-020 MSL Level 1 (peak reflow 260 °C), uses matte tin-plated leads compliant with JESD 22-B102, and carries HE3 suffix confirming AEC-Q101 qualification - making it suitable for under-hood automotive modules where reliability under thermal cycling and mechanical shock is mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin for 12 V automotive systems. |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - tight 5% tolerance ensures predictable turn-on threshold across production lots and temperature. |
| VC @ IPPM | 21.5 V at 27.9 A - clamping voltage during 600 W transient; limits stress on downstream ICs to <22 V during ISO 7637-2 Pulse 5a events. |
| PPPM | 600 W - peak pulse power handling with 10/1000 µs waveform; supports repetitive surge duty cycle up to 0.01%. |
| RθJA | 100 °C/W - junction-to-ambient thermal resistance on 5 mm × 5 mm copper pads; enables thermal derating above 25 °C ambient. |
| IFSM | 100 A - non-repetitive forward surge rating (8.3 ms half-sine); validates robustness against battery reverse-connection faults. |
| Junction Temp | −55 °C to +150 °C - full operational range compatible with engine compartment environments. |
Pinout & Package
DO-215AA (SMBG) surface-mount package: gull-wing leads, 0.235–0.255 inch body length, 0.130–0.155 inch width, 0.075–0.095 inch height; cathode band marked on one end; mounted on 5.0 mm × 5.0 mm copper pads per terminal per datasheet Fig. 2.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13AHE3/5B | Same VWM (13 V), identical DO-214AA (SMB) package but 5% larger footprint; RθJA = 85 °C/W vs. 100 °C/W. | Higher power density (600 W same rating) but requires larger pad layout; not DO-215AA footprint-compatible. | Select SMBJ13AHE3/5B only if board space allows larger SMB package and lower thermal resistance is prioritized. |
| 1.5KE13AHE3/54 | Through-hole TO-204AA (DO-41); 13 V VWM, 21.5 V VC, but 1500 W rating and slower response due to higher junction capacitance. | Not SMT-compatible; used in legacy industrial power supplies where manual assembly and higher surge margin are acceptable. | Choose 1.5KE13AHE3/54 only for through-hole designs requiring >600 W headroom and where rework flexibility outweighs automated assembly needs. |
Compared with SMBG13CHE3/5B, SMBJ13AHE3/5B offers better thermal performance but demands PCB layout revision, while 1.5KE13AHE3/54 provides higher surge rating at the cost of SMT incompatibility and slower clamping - making SMBG13CHE3/5B the optimal choice for new AEC-Q101-compliant SMT automotive designs with strict footprint constraints.

FAQ
What is the clamping voltage of SMBG13CHE3/5B at its rated peak pulse current?
The SMBG13CHE3/5B has a maximum clamping voltage (VC) of 21.5 V at 27.9 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream circuitry sees no more than 21.5 V during a 600 W transient event. The SMBG13CHE3/5B maintains this clamping performance across its full operating temperature range of −55 °C to +150 °C.
Is SMBG13CHE3/5B suitable for automotive applications?
Yes, SMBG13CHE3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood engine control units and body electronics. Its HE3 suffix confirms compliance with AEC-Q101 stress tests, and its DO-215AA package meets MSL Level 1 for lead-free reflow. The SMBG13CHE3/5B is designed to withstand ISO 7637-2 load dump and pulse 1 transients common in 12 V vehicle electrical systems.
What does the "HE3" suffix mean in SMBG13CHE3/5B?
The "HE3" suffix in SMBG13CHE3/5B indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. Unlike standard "E3" parts, HE3 devices undergo additional automotive-grade reliability testing and use matte tin plating validated for long-term stability in thermal cycling environments. The SMBG13CHE3/5B's HE3 marking is documented in Vishay's ordering information table and thermal characteristics section.
How does SMBG13CHE3/5B differ from SMBG13A-E3/5B?
SMBG13CHE3/5B is AEC-Q101 qualified and JESD 201 Class 2 whisker-tested, whereas SMBG13A-E3/5B is commercial-grade only (E3 suffix). Both share identical electrical specs (VWM = 13 V, VC = 21.5 V) and DO-215AA packaging, but SMBG13CHE3/5B is certified for automotive production use with full traceability and extended reliability validation. For automotive BOMs, SMBG13CHE3/5B is the required variant.
What is the thermal resistance of SMBG13CHE3/5B, and how does it affect layout?
The SMBG13CHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. This value requires PCB designers to allocate sufficient copper area for heat dissipation during repetitive surge events. Reducing pad size increases RθJA, accelerating thermal derating - for example, at 100 °C ambient, the SMBG13CHE3/5B's surge capability drops by ~50% versus 25 °C operation.
