Product details
Overview
P6SMB13AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 13 V breakdown voltage (VBR = 12.4–13.7 V at IT = 1.0 mA), 11.1 V stand-off voltage (VWM), and 18.2 V maximum clamping voltage (VC) at 33.0 A peak pulse current (IPPM). It delivers 600 W peak pulse power with 10/1000 µs waveform and is AEC-Q101 qualified for automotive use.
For engineers reviewing the P6SMB13AHE3_A/I datasheet, P6SMB13AHE3_A/I pinout, P6SMB13AHE3_A/I application, or P6SMB13AHE3_A/I equivalent, this device serves as a robust, low-profile overvoltage protection solution for automotive ECUs, sensor signal lines, and power rails where fast response (<1 ns), low clamping ratio (VC/VWM ≈ 1.64), and MSL Level 1 reflow compatibility are critical.
Technical Context
This unidirectional TVS diode operates by avalanche breakdown to clamp transient surges above its VWM threshold while maintaining low leakage (<5.0 µA at VWM). Its glass-passivated junction ensures stable performance under repetitive surge conditions and high temperature (TJ up to +150 °C).
The device features a low incremental surge resistance (typical Rdyn derived from VC–VBR/IPPM ≈ 0.17 Ω), enabling effective energy diversion during ESD or load-dump events. Its SMB package supports automated placement and meets UL 94 V-0 flammability rating with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA - defines precise avalanche onset range for reliable, repeatable clamping behavior |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 5.0 µA |
| VC @ IPPM | 18.2 V at 33.0 A (10/1000 µs) - clamping voltage seen by protected circuit during worst-case surge |
| PPPM | 600 W - peak transient power handling capability under standardized surge waveform |
| TJ max. | +150 °C - enables operation in under-hood automotive environments without derating |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| Package | SMB (DO-214AA) - industry-standard 2-pin surface-mount outline with 5.59 mm × 4.06 mm footprint |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; cathode indicated by band on body; terminals designed for soldering per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to ground or low-side reference in unidirectional TVS configuration | Provides low-impedance path to ground during reverse-transient clamping when cathode is held at higher potential |
| Cathode | Current exit terminal in forward bias; connected to protected line (e.g., CAN_H, sensor VOUT, supply rail) | Acts as the "input" node for transient suppression - voltage rise above VWM triggers avalanche conduction to shunt surge current to anode |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/5T | Same VBR range (12.4–13.7 V), but SMA package (smaller footprint, lower IPPM = 30.0 A, VC = 20.0 V) | Limited to lower-energy transients; not AEC-Q101 qualified | Select when board space is constrained and automotive qualification is unnecessary |
| 1.5SMC13A | Same electrical specs but SMC (DO-214AB) package - larger footprint (7.11 mm × 6.22 mm), higher thermal mass, VC = 18.2 V, IPPM = 33.0 A | Better thermal dissipation for high-duty-cycle surge environments; no AEC-Q101 variant available | Choose for industrial power supplies needing enhanced surge endurance beyond automotive duty cycle limits |
Compared with SMAJ13A-E3/5T and 1.5SMC13A, P6SMB13AHE3_A/I uniquely combines AEC-Q101 qualification, SMB footprint compactness, and full 600 W/33 A surge capability - making it the only option qualified for automotive signal-line protection where both space and reliability are non-negotiable.

FAQ
What is the breakdown voltage tolerance of P6SMB13AHE3_A/I?
The P6SMB13AHE3_A/I has a specified breakdown voltage (VBR) range of 12.4 V to 13.7 V at test current IT = 1.0 mA, representing ±5.4% tolerance around the nominal 13 V rating. This tight distribution ensures consistent clamping behavior across production lots and supports predictable circuit protection design without margin over-engineering.
Is P6SMB13AHE3_A/I suitable for bidirectional transient protection?
No, P6SMB13AHE3_A/I is a unidirectional TVS diode - it conducts only in reverse bias above VBR and blocks forward current like a standard rectifier. For bidirectional protection, Vishay offers the P6SMB13CA variant. Using P6SMB13AHE3_A/I on AC or differential lines without external polarity control may result in unintended forward conduction and failure.
What does the "HE3_A/I" suffix indicate in P6SMB13AHE3_A/I?
The "HE3" denotes RoHS-compliant and AEC-Q101 qualified construction; "A" specifies the standard revision grade; "I" indicates packaging in 13-inch tape-and-reel format (3200 units per reel). This full suffix confirms automotive-grade reliability, lead-free compliance, and high-volume SMT readiness - distinct from commercial-grade "E3" or halogen-free "HM3" variants.
How does P6SMB13AHE3_A/I perform under elevated ambient temperatures?
P6SMB13AHE3_A/I maintains full 600 W peak pulse power capability only at TA = 25 °C. Above that, power derating follows Fig. 2 in the datasheet: at 85 °C ambient, maximum PPPM drops to ~420 W; at 125 °C, it falls to ~240 W. Its +150 °C TJ max allows operation in hot locations when PCB copper area and airflow are optimized per the 0.2″ × 0.2″ pad layout recommendation.
Can P6SMB13AHE3_A/I replace P6SMB13AHE3_B/H in a design?
Yes - both share identical electrical specifications, AEC-Q101 qualification, and SMB package. The "B" vs. "A" suffix refers only to internal manufacturing lot traceability and revision control (per Note 1 on page 3); "H" vs. "I" denotes reel size (7″ vs. 13″). No electrical, thermal, or mechanical differences exist between P6SMB13AHE3_A/I and P6SMB13AHE3_B/H - they are functionally interchangeable.
